Ilex vomitoria

Ilex vomitoria (Yaupon Holly, Yaupon, or Cassina; the latter shared with Ilex cassine), is a species of holly native to southeastern North America, occurring in United States from Maryland south to Florida and west to Oklahoma (only in the extreme southeast)[1] and Texas, and in Mexico in Chiapas.[2]

It is an evergreen shrub or small tree reaching 5-9 m tall, with smooth, light gray bark and slender, hairy shoots. The leaves are alternate, ovate to elliptical with a rounded apex and crenate or coarsely serrated margin, 1-4.5 cm long and 1-2 cm broad, glossy dark green above, slightly paler below. The flowers are 5–5.5 mm diameter, with a white four-lobed corolla. The fruit is a small round, shiny, and red (occasionally yellow) drupe 4-6 mm diameter containing four pits, which are dispersed by birds eating the fruit. The species may be distinguished from the similar Ilex cassine by its smaller leaves with a rounded, not acute apex.[3][4][5][1][6]
