Notes
Similar to L. hexandra in which the keel of the lemma is pectinate-ciliate or at least clearly spinulose, whereas that of L. denudata shows merely an obscure scabridity or fine ciliolae under a lens. L. denudata also lacks the extensive rhizome system and ferociously scabrid leaf midrib of L. hexandra.
