Go to species: b c aberconwayi Irrorata Shrubs, 5 to 8 ft. Flowers (May) are white to pale rose with crimson spots. Unusual, stiff upward-curving leaves. Limited distribution in the wild. Found on mountain summits from 6,000 to 8,000 ft. China 64/015 ('His Lordship') WGP-ACL (+5). An award form with flowers white spotted red. AM 1945 73/001 EXB: FR: PHB (+5). 78/015 'Westhaven' MCG (+5). Flowers white with maroon spots. adenogynum Taliensia Broadly upright but compact-growing evergreen shrubs. The leaves have a distinctive spongy to somewhat woolly yellowish to greenish brown indumentum on the undersides. The flowers (mid-spring) are white to rose or rose-purple, often with purple or brownish spots. A free- flowering and relatively easily grown member of this subsection with outstanding foliage. Native to China (SE Tibet, W Yunnan & SW Sichuan) where it occurs on open slopes above tree-line from 10,000 to 14,000 ft. 75/248 (adenophorum) FD-WEB (-5).

A form with white to green- white flowers. aganniphum var. aganniphum Taliensia Compact to quite large evergreen shrubs, generally smaller in cultivation. A variable, widespread and common species in the wild. The attractive foliage is covered with a pale indumentum beneath. The flowers (mid-spring) are borne in a dense rounded inflorescence and vary in color from white to rose or deep pink, typically with numerous reddish spots. Very slow-growing and rather difficult and thus rare in cultivation. A choice collector's species. Native to China (SE Tibet, NW Yunnan & W Sichuan) where it is found in a wide variety of habitats from 11,000 to 15,000 ft. 77/771 (glaucopeplum) F 25520: WGP (-5) 92/014 KW#5863:LEO ((10\R3\3). I have not seen this clone in bloom. 273sd1997 JN#639:RSBG (- 10\R3\3). Grown from seed collected by Jens Nielsen at 12,500 ft. in the Tisongmu Shan, near Zhongdian in Yunnan, China from "beautiful foliage plants with striking orange-pink indumentum turning rusty fawn. 275sd1997 JN#379:RSBG ('10\R3\3). Grown from seed collected wild by Jens Nielsen at 13,300 ft. in the Beima Shan, Yunnan, China. 350sd1997 JN#189:RSBG ('10\R3\3). Grown from seed collected wild by Jens Nielsen at 13,780 ft. in the Daxue Shan, Yunnan, China. 385sd1997 BH#095:RSBG ('10\R3\3). Grown from seed collected wild at 13,125 ft. near the Beima Shan, Yunnan, China. 443sd97 (Glaucopeplum Group) JN#656:RSBG (- 10\R3\3). Grown from seed collected wild at 13,100 ft. in the Haba Shan, Zhongdian, NW Yunnan, China. Shiny, dark green leaves with a pale indumentum on these stout seedlings. These should have a darker and thinner indumentum than the typical aganniphum. aganniphum var. flavorufum Taliensia Generally small shrubs with some forms reaching 10 ft. Flowers (April-May) are white or white flushed with pink. Distinctive indumentum splits into small irregular patches and is buff to red-brown when mature. Abundant in the wild and merges completely with var. aganniphum and found on the margins of forest, among boulders and scrub on slopes, and on cliffs from 11,000 to 15,000 ft. China 70/407 (flavorufum) F 14368: RBG (-5) White flowers in April aganniphum var. flavorufum affinity Taliensia This is an interesting and beautiful plant which has been grown and distributed for years as "bathyphyllum" from the Windsor collection under Forrest#14718. Recent chemical and morphological studies have shown that this clone is closer to aganniphum var. flavorufum and that the Windsor plant is misnamed and probably not derived from F#14718 (we now know that the real bathyphyllum is a naturally occurring hybrid between proteoides and aganniphum which looks completely different). Nomenclatural shenanigans aside, this is a fantastic foliage plant with a distinctive splitting brownish indumentum on the undersides of shiny ovate-elliptic leaves. Forms a beautiful rounded evergreen shrub in partial shade. I have not seen the flowers but they are probably the typical Taliensia white or white flushed rose in mid-spring. 1976/265 Windsor:Berg (- 10\R2\3). A really nice looking plant for well-drained soils in a bright but not too hot exposure. x agastum Irrorata Attractive early-blooming evergreen shrubs. The flowers are pale to deep pink or sometimes white flushed pink but always blotched and usually spotted. Recent field work has proven that this "species" is actually a natural hybrid, probably resulting from crosses between irroratum and arboreum ssp. delavayi and possibly arboreum ssp. delavayi x decorum. Rare in cultivation and found only in W Yunnan & Guizhou(?), China where it occurs in thickets and forests from 5,000(?) to 11,000 ft. 237sd95 PW#93:RSBG (0 to +10?