Coryphoideae

The Coryphoideae is one of five subfamilies in the palm family, Arecaceae. It contains all of the genera with palmate leaves, excepting "Mauritia", "Mauritiella" and "Lepidocaryum," all of subfamily Calamoideae, tribe Lepidocaryeae, subtribe Mauritiinae. However, all Coryphoid palm leaves have induplicate (V-shaped) leaf folds (excepting "Guihaia"), while Calamoid palms have reduplicate (inverted V-shaped) leaf folds. Pinnate leaves do occur in Coryphoideae, in "Phoenix", "Arenga", "Wallichia" and bipinnate in "Caryota".
Classification.
Subfamily Coryphoideae is divided into 8 tribes:
The genus "Sabinaria" was discovered and described after the classification used here was published, but its morphology clearly places it in tribe Cryosophileae. The genus "Saribus" was split from "Livistona", while "Lanonia" was split from "Licuala", also after publication. Tribe Trachycarpeae was initially described as tribe 'Livistoneae', but the name Trachycarpeae has priority.
Also "Uhlia" is an extinct genus described from permineralized remains recovered from the Ypresian Princeton Chert in British Columbia, Canada.
