中国兰科植物一新种——南迦巴瓦虎头兰

Cymbidium namchabarwaense(Orchidaceae;Epidendroideae),A New Species from Xizang,China

报道了中国西藏兰属植物一新种——南迦巴瓦虎头兰Cymbidium namchabarwaense,该种植株大,花量多,体态近似于西藏虎头兰,花则与长叶兰和黄蝉兰近似,例如萼片和花瓣均具褐色或红棕色条纹和斑点。但与长叶兰不同的是,该种花序很长,具十余朵花,唇瓣边缘全缘,蕊柱光滑无毛;该种与黄蝉兰的区别在于前者唇盘具乳突状腺毛,而后者唇瓣具长柔毛。该文提供详细的物种描述和解剖图版,以及模式标本、生境和物候等信息。该新种的发现扩充了兰属植物的记录,为今后中国兰属植物的栽培驯化以及培育园艺品种提供了新资料。

This study reports the discovery of a new species of Cymbidium in the genus from Xizang,China,named Cymbidium namchabarwaense.This newly identified species is characterized by its large plant size and abundant flowers.Its overall appearance resembles that of C.tracyanum,while its flowers exhibit similarities to C.erythraeum and C.iridioides,particularly in the presence of brown or reddish-brown stripes and spots on the sepals and petals.However,unlike C.erythraeum,this species has longer inflorescence,with more than ten flowers,its lip has an entire margin,and the column are smooth and hairless.The difference between this species and C.iridioides is that the former has papillaceous glandular hair,while the latter has villous.This paper provides detailed species descriptions and pictures,as well as information on type specimens,habitats,and phenology.The discovery of this new species has expanded the records of orchids and provided new information for the cultivation and domestication of Cymbidium and the cultivation of horticultural varieties in China.
