= Gastrochilus brevifimbriatus S. R. Yi (2010: 114).

Taxonomic discussion:— Gastrochilus brevifimbriatus was published as the new species by Yi et al. (2010), who morphologically compared it with G. acinacifolius Z.H. Tsi (1989: 25). Obviously, the authors lack the comprehensive recognition for genus of Gastrochilus and enough inspection of the specimen. After field investigation in type location of G. brevifimbriatus and comprehensive observe plant and flower characters using the fresh materials, we found that these morphological features were well accordance with the isotype of G. fargesii (Figure 8B) and the sketches of plant and epichile of labellum based on the isotype by Prof. Z.H. Tsi (Figure 8 B-1–2). However, only the specimens and simply draft of G. fargesii previously existed on which the protologue was based, which is the main reason for making the specimen misidentification and new species’ invalid publication. Therefore, we reduced it to the synonymy of G. fargesii and provide additional information for G. fargesii as below. Morphologically, it is similar to G. intermedius (Griffith ex Lindley 1858: 33) Kuntze (1891: 661), G. tianbaoensis Q. Liu & Y.H. Tan (Liu et al. 2016: 67), G. guangtungensis Z. H. Tsi (1996: 139), G. acinacifolius Z. H. Tsi (1989: 25), and G. linearifolius Z. H. Tsi & Garay (1996: 138) by having the repent stem and falcate leaves, but distinguished from latters by having broadly triangular epichile and galeate hypochile (Chen et al. 2009, Liu et al. 2016).
Distribution and ecology:— It is an epiphyte on tree trunks at altitudes from 670–750 m in a moist valley. Gastrochilus fargesii was observed flowering from July to August in the wild.
Etymology:— The specific epithet ‘ fargesii ’ commemorates Paul Guillaume Farges (1844–1912), a French missionary and plant collector based in Chongqing, China, from 1892 to 1912.
Specimens examined:— CHINA. Sichuan Province: Tschen Keou County, Moung Moung Ky près de Tchen Keou, 1600 m, 27 August 1893 P. G. Farges 1236 (Isotype: IBSC!, AMES!, K!, P!); Chongqing City: Nanchuan County, Houhe, Jinfo Montain, epiphytic on trunk, 720 m, 03 July 2017, Qiang Liu 457 (HITBC!); Chongqing City: Nanchuan County, Hou he, Jinfo Montain, on trunk, 680 m, 29 August 2007, Yi Si Rong 075631 (IMC!).