\R1\8). Grown from seed collected wild at 5,450 ft. in Guizhou Province, China. 247sd95 PW#98:RSBG (0 to +10?\R1\8). Grown from seed collected wild at 5,750 ft. in Guizhou Province, China. albertsenianum Neriiflora Shrubs, 3 to 6 ft. Flowers (April) are bright crimson rose. Leaves with bistrate indumentum, an unusual feature for a species in this subsection, brown in color, the upper layer loose and woolly, and the lower felted and compact. Collected only once in the wild and still rare in cultivation. Found in open forests at 10,000 ft. China 75/093 F 14195: WGP (+5). Collected by George Forrest on the divide between the Mekong and Salween Rivers during his 1912-14 expedition to upper Yunnan Province. A form with red flowers. albiflorum Candidastrum Upright-growing deciduous shrubs with glossy elliptic to oblong leaves. The widely bell-shaped white flowers (early to mid-summer) are borne in axillary clusters of two (or singly) along the erect stems. A difficult and rare species in cultivation, requiring excellent drainage and a cool but bright position. An extremely unusual and quite unique species unrelated to any other. Widespread and common in many forested mountainous areas of western North America from 4,000 to 7,200 ft. 176sd96 95RP#020:RSBG (- 20\R3\3). Grown from seed collected wild by Rick Peterson in the Olympic Mountains of Washington. 232sd97 RSBG (- 20\R3\3). Grown from seed collected wild by Richie Steffen in the Cascade Mountains of Washington. 220sd1998 RSBG (- 20\R3\3). Grown from seed collected wild at 4,500 ft. in the Cascade Mountains of Washington State. albrechtii Sciadorhodion Upright-growing, deciduous shrubs with obovate hairy leaves. The exquisite flowers (early to mid-spring) are rose to rose-purple, generally appearing before the newly emerging foliage. A choice and hardy azalea, perfect in the woodland garden but unfortunately, rarely seen in cultivation. Brilliant fall foliage color. Native to Japan (C Honshu to C Hokkaido) where it occurs at 3,300 ft. in subalpine habitats. 334sd1995 95ARS#362:RSBG (- 15\R1\4).

Distribution in Japan Kyushu (Kumamoto Pref., Amakusa Islands). Habitat Edges of evergreen forests on mountain slopes; ca. 300 m. Note This species distributes in restricted narrow area. However, Rhododendron weyrichii has inverted in this region recently as a result of cutting of the forests. Many hybrids between both R. amakusaense and R. weyrichii are found, even in the type locality, so the typical form of R. amakusaense is rapidly losing at present. Annotator T. Yamazaki ambiguum Triflora Upright growing but compact evergreen shrubs with shiny dark green leaves, glaucous beneath. The flowers (mid-spring) are greenish yellow to pale yellow and widely funnel-shaped. Closely related to R. triflorum but with a more compact habit and lacking an indumentum on the outer surface of the corolla. An attractive and hardy yellow-flowered lepidote, quite easy in cultivation.

Grown from seed collected wild near Sanderson in Danawha Co., West Virginia. arboreum ssp. albotomentosum Arborea This recently reclassified taxon (I had listed it as arboreum ssp. delavayi var. albotomentosum last year) was introduced by Kingdon Ward in 1956 from an isolated and distinctly different population of arboreum which he found growing on Mt. Victoria in SW Burma. This was probably his last introduction of Rhododendron seed and has proven to be quite a spectacular version of this variable species. According to Dr. David Chamberlain, this population lies between ssp. arboreum & ssp. delavayi taxonomically. The smaller than normal leaves are glossy green above with a thick whitish spongy indumentum on the underside. The scarlet to red unspotted flowers are in a compact inflorescence. So far known only from the original collection site where it occurred from 8,000 to 10,000 ft. 79/010 'Dr. Bowman' KW#21976:SCHI (+12?\R1\6). A superb selection with cardinal red flowers and deep purple nectar pouches. Blooms mid-winter in C California. arboreum ssp. arboreum Arborea Large trees, often growing to 100 ft. in the wild, hence its name, meaning tree like. Rarely under 6 ft. on exposed sites. Flowers (May) are bright red to carmine, rarely pink or white. Leaves dark green, narrowly to broadly elliptic or ovate with white to silver-colored indumentum below. Perhaps the most widespread, common and variable species in the world found from 6,000 to 9,000 ft. Native to the foothills of the Himalayas in India ( Kashmir, Punjab, Himachal Pradesh, Uttar Pradesh, Sikkim, West Bengal),N India, Nepal, Bhutan. 64/118 Leonardslee (0).

