R. glanduliferum RSF 245/sd/1995, collection # PW041 Blomstrede i starten af juli 2011.

R. glanduliferum (Fortunea) Et ny introduceret arter, som danner store afrundede buske. Bladene kan være meget store (30-36 cm i længen) De er elliptisk til aflang-lancetformede. Nyvæksten er tæt kirtelbelagt. De duftende hvide blomster er tragt.klokkeformede med 6-7 lapper og er også tæt dækket med kirtler på ydersiden. Blomsterne ligner dem hos R. auriculatum. Denne art er kendt fra kun tre steder i NØ Yunnan (og tilstødende N-Guizhou) hvor den vokser i kratområder fra 2300 til 3000 m. Kræver en del beskyttelse for senfrost. Allan Clark har insamlet frø R. glanduliferum aff. AC1041,AC1043 Zhaotang, Maushan, Lahhua 2000-3000m, men det er arten R. qiaojiense

R. glanduliferum RSF 245/sd/1995, collection # PW041 Blomstrede i starten af juli 2011. En anden type er RSF 503/sdl 1996 fra Steve Hootman collection (SEH174) som blomstrer tidligt i september


Steven Hootmann's comments:
The SEH#174 glanduliferum (the Yunnan or "true" form ie. it is the form that was originally named as such) is quite a bit later than the forms from Guizhou which are generally under Peter Wharton's PW #'s (it is not recorded by the Chinese as being native to Guizhou). Those are in full flower right now at the RSBG, both pink and white, while the Yunnan plants may not flower until early Sept. depending upon the year. A very confusing group and I think that Chinese botanists may have recently named the Guizhou form as a new species, it is quite different in some ways and yet very similar, if you know what I mean. I have seen many populations in several parts of Guizhou and it is indeed a very confusing complex. Now we will have the Jens Nielsen collection of the closely related magniflorum, also from Guizhou, as well as my collection of faithiae from Guangxi last year to make it all even more confusing?
They are all great plants no matter how they are split out. You should not have to wait too long for flowers on either form, they should bloom at around 10 or 12 years of age.
