中国万代兰属(兰科)一新记录种——双色万代兰

Vanda bicolor,a newly recorded species of Vanda from China

该文报道了在中国西藏林芝地区墨脱县发现的中国兰科(Orchidaceae)万代兰属(Vanda W.Jones ex R.Br.)一新记录种——双色万代兰(Vanda bicolor Griff.)。双色万代兰与白柱万代兰(V.brunnea Rchb.f.)的形态较近似,但前者唇瓣中裂片正面粉色或黄绿色,不具纹,先端稍开裂,易与后者相区别。同时还描述了该新记录种的形态特征,并提供了彩色图版。该研究为兰科植物的研究提供了基础,对丰富我国兰科植物物种多样性具有一定意义。

Vanda bicolor Griff.of Orchidaceae found in Motuo County,Tibet of China,is reported as a newly recorded species from China.V.bicolor Griff.is similar to V.brunnea Rchb.f.in morphology,but it is easily distinguished from the latter by its pink or yellowish-green unstriped mid-lobe of lip,apex narrowly emarginate.Detailed morphological description and color plates of the newly recorded species are also provided.This study provides a basis for Orchidaceae plants research,and has certain significance to enrich its species diversity.
