中国兰科植物研究杂记

Additional Notes on Orchids from China

摘要:

报道了中国兰科植物一新记录种互生对叶兰[Neottia alternifolia（King & Pantl.）Szlach.]；并对紫婉石斛（Dendrobium transparens Wall. ex Lindl.）的形态特征、生境等进行了描述。紫婉石斛与兜唇石斛[Dendrobium aphyllum（Roxb.）C. E. Fischer]相似，区别在于唇瓣中央具深紫红色大斑块，唇瓣正面具柔毛； 互生对叶兰是鸟巢兰属自养类型种类中唯一具有两片互生叶的种类，极易同该属其他种类区分。

Abstract:

Based on field observation and specimen examination, two little known orchids, Dendrobium transparens Wall. ex Lindl. and Neottia alternifolia (King & Pantl.) Szlach., are documented first time in field in China. Dendrobium transparens is similar to Dendrobium aphyllum (Roxb.) C. E. Fischer, but it is easily distinguished from the latter by its lip having a large deep purplish red patch along its middle and pubescent adaxially; Neottia alternifolia (King & Pantl.) Szlach. is quite different from other species of Neottia Guettard by having two alternate leaves.
