Key to Ilex

A genus of 400-500 species, mostly trees and shrubs, cosmopolitan and widespread in tropical and temperate areas, especially Asia and America. The genus Nemopanthus is deeply embedded in the phylogenetic tree of Ilex and is clearly best subsumed into it (Manen, Boulter, & Naciri-Graven 2002; Yao et al. 2021; Yang et al. 2023). Sectional classification follows Yang et al. (2023).

ID notes: Some of our species can be superficially similar to various shrubs and trees of the Rosaceae, in their deciduous, alternate, toothed leaves borne on spur shoots.
