Leptochilus fluviatili s (Lauterb.) Liang Zhang & Li Bing Zhang, comb. nov.

Basionym: Polypodium fluviatile Lauterbach (1910: 507) View in CoL .

Colysis fluviatilis (Lauterb.) Ching (1933: 319) View in CoL , Leptochilus macrophyllus var. fluviatilis (Lauterb.) Nooteboom (1997: 289) View in CoL , Pleopeltis fluviatilis (Lauterb.) Alderwerelt (1917: 403) View in CoL .

Type:— MALAYSIA. Sarawak: ’Borneo. Zwischen Batu Babi und Lumowia’ , 10 July 1908, Winkler 2830 (holotype B-200087499!; isotype L-0051793!) .

Notes:—The species was treated as a variety of Leptochilus macrophyllus (1997: 286), or a synonym of L. pedunculatus

( Zhang & Nooteboom 2013). However, it differs from the latter two in having leaves strong dimorphic, fertile leaves 2– 3 times longer than sterile leaves, petioles the same length as or much longer than laminae, laminae thin-herbaceous.

Our recent molecular study of Leptochilus did not sample this species. Based on the distinctly dimorphic leaves and the distribution of the species, we assume that it is a member of the L. macrophyllus clade.
