The genus Arisaema contains approximately 180 species of deciduous or evergreen perennial herbs characterized by spathaceous inflorescence and one to several leaves that emerge from underground stems (Murata et al. 2018). Most Arisaema species are distributed in subtropical to cool temperate regions of Asia, although several are endemic to North America and tropical East Africa (Murata et al. 2018). The genus is particularly diverse in the Japanese Archipelago (Murata et al. 2018), where 53 species have been recorded.
