Named after one of its discoverers, Melville Cook, this incredibly rare evergreen species was first collected during early botanical explorations of Cerro de Punta, Puerto Rico’s highest mountain. Cook’s holly grows as a small tree or shrub, with light-brown bark and hairless, green twigs. The leathery, elliptic leaves are arranged alternately on the stem, and have a shiny, dark-green upper surface, and a pale green lower surface (2) (3). No male flowers of this dioecious species have ever been observed, but the female flowers are small and white, and the fruit is a berry (1) (3) (4).
