A small tree, attaining in Ireland 4o feet in height and 10 feet or more in girth, 
usually a shrub in the Mediterranean region. Bark rough, brownish-red, more or 
less fissured, and only rarely scaling off in part. Young branchlets reddish or green, 
covered with gland-tipped hairs, which persist in the second year ; older branchlets 
brown, rough, slightly fissuring on the surface. Buds minute, reddish; scales 
imbricated, ovate, acute, ciliate. Leaves 2 to 4 inches long by 1 to 2 inches broad, 
very variable in shape, oblong, oblong-lanceolate, elliptic, or ovate, acute at the apex, 
tapering at the base; upper surface dark-green, glabrous and shining ; lower surface 
pale-green, glabrous, with prominent midrib and inconspicuous pinnate-reticulate 
venation; margin serrate or biserrate, the serrations acute or rounded. Petioles 
short, about inch long, glandular-pubescent. 
Flowers appearing in autumn, inodorous, in short drooping glabrous terminal 
panicles. Calyx-lobes minute, triangular. Corolla usually white, rarely pinkish, 
urceolate, with rounded ciliated teeth; ovary glabrous. Fruit ripening in the follow- 
ing autumn, at the same time as the appearance of the flowers of the succeeding 
year; a stalked berry, pendulous, sub-globose, # inch in diameter, orange-scarlet, 
densely covered with minute pyramidal spine-like excrescences, edible, superficially 
resembling a strawberry, but entirely different in structure. 
Seedling.—Cotyledons two, raised above ground on a short caulicle, oval, 
rounded at the apex, abruptly narrowed at the base into a flat petiole, entire, ¢ inch 
long, dull-green above, pale-green beneath. Young stem reddish, with short 
glandular hairs; primary leaves alternate, minute, oval or obovate, serrate and 
minutely glandular-pubescent in margin; tap-root about 2 or 3 inches long.
