“…Gastrochilus D.Don (Orchidaceae, Epidendroideae; Don 1825) is diagnosed by a subdivided labellum with a recurved epichile and a saccate hypochile attached to the column at the base and two subglobose pollinia attached to a slender and filiform stipe (Tsi 1999;Pridgeon et al 2014). The genus comprises more than 70 accepted species, most of which are distributed in Southeast Asia (Kumar et al 2014;Liu et al 2016Liu et al , 2019Liu and Gao 2018;Rao et al 2019;Govaerts et al 2021;Nguyen et al 2021;Zhou et al 2021a, b;Zhang et al 2022). Liu et al (2019) first constructed the phylogenetic relationships of Gastrochilus and divided them into five clades.…”

Gastrochilus heminii (Orchidaceae), a new orchid species from Sichuan Province, Southwest China, is described and illustrated. It morphologically resembles G. affinis and G. yei, but differs markedly from the former in having a thinner and slightly rolled downwards reniform epichile and the central thickened purple-red mat with irregular folds (vs. subtriangular epichile curves upwards, with 2 thick, brown to purplish-brown median ridges from base to apex), and can be clearly distinguished from the latter by having reniform epichile with lobed apex and subconical hypochile with bilobed apex that splits into two conical protrusions (vs. semi-rounded epichile not lobed and subconical hypochile not bilobed). 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 36 Gastrochilus species showed that G. heminii was closely related to G. affinis and G. distichus.

Gastrochilus wolongensis (Orchidaceae), a new orchid species from Sichuan Province, Southwest China, is described and illustrated. It morphologically resembles G. sinensis , but differs markedly from the latter in having black-purple stripes (vs. purplish-red spots) on the adaxial side of the petals and sepals, a reniform epichile densely covered with long papillate hairs (vs. sparsely pubescent) with purplish-red spots (vs. unspotted), and outside the sac of the hypochile with purplish-red stripes (vs. purplish-red spotted). The molecular phylogenetic analysis based on nuclear ribosome internal transcribed spacer (nrITS) and four chloroplast DNA fragments ( mat K, psb A- trn H, psb M- trn D, and trn L-F) of 36 Gastrochilus species showed that G. wolongensis was closely related to G. ciliaris and G. formosanus .
