Data from: Odontochilus napoensis sp. nov. (Orchidoideae: Orchidaceae) from southwestern Guangxi, China

Odontochilus napoensis, a new species from southwestern Guangxi, China, is described and illustrated. It is close to Odontochilus inabae (Hayata) T. P. Lin, but can be distinguished by its glabrous ovary, solitary flower, and 2.0–3.5 mm long filaments of flanges. It is also similar to O. nanlingensis (L. P. Siu & K. Y. Lang) Ormerod, but differs by the solitary, not resupinate flower, and light greenish–brown lateral sepals.

本文描述并图解了产自中国广西西南部的新物种那坡齿唇兰（Odontochilus napoensis）。该新种与因巴齿唇兰（Odontochilus inabae (Hayata) T. P. Lin）近缘，但可通过其无毛子房、单花以及长2.0–3.5毫米的褶边花丝与之区分。此外，它与南岭齿唇兰（O. nanlingensis (L. P. Siu & K. Y. Lang) Ormerod）亦近缘，但可通过其单花（不扭转）以及淡绿褐色侧萼片的特征加以区分。
