摘要
报道了中国兰科植物四个新记录种,反瓣叉柱兰(Cheirostylis thailandica),短茎对叶兰(Listerabrevi-caulis),凹唇石仙桃(Pholidota recurva),绿花大苞兰(Sunipia annamensis)。短茎对叶兰(Listera brevicaulis)二枚叶贴地着生,唇瓣先端二裂,裂片下翻并靠合;凹唇石仙桃(Pholidota recurva)的假鳞茎圆柱形,首尾相连,花偏向一侧,花序在中部向下弯,唇瓣前端略凹陷;绿花大苞兰(Sunipia annamensis)的花序长于叶,唇瓣心形,肉质,边缘向上翻卷。
Cheirostylis thailandica, listera brevicaulis, Pholidota recurva and Suaipia annamensis are recorded for the first time in China. Cheirostylis thailaztdica is characterized by its petals with recurred tips and non-adnate to dorsal sepal, two green spots at the base of epichile, non-fringed lobules and stylids slightly longer than rostellum arms. Listera brevicaulis differs from all its allies by having very short stem with its leaves prostrate on the ground, bilobed lip with its lobelets recurved and meeting underneath. Pholidota recurva is characterized by its cylindrical and superposed internedes, secund flowers and emarginated-tipped lip. Sanipia annamensis is easily distinguished from its relatives by its inflorescence much longer than leaves and fleshy, broadly cordate lip with upcurved edges.
