|Ilex vomitoria subsp. var.||Yaupon Holly, casseena|
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) and Texas, and in Mexico in Chiapas.
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 or 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.
