holly gibbons

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 the Catawban yą́pą, from yą- tree + pą leaf. Another common name, cassina, was borrowed from Timucua (despite this, it usually refers to Ilex cassine). The Latin name comes from an incorrect belief by Europeans that the plant caused vomiting in certain ceremonies.
The plant was traditionally used by Native Americans to make an infusion containing caffeine. It is only one of two known plants endemic to North America that produce caffeine. The other is Ilex cassine, commonly known as dahoon holly. Yaupon is also widely used for landscaping in its native range.
