翅萍婆属(Pterygota Schott&Endl.)云南梧桐科新记录属

Pterygota Schott & Endl.,A Genus of Family Sterculiaceae Newly Recorded in Yunnan Province

在云南铜壁关自然保护区大盈江河谷发现零星分布的梧桐科高大乔木翅萍婆(Pterygota alata(Roxb.)R.Brown),系云南新记录种,而翅萍婆属(PterygotaSchott&Endl.)为云南新记录属.该种是当地四树木—阿萨姆婆罗双季雨林的最上层树种之一,数量稀少,值得加强保护和进一步研究.

Pterygota alata （Roxb.） R. Brown was a newly recorded huge arboreal species in genus Pterygota Schott ＆ Endl. of family Sterculiaceae in Yunnan Province, which was found with scattered distribution in the Yingjiang valley in Tongbiguan Nature Reserve. Meanwhile the genus Pterygota Schott ＆ Endl. was also recorded for the first time in Yunnan Province. Pterygota alata （ Roxb. ） R. Brown is one of the tallest tree species to form the upper canopy of local Assamica monsoon forest. Because the population of this rare species is quite small, it deserves to be well protected and to be further studied.