Grown from seed collected wild at 9,000 ft. in the Sikkim Himalayas from assorted plants in a large population. 513sd97 SEH#527:RSBG (+5?\R1\6). Grown from seed collected wild at 9,000 ft. in the Sikkim Himalayas from a plant with attractive carmine-pink flowers. 552sd97 SEH#566:RSBG (+5?\R1\6). Grown from seed collected wild at 9,000 ft. in the Sikkim Himalayas from a group of plants with the best red flowers I had seen on that expedition. arboreum ssp. cinnamomeum var. cinnamomeum Arborea Large evergreen shrubs with stiff lanceolate foliage. The leaves have an attractive rusty brown bistrate indumentum on the lower surface. The flowers (mid- to late spring) are white, pink, carmine or red. Found at higher elevations than ssp. arboreum and thus generally hardier. A beautiful plant in both foliage and flower. Native to open forests and rocky slopes from 9,000 to 11,500 ft. in E Nepal and NE India (West Bengal & Sikkim). 64/118 Leonardslee (0\R1\6). Rose in bud, opening to rose flowers with darker pink flecks and basal blotching. Our best 'hardy' pink arboreum. NOTE: This clone has been offered in the past as ssp. arboreum or just arboreum. Its flower color and hardiness leads me to place it within the current taxon. However, the shiny silver indumentum is that of ssp. arboreum. This clone could be an intermediate or even 'hybrid' between the two subspecies. 70/046 WOOD ((5?\R1\6). Flowers white flushed rose with a few maroon flecks. 80/103 (arboreum ssp. campbelliae) KLT (+15) 84/074 (arboreum) LOG (0). A form with delicate clear pink flowers. 94/083 BB#8801:Berg (0\R1\6).

My own collection from 9,000 ft. in the Sikkim Himalaya from a plant with deep red flowers. arboreum ssp. cinnamomeum var. roseum Arborea Large rounded to upright evergreen shrubs or trees (40 ft. or more) with stiff lanceolate foliage. Differs from ssp. cinnamomeum var. cinnamomeum in the paler, more compacted unistrate indumentum on the undersides of the leaves. The flowers (mid- to late spring) are white, pink, carmine or red. Found at higher elevations than ssp. arboreum and thus generally hardier. Completely intergrades with both ssp. arboreum and ssp. delavayi. An impressive plant in both foliage and flower. Native to open forests and rocky slopes from 8,000 to 13,000 ft. in E Nepal, NE India, Bhutan, and S Tibet. 64/118 Leonardslee (0\R1\6). Rose in bud, opening to rose (55B) flowers with darker pink flecks and basal blotching. Our best "hardy" pink arboreum. NOTE: This clone has been offered in the past as ssp. arboreum or just arboreum. Its flower color and hardiness leads me to place it within the current taxon. However, the shiny silver indumentum is that of ssp. arboreum. This clone could be an intermediate or even hybrid between the two subspecies. 71/406 (arboreum var. album) LOC: UBCP (0). White flowered form. 76/372 (arboreum var. album) TRW: WEB (0). White flowered form. 76/159 BOD (0). Trusses of rose-pink flowers. 94/083 BB#8801:Berg (0\R1\6).

