Elæagnus

Elæagnus, a genus of Elæagnaceæ, the Oleaster family, of which there are about thirty-five species, all natives of north temperate countries. E. angustifolia, the Oleaster, sometimes called Wild Olive, is a small spiny tree of the Mediterranean region, hoary with stellate hairs, and is frequently planted for the sake of its silvery white foliage and its fragrant flowers. The Sea Buckthorn (q.v.), or Sallowthorn, is the only British species. The Silverberry, Shepherdia argentea, with pleasant fruit, and S. canadensis, have also been introduced to English parks from North America.
