High Quality Content by WIKIPEDIA articles! Cyrtosperma is a genus of flowering plants in the Araceae family that consists of approximately 12 species. The genus had gone through considerable taxonomic changes in the 1980s, and as a result is now considered to be endemic to only 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 found to be members of 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.