My own collection from 9,000 ft. in the Sikkim Himalaya from a plant with carmine-pink flowers. 511sd97 SEH#525:RSBG (0\R1\6). My own collection from assorted plants in a large population at 9,000 ft. in the Sikkim Himalaya. NOTE: I mistakenly sold these seedlings as ssp. arboreum in last year's catalog. 552sd97 SEH#566:RSBG (0\R1\6). My own collection from 9,000 ft. in the Sikkim Himalaya from a group of plants with the best red flowers observed on the expedition. NOTE: I mistakenly sold these seedlings as ssp. arboreum in last year's catalog. 549sd1997 SEH#563:RSBG (0\R1\6). Grown from my collection of seed at 9,000 ft. in the Sikkim Himalaya from a plant with deep red flowers. arboreum ssp. delavayi var. delavayi Arborea This subspecies represents the Chinese or eastern version of R. arboreum. It grows as a large shrub and does not attain the tree-like proportions of the Himalayan arboreum. The flowers are typically deep crimson to carmine and very attractive in mid- to late spring. The leaves are glossy with deeply impressed veins above and a spongy white to fawn indumentum beneath. A widespread variety occurring in various habitats from 5,000 to 11,000 ft. in a range extending from NE India, Burma and SW China to Thailand and Vietnam. 73/345 (delavayi) (+15)Crarae (+15) 77/80246sd95 PW#91:RSBG (+10?\R1\6). Grown from seed collected wild at 5,430 ft. in Guizhou Province, China arboreum ssp. nilagiricum Arborea This subspecies is quite interesting in that it occurs only in the mountains of S India, far from any other rhododendrons excluding R. arboreum ssp. zeylanicum which occurs on the island of Sri Lanka. Subspecies nilagiricum is very similar to ssp. zeylanicum in it's bullate and convex leaves with a spongy yellow-brown indumentum on the undersides although the leaves of the former are less rounded. It also shares similar stunning deep crimson to pink flowers but blooms later (late spring to early summer) than ssp. zeylanicum. Kenneth Cox, who has observed this subspecies in the wild on numerous occasions, places it as intermediate between ssp. zeylanicum and ssp. delavayi. Occurs from 6,000 to 7,250 ft. in fairly hot and exposed situations. Should be an ideal species for areas normally considered too hot and dry for rhododendron cultivation. 171sd96 RSBG (+10?\R1\6). Quite rare in cultivation, these are grown from seed collected wild by Ken Cox in the Nilagiri Hills of southern India. Our first offering of this interesting and beautiful species. arboreum ssp. zeylanicum Arborea Slow-growing small trees to 30 ft. Late season flowers (June- July) are red to crimson-rose or carmine. With bullate leaves and fawn to tawny indumentum, spongy to the touch. A geographically isolated subspecies in the southern most extension of R. arboreum. Found in mountainous regions from 3,000 to 8,000 ft. Sri Lanka 76/225 (zeylanicum) BRO: WEB (+15). Red Flowers argipeplum Barbata Large upright shrubs with bristly branchlets and smooth, peeling reddish bark. A compact and rounded inflorescence of scarlet to crimson flowers in early spring. This species is very similar to the widely grown barbatum, really differing only in the presence of a thin indumentum on the lower leaf surface. Attractive and interesting bristly petioles and reddish new growth. A choice long-lived species for the woodland garden with ornamental foliage, flowers and bark. Native to forests from 8,000 to 13,000 ft. in NE India (Sikkim & Arunachal Pradesh), Bhutan and SE Tibet. 567sd1997 SEH#581:RSBG (0 to +5\R1\6). Grown from my collection of seed at 10,800 ft. in the Sikkim Himalaya. Beautiful foliage. Subsection Argyrophylla These are seedlings grown from seed collected at around 9,000 ft. in the Jin Pin Mountains of S Sichuan Province, China. This was a very rich area with numerous species of Rhododendron. These will probably turn out to be R. argyrophyllum itself but there was such variation in this species in the entire region that we were hesitant to put a solid name on these collections in the field without seeing the flowers. These should be hardy and long-lived plants with attractive pink to white flowers. 426sd96 SEH#078:RSBG (0'\R1'\5'). An interesting taxon with the appearance of the newly introduced R. longipes but with the white indumentum on the lower surface of the leaves one would expect from R. argyrophyllum. 445sd96 SEH#107:RSBG (0'\R1'\5'). Probably R. argyrophyllum ssp. argyrophyllum but could be something new as the area is almost unexplored and several other new species were collected there. Vigorous, attractive plants. argyrophyllum ssp. argyrophyllum Argyrophylla The typical species forms a large shrub or a small tree with leaves smooth above and a thin compacted white to silvery or fawn indumentum beneath. The flowers (mid- to late spring) are white to deep rose, often with some spots. Long-lived, hardy and easy in cultivation, this species is lovely as a specimen plant or in the woodland garden.

This clone from the original wild collection of this species. Very rare in cultivation. asterochnoum Fortunea A newly introduced species, closely related to R. calophytum. This species differs in the whitish to fawn stellate indumentum on the lower surface of the leaves (primarily on the main veins and midrib). It forms a small tree with large leaves and white flushed rose flowers with a dark red basal blotch. During an expedition to China in 1995, I observed this species growing on and among huge boulders in a deep ravine at 9,000 ft. in S Sichuan. This ravine was located in a limestone mountain range near the Yangtze river and was an exceedingly rich area for plants. Attractive large leaves. Native to C & S Sichuan, China where it grows in forests from 10,000 to 12,000 ft. 432sd96 SEH#093:RSBG (0\R1\6). One of the most exciting new introductions in years.

