Notes:—This species is endemic to southern Yunnan, and was often treated as a synonym or a variety of Leptochilus ellipticus (e.g., Nooteboom, 1997; Zhang & Nooteboom, 2013), which is not supported by our phylogenetic analyses ( Zhang et al., 2018). This fern is most similar to L. pothifolius (Buchanan-Hamilton ex D. Don 1825: 13) Fraser-Jenkins (2008: 181) by having 1–3(4) pairs of large lobes, lobes up to 4 cm wide, but differs from the latter in having narrowly winged rachis.

The species was resolved as an isolated clade in Leptochilus . Its sister relationship with the Colysis clade was poorly supported ( Zhang et al. 2018).
