Caryoteae is a tribe in the palm family Arecaceae,[1][2] distributed across Southeast Asia, from southern India and Sri Lanka east to Vanuatu and northernmost Queensland, Australia . It was long considered a member of subfamily Arecoideae on the basis of its inflorescences, which resemble those of tribe Iriarteeae, and the flowers arranged in triads (two male flowers with a central female flower), which are common across Arecoideae.[3] However, phylogenetic studies based on DNA repeatedly link Caryoteae to subfamily Coryphoideae. Caryoteae do have leaves with induplicate folds, a feature found in most Coryphoid palms, but unlike most Coryphoideae, the leaves are pinnate (Arenga, Wallichia) or bipinnate (Caryota).[4][5] Phoenix is the only other Coryphoid genus with induplicate, pinnate leaves.[5]
