The genus Leptochloa Beauv. (Poaceae, Eragrostideae) in Australia and Papua New Guinea.

Abstract

A taxonomic revision based on morphology is presented for 10 species constituting the genus Leptochloa in Australia (7 spp.) and Papua New Guinea (3 spp.). One species from Queensland, L. ligulata, is described as new. For the first time, L. chinensis (L.) Nees is reported from Papua New Guinea, and L. divaricatissima S. T. Blake from New South Wales. L. brownii C. E. Hubb., described from northern Australia, is considered to be conspecific with L. neesii (Thw.) Benth. from tropical Asia, and L. peacockii (Maid. & Betche) Domin described from New South Wales conspecific with L. decipiens (R. Br.) Stapf ex Maid, from Queensland.
