Basionym: Colysis evrardii Tardieu (1940: 372) . Type :— VIETNAM . Lam Dong Province : Dalat , 17 December 1924 , Evrard 2250 ( lectotype P-00709509!; here designated ) . Notes:—When Colysis evrardii was published, both Evrard 2250 and Evrard 1921 were cited without designating its type . This fern is similar to Leptochilus decurrens Blume (1828: 206) , but differs from the latter in having narrower sterile leaves and wider fertile leaves. It is also similar to Colysis diversifolia W.M. Zhu (1979: 93) and Leptochilus ×beddomei ( Manickam & Irudayaraj 1997: 267 ) X.C. Zhang & Nooteboom (2013: 834) in having narrowly lanceolate fertile leaves with interrupted sori. However, the large leaves of L. evrardii are sterile, while the large leaves of Colysis diversifolia and Leptochilus ×beddomei often have irregularly scattered sori. The species was resolved as a member of the Colysis clade ( Zhang et al. 2018 ), and is most closely related to L. decurrens .
