The sea-buckthorns deciduous shrubs in the genus Hippophae, family Elaeagnaceae. The name sea-buckthorn is hyphenated here to avoid confusion with the buckthorns (Rhamnus, family Rhamnaceae). It is also referred to as sandthorn, sallowthorn, or seaberry. There are considered to be seven species, two of them probably of hybrid origin, native over a wide area of Europe and Asia. The common sea-buckthorn (Hippophae rhamnoides) is by far the most widespread of the species in the genus, with the ranges of its eight subspecies extending from the Atlantic coasts of Europe right across to northwestern China.
