First Record Of The Sino-Himalayan Species Deyeuxia Himalaica In Yunnan Province, SW China, And Three New Combinations In Calamagrostis (Poaceae, Agrostidinae)

As a result of recent studies of worldwide Agrostidinae, Deyeuxia gaoligongensis Paszko, D. himalaica Liou ex W. L. Chen and D. sorengii Paszko & W. L. Chen are here recombined as Calamagrostis gaoligongensis comb. nov., C. himalaica comb. nov. and C. sorengii comb. nov., respectively, and the first record of the Sino-Himalayan species C. himalaica from Yunnan Province, southwestern China, is reported. Calamagrostis himalaica occurs primarily in southeast Xizang, southwestern China, with a single locality recorded recently in Kachin State, Myanmar (Burma). A map with all known geographic records of C. himalaica and an image of the newly identified specimen are presented.
