ARACEAE

Araceae A.L. de Jussieu. Arum Family.

Key to Araceae

A family of about 100-110 genera and about 3000-4000 species, herbs and reduced aquatic herbs, cosmopolitan, but mostly tropical and subtropical. Circumscription of the Araceae is uncertain. Recent phylogenetic studies (Lee et al. 2019) show four distinctive and major clades in what is now (APG IV 2016) generally considered to comprise Araceae s.l., with the four clades generally now treated as subfamilies: Gymnostachydoideae, Orontioideae, Lemnoideae, and Aroideae. A strong case exists for treating these morphologically and molecularly disparate clades at family rank, as has variably been done traditionally.
