Cordiglottis longipedicellata (Orchidaceae), a New Species from Vietnam

Cordiglottis longipedicellata Joongku Lee, T.B. Tran & R.K. Choudhary, a new species of Orchidaceae from Vietnam is described and illustrated. It is morphologically most similar to C. pulverulenta, but differs in its floral morphology and in having a longer pedicel. Colour photographs, a table comparing the floral structure of the new species with supposedly closely allied species and a key are provided to facilitate species identification. The present paper is also the first report of the genus Cordiglottis in the Indo-Chinese region.

描述并图示了越南兰科（Orchidaceae）的一个新种——长梗心叶兰（Cordiglottis longipedicellata Joongku Lee, T.B. Tran & R.K. Choudhary）。它在形态上与粉心叶兰（C. pulverulenta）最为相似，但在花的形态上有所不同，且花梗更长。提供了彩色照片、一个比较新种与假定近缘种花结构的表格以及一个检索表，以便于物种鉴定。本文也是心叶兰属（Cordiglottis）在印度支那地区的首次报道。
