Abstract
Two new dwarf species of Diplacrum are described from tropical Australia: Diplacrum blakei K.L.Wilson & R.L.Barrett and D. latzii K.L.Wilson & R.L.Barrett. Diplacrum is the only genus in Cyperaceae tribe Bisboeckelereae occurring in Australia. Historically, it has been confused with Scleria (Tribe Sclerieae). Descriptions are provided for all four Australian species, as well as a generic description and a key to Australian and three additional Malesian and South-East Asian species. Brief comments are made about the species in Africa, the tropical Americas and India.
Keywords: Africa, Malesia, Naikia, Northern Territory, Papua New Guinea, plant taxonomy, Pteroscleria, Queensland, Scleria, sedges, Sphaeropus, systematics, tropical Americas, Western Australia.
