Title: Rhododendron subroseum sp. nov. and R. denudatum var. glabriovarium var. nov. (Ericaceae) from the Guizhou Province, China Authors: Chen, XA; Consaul, L; Huang, JY; Xie, H; Chen, X Author Full Names: Chen, Xiang; Consaul, Laurie; Huang, Jia-Yong; Xie, Hua; Chen, Xun Source: NORDIC JOURNAL OF BOTANY, 28 (4): 496-498 2010 Language: English Document Type: Article Abstract: One new species, Rhododendron subroseum Xiang Chen & Jiayong Huang, and one new variety, R. denudatum var. glabriovarium Xiang Chen & Xun Chen (Ericaceae), from the Guizhou Province, China are described and illustrated. Rhododendron subroseum is most similar to R. morii from which it differs mainly by having glandular branchlets, a subcordate leaf blade base and a mucronate leaf blade apex, a less floriferous inflorescence, a campanulate to broadly-campanulate corolla, and a glandular-hairy style. Rhododendron denudatum var. glabriovarium differs from R. denudatum var. denudatum mainly by having a glabrous ovary. Both of the new taxa are quite rare and therefore their protection is highly desired.
