Treatment

Leptochilus chingii Liang Zhang & Li Bing Zhang View in CoL , nom. nov.

≡ Colysis bonii Ching (1933: 322) View in CoL , Polypodium bonii (Ching) Christ (1934: 145) View in CoL .

Type :— VIETNAM. Province unknown: “Tonkin,” 9 January 1884, Bon 2395 (holotype P-0626870!, isotypes BM-001054009; P-0626869!) .

Notes:—When this species is transferred to Leptochilus , a new combination based on Colysis bonii Ching is blocked by Leptochilus bonii (Christ 1904: 610) C. Christensen (1906: 384) . The new epithet is in honor of the late professor Ren-Chang Ching, one of the best renowned pteridologists, who carried out some carefully morphological studies on Colysis . This fern is most close to Leptochilus pedunculatus ( Hooker & Greville 1827: TAB IV) Fraser-Jenkins (2008: 62), but differs from the latter in having leaves narrowly lanceolate, base shortly attenuate ( Ching 1933), petioles shorter than or as long as laminae.

This species was resolved in the Leptochilus ellipticus clade as sister to a clade containing four samples similar to L. pedunculatus ( Zhang et al., 2018) .