FCC 1932 augustinii ssp. hardyi Triflora This subspecies differs from ssp. augustinii primarily in its deciduous foliage and white to greenish white flowers with yellow-green spots in mid-spring. Fairly rare in cultivation and seldom available. Found in E Tibet and NW Yunnan, China where it occurs from 11,000 to 12,000 ft. 78/065 (hardyi) Cox-WEB (0). White flowers with a yellow center.For the serious collector. aureum var. aureum Pontica Prostrate to mounding dwarf shrubs with a creeping habit. This species is quite distinctive and unusual in that it is a dwarf alpine elepidote. Thus it has the same type of leaves and flowers as the "typical rhododendron" most people are familiar with instead of the smaller scaly leaves and flowers seen on most dwarf alpine species. The leaves are quite variable in shape and smooth on both surfaces. The flowers (early spring) are in the shape of a wide-open bell and vary in color from cream to pale yellow, often with darker spots. A rarely cultivated species ideal for the rock garden and performing well even in light shade. Extremely hardy and relatively slow growing, this species is native over a wide area of N Asia including Siberia, N China & N Japan. It is quite common in the wild and covers large areas of open slopes in some portions of its range.

Red tubular flowers with yellow lobes. chrysodoron Boothia Upright-growing evergreen shrubs with beautiful smooth and peeling, deep red-brown bark. The rather stiff and thick foliage is quite attractive, glossy green on the upper surface with golden scales on the lower. The flowers (late winter indoors, early spring outdoors) are bright to deep yellow and bell-shaped with flaring lobes. This species tends to open its flowers rather sporadically over a long period (with us) and grows too early in the season for cultivation out of doors in our climate. It is however, a distinct and in my opinion, a rather stunning species. Native to areas heavily influenced by the monsoon from 6,500 to 8,500 in W Yunnan, China and N Burma where it grows as an epiphyte or in other exceptionally well-drained areas such as on rocks and cliffs. 76/218 Glenarn (+15\R3\3). Bright canary yellow flowers with large brown anthers on this clone. Rarely offered. ciliatum Maddenia Low-growing compact evergreen shrubs with reddish brown peeling bark. The large funnel-shaped flowers are white or white flushed pink in early to mid-spring. The distinct and attractive glossy foliage is elliptic in shape with long hairs on the upper surface and fringing the margin. Tolerant of alkaline soil a fairly drought tolerant once established. Often a common species in mountain forests, boggy areas and rocky hillsides from 8,000 to 13,000 ft. in the eastern Himalayas. 80/077 LS&H 16019-Castle Howard (+10). 82/172 HED#378:HED (+10). White flowers with a slight rose blush in this form collected by Milke Danda in Nepal at 11,500 ft. 531sd1997 SEH#545:RSBG (+5\R1\4). My own collection from 11,000 ft. in the Sikkim Himalaya. 95/072 ciliatum BLM#324:Glendoick (+5\R1\4). Easy and floriferous species with attractive hairy foliage and large funnel-shaped white flushed pink flowers. Good in sun or light shade. Forms a nice low mound. ciliicalyx Maddenia Shrubs to 10 ft. Flowers (March-April) are white or pink and openly funnel-campanulate. Leaves elliptic or narrowly elliptic with dense brown scales beneath. Slightly hardier than other species of this alliance and flowers can be scented. Limited distribution in the wild: rocky slopes from 7,500 to 9,000 ft. China (Yunnan) 82/013 'Charisma' KW 20280-Pukeiti (+32) 2000/022 'Walter Maynard' Borde Hill:Dodson (+15'\R2\5). This AM form (1975) has large white flowers flushed yellow-green in the throat, flushed soft red-purple at the base of the lobes. NOTE: I incorrectly sold this as 'Walt Maynard' in the 2001 cinnabarinum ssp. cinnabarinum Cinnabarina Large upright-growing evergreen shrubs with superb pendulous flowers in late spring. These are tubular in shape and quite variable in color, ranging from red, plum-crimson, salmon-pink, pink, yellow-orange and apricot to various bicolor and even tricolor combinations. The leaves are deep green to blue-green, often glaucous, and usually narrower and without scales on the upper surface in this subspecies. Susceptible to powdery mildew which may defoliate the plant in extreme cases. Native to a wide variety of habitats from 7,000 to 13,000 ft. in the eastern Himalayas. 