Philippines, Queensland, Solomon Is., and Sulawesi.

Moluccas, New Guinea, and Austrailia on the north-eastern Cape York Peninsula, from Cape York south, to the MacIllwraith Range, usually east of the Great Divide, and at altitudes below 600 meters. Caryota is a Caryotoid genus of 12 species occuring from India and Sri Lanka through south-east Asia to the Solomon Islands and Queensland. The only indigenous Australian species is not endemic, but has a wide distribution through parts of Malesia and Melanesia - C. rumphiana, the Australian population of which is refered to C. rumphiana var. australasica. Restricted to subequatorial monsoonal north-eastern Cape York Peninsula from Cape York south to the MacIllwraith Range, usually east of the Great Divide and at altitudes below 600 m. Commonly in lowland rainforest of varying soil types, i.e. sandy, basaltic, granitic and alluvial, on a range of aspects from flat to steep slopes. Also in semi-deciduous vine forests, broad-leaved swamp forests and brackish or fresh mangroves, contrary to previously published accounts (3). The present sp. occurs as infrequent to frequent scattered individuals or small to large groups, apparently never forming stands. It is particularly abundant in the Bamaga and Iron Range areas where it is a common but not dominant member of the rainforest communities. Pollenation is by insect, seed dispersal by flood, birds or mammals. In rainforest this species attains its maximum development, being smaller in all respects in vine forests (dry) or swamp-forests (wet).
