Cyrtosperma is a genus of flowering plants in the family Araceae. The genus went through considerable taxonomic changes in the 1980s, and as a result is now considered to be native only to Southeast Asia and some Pacific islands.[1][2] Previously, the genus was believed to be widespread from Asia to Africa and South America, but the African and South American species were subsequently moved into separate genera. Cyrtosperma is now known to be most prominent in New Guinea. The genus Cyrtosperma is unique in this regard because it is the only known big genus in Araceae that is known to be found east of Wallace's line.[3][4]
Cyrtosperma merkusii, or pulaka, is grown as a root crop in Oceania.
