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]

The genus Sabinaria was discovered and described after the classification used here^[3]^[4] was published, but its morphology clearly places it in tribe Cryosophileae.^[7] The genus Saribus was split from Livistona,^[8] while Lanonia was split from Licuala,^[9] also after publication. Tribe Trachycarpeae was initially described as tribe 'Livistoneae',^[3] but the name Trachycarpeae has priority.^[4] Also Uhlia is an extinct genus described from permineralized remains recovered from the Ypresian Princeton Chert in British Columbia, Canada.^[10]
