A Newly Recorded Species, Dendrobium okinawense of Dendrobium (Orchidaceae) in Taiwan

A newly recorded species, Dendrobium okinawense Hatusima & Ida, in Taiwan is described and illustrated. This species is rare and endemic to Ryukyu Islands. We recently found it in the mountains of along the coast in southeast of Taiwan. Although the flower of D. okinawense is somewhat structurally similar to that of D. moniliforme, they are evidently different from each other in floral dimensions, petals, lip shapes and floral color.

本文记述并图示了台湾新记录物种冲绳石斛（Dendrobium okinawense Hatusima & Ida）。该物种较为罕见，为琉球群岛特有种。我们近期在台湾东南部沿海山区发现了该物种。尽管冲绳石斛的花在结构上与念珠石斛（Dendrobium moniliforme）存在一定相似性，但二者在花的尺寸、花瓣形态、唇瓣形状以及花色上均存在显著差异。
