The rediscovery of Passiflora kwangtungensis Merr. (subgenus Decaloba supersection Disemma): a critically endangered Chinese endemic.

ABSTRACT: Passiflora kwangtungensis is a critically endangered Chinese species known from Guangxi, Guangdong, and Jiangxi Provinces. The species belongs to Passiflora subgenus Decaloba, supersection Disemma, section Octandranthus. Field observations decreased rapidly during the 1970s to 1980s, and it was suspected that this species might have been extirpated due to repeated deforestation events throughout southern China. In recent years, however, small isolated populations of this species have been rediscovered in Hunan Province, representing new locality records for Passiflora kwangtungensis. New herbarium collections, color photographs, and silica gel collections have provided an unexpected opportunity to examine the evolutionary significance of this species. The current study presents a revised m
