Nyssa yunnanensis is a species of tree in the Nyssa genus. It is a dioecious tree (meaning that it has distinct male and female individual organisms) reaching 25–30 m (82–98 ft) in height. This flowering canopy tree inhabits mountainous tropical bogs and marshes.[2]
Because of habitat loss and logging, this species is critically endangered in the IUCN Red List of Threatened Species.[1] It now exists only in the vicinity of Xishuangbanna, which is located in Jinghong County, Yunnan Province, China.[1][3] Only eight individual trees and two populations have been found in the wild, and 1999 this species has been listed among China's national Class I protection species and also among 120 PSESP (Plant Species with Extremely Small Populations) in the Implementation Plan of Rescuing and Conserving China's Plant Species with Extremely Small Populations (PSESP)[4] and as critically endangered in the Threatened Species List of China's Higher Plants. To facilitate future conservation biology studies a reference genome was sequenced, creating a 1475 Mb assembly with 39,803 protein-coding genes.[5] DNA was collected from a voucher specimen from Ruili Botanical Garden and stored in the China National GeneBank herbarium.