64/139 (var. blandfordiiflorum) Corsock (+5). Graceful tubular flowers of a red-apricot-yellow blend. 70/019 (var. roylei 'Vin Rose') Windsor (+5). Slender upright plant with pendulous open tubular flowers of plum- crimson. An Award of Merit form, 1953. 74/066 'Nepal' LS&H 21283: HYD (+5). Clusters of four to eight pendulous flowers of light orange, deepening to red at the base. AM 1977. 77/160 (Roylei Group) Berg (+5\R2\5). Glaucous red-orange flowers. 496sd97 SEH#509:RSBG (+5\R2\5). My own collection from 10,800 ft. in Sandakphu, West Bengal, India. I did not see these in bloom but they are reported to be the red to plum-crimson with a glaucous bloom form known as Roylei Group. Bright blue-green leaves on this collection. 496sd97 SEH#509:RSBG (0?\R2\5). Grown from seed collected wild at 10,800 ft. in Sandakphu, West Bengal, India. I did not see these plants in bloom but they are reported to be the red to plum-crimson with a bloom form which is known as Roylei Group. Intensely blue-green leaves. 568sd97 SEH#582:RSBG (+5\R2\5). My own collection from 10,800 ft. in the Sikkim Himalaya. The few specimens of cinnabarinum I was able to observe in bloom in this area were the orange and yellow bicolored form known as Blandfordiiflorum Group. cinnabarinum ssp. xanthocodon Cinnabarinum Similar to ssp. cinnabarinum but with shorter, more bell-shaped flowers and broader leaves with scales on the upper surface. The flowers range in color from apricot, orange, vermilion and yellow, to red-purple or plum-purple and appear in mid- to late spring. Plants formerly known as concatenans are usually lower-growing and more compact. Plants formerly known as var. purpurellum generally have smaller and more rounded, deeper green leaves and shorter bell-shaped flowers. This subspecies is much less susceptible to powdery mildew than ssp. cinnabarinum. Found in various habitats from 10,000 to 14,000 ft. in the eastern Himalayas, east of the range of ssp. cinnabarinum. 70/323 (syn. concatenans) FOR (+5). Form with large apricot- orange bells, foliage especially silvery blue in this clone. 73/305 (syn. xanthocodon) EXB - WW - PHB (0). A reliable medium sized shrub producing the best display of yellow flowers in the genus. AM 1935 74/066 'Nepal' LS&H#21283:Hydon (0 to +5\R2\5). Yellow flowers flushed red at the base on this 1977 Award of Merit form. 75/046 (syn. concatenans) KW 5874-Nymans (0) An Fcc form of a Kingdon Ward collection with apricot flowers flushed rose on the outside. 75/251 (syn. concatenans) WEB (0). A form typical in rounded glaucous leaves but the finest flowers of any in Mr. Davidian's opinion. 75/099 'Vin Rose' Windsor (0 to +5\R2\5). Deep red flowers with a waxy bloom (Roylei Group) on this 1953 Award of Merit form. 77/670 (syn. cinnararinum var. purpurellum) CRA (+5). Purple flowers. 80/078 (syn. concatenans) L&S 6560: CH (0). From the 1938 expedition by Ludlow, Sheriff & Taylor to southeastern Tibet. 82/001 (syn. cinnabarinum var. purpurellum) CI: LB (0). An Award of Merit form, 1951. 82/161 (Concatenans Group) BIR (0\R1\4). Glaucous blue-green foliage and vermilion flowers. 545sd1997 SEH#559:RSBG (0 to +5\R2\5). My own collection from 11,800 ft. in the Sikkim Himalaya. 568sd1997 SEH#582:RSBG (0 to +5\R2\5). Grown from my collection of seed at 10,800 ft. in the Sikkim Himalaya. The few specimens of cinnabarinum I was able to observe in bloom in this area were the orange and yellow bicolored form known as Blandfordiiflorum Group. Attractive blue-green foliage. cinnabarinum ssp. xanthocodon Cinnabarina Similar to ssp. cinnabarinum but with shorter, more bell-shaped flowers and broader leaves with scales on the upper surface. The flowers range in color from apricot, orange, vermilion and yellow, to red-purple or plum-purple and appear in mid- to late spring. Plants formerly known as concatenans are usually lower-growing and more compact. Plants formerly known as var. purpurellum generally have smaller and more rounded, deeper green leaves and shorter bell-shaped flowers. This subspecies is much less susceptible to powdery mildew than ssp. cinnabarinum. An outstanding foliage plant with fragrant leaves. Found in various habitats from 10,000 to 14,000 ft. in the eastern Himalayas, east of the range of ssp. cinnabarinum. 