HIPOPHAE, SEA-BUCKTHORN; a genus of the tetrandria order, belonging to the diœcia class of plants.
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, sessile 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, scaly buds. Goats, sheep, and horses, eat the first species; cows refuse it.
