Ilex vomitoria, commonly known as yaupon or yaupon holly, is a species of holly that is native to southeastern North America. The word yaupon was derived from its Catawban name, yopún, which is a diminutive form of the word yop, meaning "tree". Another common name, cassina, was borrowed from the Timucua language (despite this, it usually refers to Ilex cassine).
