The Coryphoideae is one of five subfamilies in the palm family, Arecaceae.[2][3][4] It contains all of the genera with palmate leaves, excepting Mauritia, Mauritiella and Lepidocaryum, all of subfamily Calamoideae, tribe Lepidocaryeae, subtribe Mauritiinae.[5][4][3] However, all Coryphoid palm leaves have induplicate (V-shaped) leaf folds (excepting Guihaia), while Calamoid palms have reduplicate (inverted V-shaped) leaf folds.[4] Pinnate leaves do occur in Coryphoideae, in Phoenix, Arenga, Wallichia and bipinnate in Caryota.
Coryphoids are well-represented in the fossil record from the Late Cretaceous (Campanian) onwards, primarily due to the presence of the form genus Sabalites.[6]
