虽然Gastrochilus Don（1825：32）是一个小属，但其属间和种间关系仍不清楚（Seidenfaden 1988，Tsi 1996，Pridgeon et al . 2014，Zou et al . 2015年）的报告。它包括64种，分布于中国、印度和斯里兰卡，通过东亚和日本南部到印度尼西亚和菲律宾（Kumar et al . 2014，Govaerts et al . 2015，Raskoti 2016）。中国是该属物种多样性的中心，共有39种，其中19种被认为是特有的（Tsi 1999，Chen et al . 2009，Yi et al . 2012，Kumar et al . 2014年）。在云南东南部的野外调查中，发现了两种罕见的本属植物。在进行了全面的文献和植物标本的审查，这两个种被确定为G。Gastrochilus Don（1825：32），其特征在于粗壮茎与大茎生叶。一个是中国新记录，另一个是新种。
Although Gastrochilus Don (1825:32) is a small genus, its generic and interspecific relationships are still not well understood (Seidenfaden1988, Tsi 1996, Pridgeon et al . 2014, Zou et al . 2015). It comprises 64 species collectively distributed from China, India and Sri Lanka through eastern Asia and southern Japan to Indonesia and the Philippines (Kumar et al . 2014, Govaerts et al . 2015, Raskoti 2016). China is the centre of species diversity for the genus, which contains 39 species, 19 of which are believed to be endemic (Tsi 1999, Chen et al . 2009, Yi et al . 2012, Kumar et al . 2014). During our field investigation in southeastern Yunnan, two unusual species of this genus were discovered. After undertaking a comprehensive literature and herbarium review, these two species were identified as G. sect. Gastrochilus Don (1825: 32), which is characterized by stout stem with large cauline leaves. One is a new record for China, and the other is the new species.
