Arisaema
''Arisaema'' is a large and diverse genus of the flowering plant family Araceae. The largest concentration of species is in China and Japan, with other species native other parts of southern Asia as well as eastern and central Africa, Mexico and eastern North America.〔(Kew World Checklist of Selected Plant Families )〕 Asiatic species are often called cobra lilies, while western species are often called jack-in-the-pulpit; both names refer to the distinctive appearance of the flower, which consists of an erect central spadix rising from a spathe.〔Govaerts, R. & Frodin, D.G. (2002). World Checklist and Bibliography of Araceae (and Acoraceae): 1-560. The Board of Trustees of the Royal Botanic Gardens, Kew. 〕〔(Flora China Vol. 23 Page 43, 天南星属 tian nan xing shu, ''Arisaema'' Martius, Flora. 14: 459. 1831. )〕〔(Flora of North America, Vol. 22, ''Arisaema'' Martius, Flora. 14: 459. 1831. )〕
==Classification and relationships==
The closest relatives of ''Arisaema'' appear to be ''Pinellia'' and ''Typhonium'' (although the latter as defined in 2004 seems to be paraphyletic, having given rise to ''Arisaema'' and other genera). One unusual trait shared by all ''Arisaema'' species, and not those of other genera, is the ''sex change''. ''Arisaema'' plants are typically male when small, and female or hermaphraditic when large, with a single plant capable of changing sex based on nutrition〔 and genetics, and perhaps changing sex several times during its long life (20 years or more).〔
