The genus Rhodamnia, founded by W. JACK (Malayan Miscellanies 1822) on the common Malayan R. cinerea, find its greatest development in the Australian and Papuan regions. DIELS (in LAUTERB., Beitr. Fl. Papuasien, V, ex ENGL., Bot. Jahrb. LVII, 360, 1922) recognizes five species, with a doubtful sixth, in New Guinea. I believe at least seven distinct species occur in Australia. In the present account of the Australian members of the genus, two new species are described, and a complete description of one, previously only known from sterile material is given.
