Anaphyllopsis is a genus of flowering plants in the family Araceae, native to northern South America.
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. 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 regards because it is the only known big genus in Araceae that is known to be found east of Wallace's line.
Lasia is a genus of flowering plants in the family Araceae, native to Asia and New Guinea. The genus contains only two known species, Lasia spinosa and Lasia concinna. Lasia was believed to be a monotypic genus until 1997 when a wild population of Lasia concinna was discovered in a farmer's paddy field in West Kalimantan, Indonesia. The farmer had been growing them for their edible young leaves. This species of Lasia had been known of previously only from a single specimen at the Bogor Botanic Gardens, formally described in 1920. Prior to 1997, the specimen was believed to have been a hybrid between Lasia spinosa and Cyrtosperma merkusii. The subsequent discovery by Hambali and Sizemore led to the realization that it was in fact a distinct species.
