摘要:

该文报道了在广西七冲国家级自然保护区发现的中国大陆兰科(Orchidaceae)天麻属(Gastrodia R. Brown)一新记录种——乌来天麻(G. uraiensis T. C. Hsu & C. M. Kuo)。乌来天麻形态较近似于春天麻(G. fontinalis T. P. Lin),但乌来天麻的花序、花被筒较短,唇盘中部具4条纵向脊,脊向舌状先端延伸、合并成更高的2条,易与春天麻相区别。同时,还描述了新记录种的形态特征,提供了彩色图版,并讨论了此次新发现的生物地理学意义。

Abstract:

Gastrodia uraiensis T. C. Hsu & C. M. Kuo of Orchidaceae was found in Qichong National Nature Reserve of Guangxi as a newly recorded species from Mainland, China. G. uraiensis T. C. Hsu & C. M. Kuo is similar to G. fontinalis T. P. Lin in morphology, but it is easily distinguished from the latter by its inflorescence shorter, perianth tube shorter, lip with four ridges elevated from central portion of the disc, ridges united into two higher ridges toward apex. Detailed morphological description and color photos of the newly recorded species are provided, and biogeographic significance of the discovery is discussed.

Key words: Gastrodia uraiensis, Gastrodia, Orchidaceae, new record, Mainland of China
