SWALLOWTHORN, or Sea-Buckthorn (Hippophaë). A genus of shrubs of the natural order Elæagnaceæ, natives of Europe. The commonest species (Hippophaë rhamnoides) is a spiny shrub often planted for ornament in sandy soil, especially near the sea. It is valued for its silvery leaves and yellow, acid, one-seeded berries, which, besides being attractive, are useful for sauces and jellies.
