Ilex vomitoria Aiton. clade: Clade D4. Phen: Mar-May; Oct-Nov. Hab: Maritime forests, other dry sandy forests, shrublands, and disturbed areas. Dist: Widespread in the Southeastern United States, primarily on the Coastal Plain, from e. VA (from Northampton County south) south to c. peninsular FL and west to se. TX; Cuba; Mexico (CHP). In NC and VA, yaupon is nearly restricted to maritime habitats, on the barrier islands and in a narrow band on the mainland, in forests with substantial maritime influence, but is more general southwards in GA, FL, and the Gulf coast. I. vomitoria is increasingly popular as an ornamental shrub, and is persistent or establishing inland in areas outside its native distribution, especially in suburban woodlands. The species may have been substantially moved around by American Indians prior to European contact.
Origin/Endemic status: Native
Taxonomy Comments: I. vomitoria from the Deep South often has much smaller leaves than plants in the Atlantic Coastal Plain. The Chiapas populations have been accorded variety status as var. chiapensis Sharp; they may warrant specific rank or alternatively be nothing more than a pubescent form.
Other Comments: The tea produced from its leaves is increasingly appreciated.
