This combination was previously published by X. C. Zhang (Lycophytes Ferns China, 654. 2012) but not validly so because Colysis leveillei was cited instead of the basionym, Selliguea leveillei (Melbourne Code, Art. 41.5).

Leptochilus leveillei is very similar to L. wrightii but without paraphyses.
