Like the Zantedeschia rehmannii posted a couple days ago, Arisaema ciliatum is an aroid – a member of the family Araceae. The resemblance of the two species should be readily apparent. However, Zantedeschia is restricted to Africa, while the genus Arisaema can be found in Africa, North America (including Mexico) and temperate Asia. By far, the genus is most diverse in temperate Asia; Arisaema ciliatum itself is native to southern China.

The “Asian Flora” web site has extensive images of Arisaema ciliatum, or you can spend much time learning about the diversity of aroids on the site of the International Aroid Society.