70/323 (Concatenans Group) Fortescue (0\R1\4). Intensely silver-blue foliage with apricot flowers. 73/305 Wood:Brydon (0\R1\5). Solid chrome yellow flowers. 75/046 (Concatenans Group) KW#5874:Nymans (0\R1\4). Apricot flowers flushed rose externally on this 1935 FCC form. 433sd1998 CCHH#8162:RSBG (0\R1\5). A very exciting and interesting new collection from the extreme northwestern corner of Yunnan, China. This collection is remarkable in that cinnabarinum (excluding the deciduous subspecies tamaense - which we also found in this area) is a species of the Himalayas - 150 miles to the west! Needless to say we were quite surprised to find it growing in China. Beautiful intensely blue-green leaves. I am assigning it to this taxon for the time being as it most closely matches this subspecies as we know it. Will probably have yellow to apricot flowers. Outstanding foliage. 99/380 (Concatenans Group) CV#9523:RSBG (0\R1\4). Glowing sea-green leaves on this first collection of this taxon since it was originally collected by Frank Kingdon Ward. Grown from seed collected by Ken Cox on the Doshong La in SE Tibet. Low mounding habit and striking foliage, should have yellow to apricot flowers. citriniflorum var. citriniflorum Neriiflora Dwarf and compact evergreen shrubs. The leaves are dark green and smooth above with a thick grayish to brown indumentum beneath. The flowers (mid-spring) are bell-shaped and yellow to creamy yellow in color, sometimes with a faint pink flush. The unusually colored flowers, in combination with the attractive foliage and habit, make this a popular species with collectors. Difficult to propagate and rather finicky about cultural conditions, it is rarely offered and seldom seen outside of botanical collections. Native to the border regions of SE Tibet & NW Yunnan, China where it occurs in various alpine habitats from 13,000 to 16,000 ft. 70/143 BROD ((5\R2\2). Primrose yellow flowers. citriniflorum var. horaeum Neriiflora Dwarf shrubs to 5 ft. Flowers (April) are orange-red to carmine. Found among boulders and cliffs of alpine moorlands at 13,000 to 15,000 ft. China 76/139 F 21850:RBG (0) clementinae Taliensia Rounded compact evergreen shrubs with stout upright and somewhat stiff branches. The distinctive ovate to oval-lanceolate leaves have a thick spongy whitish indumentum on the lower surface. The foliage is often attractively glaucous blue-green on the upper surface. The flowers (mid-spring) are white to white flushed rose or rose, usually with reddish spots. One of the finest foliage plants in the genus which is unfortunately, very hard to propagate. Very slow-growing but long-lived in a well-drained soil with protection from the hot afternoon sun. Rarely offered, highly sought after species. Native to SW China (NW Yunnan & SW Sichuan) where it occurs from 11,000 to 14,000 ft. in moorland and along forest edges. 74/067 Greig-UBC (0) 83/028 DAW: TJ (0) 295sd1997 JN#352:RSBG ('10\R3\3). I am excited to offer these beautiful seedlings grown from the first reintroduction of this popular and rare species since 1937. A Jens Nielsen collection from 13,125 ft. near the 99 Dragon Pool, Lao Chun Shan, NW Yunnan, China. coelicum Neriiflora Small evergreen shrubs with dark shiny green obovate leaves. These have a thick pale brownish indumentum on the lower surface. The long bell-shaped flowers (mid-spring) are red to crimson. A beautiful foliage plant with attractive flowers. Rather difficult in cultivation and never a heavy bloomer but worth trying in a moist but very well drained soil in a cool but bright position. Quite rare in cultivation. Native to the NE Upper Burma/W Yunnan border region where it occurs in various montane habitats from 12,000 to 14,500 ft. A plant for the serious collector. 80/059 F#21830:Minterne (+5\R3\3). Flowers dark red on this 1955 Award of Merit clone. coeloneuron Taliensia' A new and somewhat puzzling introduction. As pictured in Sichuan Rhododendron of China this looks like a splendid new species with pink to purplish flowers and darker flecks. The foliage is said to be similar to that of R. wiltonii but with a bistrate versus a unistrate indumentum on the underside. From material now available however, I feel it is much closer to R. floribundum and should probably be placed in subsection Argyrophylla. Introductions from C Sichuan of what were thought to be this species have turned out to be just extreme forms of wiltonii. Recent collections of this species in N Guizhou match the description of coeloneuron perfectly and collections of what may be this species (or denudatum') in N Yunnan & S Sichuan are quite similar. Peter Cox feels that this species may be a link between the closely related subsections Argyrophylla and Taliensia as it shares distinguishing features of both groups. This is a beautiful foliage plant. Native to mixed forests from 4,000 to 7,500 ft. in S Sichuan, NE Yunnan & N Guizhou, China. 