AB -The newly discovered orchid, <i>Gastrochilus wenchuanensis</i> (Aeridinae, Orchidaceae), found in Wenchuan, Sichuan of China, is described here based on the data of its morphology, phenology, ecology and distribution. This entity bears resemblance to <i>G. formosanus, G. wolongensis, G. nanchuanensis, G. sinensis, G. minjiangensis</i> and <i>G. armeniacus</i>, but can be distinguished by a distinctive vein on both the petals and sepals, as well as an epichile and hypochile that are devoid of spots or stripes. The molecular phylogenetic analysis, based on the nuclear ribosomal internal transcribed spacer (nrITS) and four plastid regions (atpI, matK, psbA, and trnL-F), supports the conclusion that <i>Gastrochilus wenchuanensis</i> is a new species and is sister to <i>G. formosanus</i>.
