Description originale : 226. Ageria Raf. (this name was used by Adanson for the G[enus].

Aquifolium, cal. 4fid persistens, cor. 4loba, stam. 4, stigma unicum sessile simplex. fl. sepe dioicis. - It will include nearly all the American sp. of Authors, which have a single stigma; but it varies in shape, and may serve to form subg.

Nom illégitime et superflu, car incluant explicitement à sa description Macoucoua Aubl. 1775, nom prioritaire et légitime qui aurait du être utilisé.
