SEA-BUCKTHORN: A genus of the tetrandria order, belonging to the dioecia clas of plants; and in the natural method ranking under the 16th order, Calyciflora. The male calyx is bipartite; there is no corolla; the female calyx is bifid; there is no corolla; there is one style, and a monoppermous berry.

Species. 1. The rhamnoides hath a shrubby stem, branching irregularly eight or ten feet high, having a dark brown bark. It is armed with a few thorns; hath spear-shaped, narrow, fleshy leaves, of a dark green above, and hoary underneath. 2. The canadensis hath a shrubby brown stem, branching eight or ten feet high, with oval leaves, and male and female flowers on different plants.

Culture, &c. Both these species are very hardy, and may be propagated in abundance by suckers from the roots, by layers, and by cuttings of their young shoots. They are retained in gardens on account of their two-coloured leaves in summer; and in winter, on account of the appearance of the young shoots, which are covered with turgid, irregular, fleshy buds. Goats, sheep, and horses, eat the first species; cows refuse it.
