In Malesia and Australia there are nine species of Oryza L. (Gramineae). Oryza meyeriana (Zoll. & Mor.) Baillon has two varieties. Oryza schlechteri Pilg. is only known from Irian Jaya (Indonesian New Guinea). Oryza australiensis Dom. and O. meridionalis Ng are endemic to Australia. The numerous forms of O. sativa L. have not been treated. Oryza rufipogon Griff., supposedly the wild progenitor of O. sativa, is considered as a distinct species. The name for the subfamily Oryzoideae is validated.
