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]

Classification

Sabalites is a coryphoid leaf fossil common in the fossil record

Subfamily Coryphoideae is divided into 8 tribes: ^[3]

  • † Sabalites

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]