224sd95 PW#48:RSBG (0'\R1\4). Grown from seed collected wild in N Guizhou, China by Peter Wharton at 5,150 ft. This should be in every collection. NOTE: Comparable PW# collections of this species may be substituted if necessary. collettianum Pogonanthum Bushy shrubs to 3 ft. Flowers (May) are white, But buds are pink. Rare both in the wild and in cultivation. Native to steep rocky and stony slopes at 10,000 to 13,000 ft. Afghanistan, Pakistan 77/710 Wendelbo 8975-RBG (0) commonae Euvireya (Vireya) Tropical shrubs to 5 ft. Flowers (variable flowering time) are deep red to purplish crimson. As plants mature they can develop a truss of up to 6 flowers. Found on the island of New Guinea. Native on the edges of swamps or margins of Papuacedrus forest, exposed ridges, and in rocky areas from 6,500 to 13,000 ft. Indonesia, Papua New Guinea 79/035 PRA (+30) Red flowered, high elevation Vireya collected at Daulo Pass in New Guinea. concinnum Triflora Upright to compact growing evergreen shrubs. The lower surface of the ovate to oblong-elliptic leaves is gray to brown incolor due to the dense covering of scales. The flowers (mid-to late spring) are typically purple to reddish purple or ruby red but can also be pink, mauve or white, often with green or red spots. They are widely funnel-shaped with long exserted stamens. A floriferous, hardy and easy species in cultivation. Extremely variable in the wild, this species is found over a wide area of C China including Sichuan, Hubei, Shaanxi, Gansu & Henan. It occurs in forests and on cliffs from 5,000 to 14,500 ft. 64/177 (Benthamianum Group) RBGE (- 10\R1\6). Purple flowers with red-purple flecks. 64/180 (concinnum var. pseudoanthinum) WIS (-5).

China 83/153 WGP (+15) coryanum Argyrophylla Shrubs to 20 ft. Flowers (April-May) are creamy-white to white, with crimson flecks. Small but plentiful flowers in a loose truss. Native to forests and dense thickets from 11,000 to 14,000 ft. China 80/111 MM:Her (0) cowanianum Lepidota Deciduous shrubs to 8 ft. Flowers (May) are pink to purple- magenta to deep wine. Native to open slopes, on the edges of forests, or in deep gorges at 10,000 to 13,000 ft. Nepal 79/184 VVN: KWG (+5) crassifolium Vireya Tropical evergreen shrubs with large oblong to ovate rounded leaves. The attractive leaves have a heavily veined and puckered texture for a very distinctive appearance. The funnel-shaped flowers are bright red or sometimes pink and occur in large clusters. This vireya makes a unique and easily grown, attractive specimen. Native to Borneo where it is common and widespread from 3,900 to 7,200 ft. 87/041 RBGE (+32\R2\3).

China 65/497 GLE (0) Form with rose-lavender flowers. 69/106 Barto (0) cuprescens (possible hybrid of R. phaeochrysum and R. aganniphum) A shrub 3 to 15 ft. Flowers (March-April), are white, sometimes flushed pink, with crimson spots. Collected in Sichuan, China 79/146 Goteborg BG (0) cyanocarpum Thomsonia Stiffly branched and upright-growing evergreen shrubs or smal trees with smooth pale bark. The rounded leaves are blue-green and completely smooth. The bell-shaped flowers range in color from pure white to pink or rose and have dark nectar pouches at the base. This species is rather like a white or pink Chinese version of the well-known red-flowered R. thomsonii from the Himalayas. Very attractive foliage and one of the first species to bloom here every year, often in late February. Can be susceptible to powdery mildew though we have had little trouble here. Native only to the Cang Shan of W Yunnan, China where it is quite common from 10,000 to 13,000ft 77/731 ( syn. cyanocarpum var. eriphyllum) F 15570: WGP (0) This form is from seed collected in NW Yunnan by George Forrest during his 1917-19 expedition. 509sd1998 CCHH#8245:RSBG (- 5\R2\4).
