Coelogyne putaoensis (Orchidaceae), a new species from Myanmar
The new species is named after Putao, the northernmost town of Myanmar near which it was discovered in a vast area of unspoiled mountain forest.
Coelogyne Lindl. is a genus of about 200 species, distributed from South and Southeast Asia into the Pacific as far east as Fiji and Samoa. Around 45 species of Coelogyne have been recorded from Myanmar.
Associate professor Xiaohua JIN, researcher of Institute of Botany,CAS, during their fieldwork in Hponkanrazi Wildlife Sanctuary, Putao, Kachin State, Myanmar, in June 2016, discovered a new species of Coelogyne, named Coelogyne putaoensis. It is morphologically similar to C. taronensis and C. weixiensis, presumably its nearest relatives. An identification key and colour photographs are provided. A preliminary risk-of-extinction assessment according to the IUCN Red List categories and criteria is given for the new species.
The new species is named after Putao, the northernmost town of Myanmar near which it was discovered in a vast area of unspoiled mountain forest. It was presented as " Coelogyne putaoensis (Orchidaceae), a new species from Myanmar", and published in the PhytoKeys.
Coelogyne putaoensis is a predominantly epiphytic species that grows on moss-covered branches and tree trunks, sometimes also on rocks, in humid, broad-leaved, evergreen, montane forest, from 2500 to 3100 m elevation. At present, C. putaoensis is only known from the type locality.
