Ilex opaca Ait.

An evergreen tree sometimes 40 to 50 ft high in the wild, with a trunk 6 to 9 ft in girth, resembling the common holly in habit; young shoots minutely downy. Leaves dull green above, yellow-green beneath, oval, tapered more abruptly at the base than at the spine-tipped apex, 11⁄2 to 31⁄2 in. long, half as wide, the margins armed with broad, spine-tipped teeth, which tend to disappear from the uppermost leaves of adult specimens; stalk grooved, 1⁄4 to 1⁄2 in. long, minutely downy. Male flowers in three- to nine-flowered, slender-stalked cymes; females usually solitary; all small, dull white; calyx-lobes edged with minute hairs. Fruits red, round, 1⁄4 in. diameter, on a stalk about as long.

Native of the eastern and central United States; introduced in 1744. In gardens this species is only likely to be confused with the Himalayan I. dipyrena, which has similarly opaque, evergreen foliage, but that species has longer narrow leaves with shorter stalks, and much shorter-stalked, more congested flower-clusters. The fruit also is larger. I. opaca sometimes bears fruit very freely in this country, and is then ornamental, but it is never so attractive as our common native species. There is a fine specimen of this species at Kew near the south end of the Holly Avenue.
