摘要

本文描述了在渝东北大巴山发现的一新种gastrochilusobovarifolius。该新种在形态上类似于G.affinis， G.balangshanensis和G.heminii，具有无毛和光滑的上毛。但可以通过独特的倒卵形叶片，较小的上毛和花的颜色来区分。基于核糖体内转录间隔区（nrITS）和4个叶绿体DNA片段（matK、psbA-trnH、psbM-trnD和trnL-F）的分子系统发育分析结果支持倒卵黄属天麻属。小叶豆属，与四川的八郎山小叶豆属亲缘关系最近。新种为常绿阔叶林树干附生植物。

Gastrochilusobovatifolius (Orchidaceae, Aeridinae), a new species from the Daba Mountains of Chongqing, China.

Gastrochilusobovatifolius, a new species discovered in the Dabashan of northeast Chongqing (China), is described and illustrated. The novelty morphologically resembles G.affinis, G.balangshanensis and G.heminii in having a glabrous and smooth epichile. but can be distinguished by the unique obovate shape of the leaves, smaller epichile, and flower color. The results of molecular phylogenetic analysis, based on nuclear ribosome internal transcribed spacer (nrITS) and four chloroplast DNA fragments (matK, psbA-trnH, psbM-trnD, and trnL-F) of 55 Gastrochilus species, support the inclusion of G.obovatifolius in G.sect.Microphylli, being most closely related to G.balangshanensis from Sichuan. The new species is a trunk epiphyte in evergreen broad-leaved forest.
