Hippophae Rhamnoides belongs to the family of eleagnaceae, (it is sometimes spelled Hippophaë Rhamnoid).
Synonyms : Elaeagnus Rhamnoides (L.) A. Nelson, Hippophae Angustifolia Lodd., H. Littoralis Salisb., H. Rhamnoideum Saint-Lager, H. Sibirica Lodd., H. Stourdziana Szabó, Ossyris Rhamnoides Scop., Rhamnoides Hippophae Moench.

Linné has taken up a name of Pliny1 and Dioscoride, Hippophaes, which designates a thorny euphorb, Euphorbia acanthothamnos. It was for him a vague allusion to the presence of thorns. In Greek, among the plants "which have leaves in addition to their thorns", Theophrastus (HP. VI) quotes ἰππόφεως - Hippopheôs and φέως - Pheôs, which is the spine pimplernelle , Sarcopoterium spinosum2. In other words, ἰππόφεως - Hippopheôs is the "great spine pimpenelle", where ἵππος - horse is a simple augmentative.3 The epithet Rhamnoides means " False nerprun " (Rhamnus).

The vernacular names of the species mostly refer to its morphology or in the middle of the reception : Argasse, Grisset, shiny spine, Maranto spine, thorny willow, false nerprun, marine bourdaine, olivier or pineapple Siberia. In other languages  : Sea-Buckthorn in English, Sanddorn in German, Espino Amarillo in Spanish and 沙棘 属 in Mandarin literally means genre, Spine and sand. The phonetic proximity between Archman and Arbousier (Arbutus UNDO) makes confusion between the two plants particularly frequent.

Very thorny woody, at the bushy port, from 1 to 5 meters (noted up to 18 m in certain flora, near breakdowns Dunes for example, it easily reaches About ten meters while exposed to the wind, the plant retains lesser proportions), nanophanérophyte (cf. classification of raunk) and Caducifolia. Its longevity extends up to 80 years. The Dioic plant is pollinated by insects and dispersed by birds. It is a pioneer, Heliophile.

The leaves, deciduous, alternate, simple, are very narrow and have a single rib. The Petiole is very short. The Limbe is green on the upper side and silver gray on the underside. The flowers, a beetles, very small, are greenish and appear in April, before the leaves. The fruits, of ovoid shape, are complex (False Drupes), made up of an Akène surrounded by a fleshy part resulting from the transformation of floral receptacle. Globular, they are yellow or orange at maturity (around the month of September) and measure from 6 to 8 mm in diameter.

Shrubs generally bear fruit after three years and give maximum yields after seven to eight years. The male feet flourish a little earlier than the females and for a period of 6 to 12 days ; 12 to 15 weeks are necessary until the full maturity of the fruit.

Food, medicinal uses8, horticultural and ecological have been recognized for at least 1 200 years. The genre is therefore cultivated in Russia, China, France, etc.

• In the Hautes Alpes and in all the Southern Alps, number of producers manufacture local specialties based on bend (jams, pasta, syrups, juice, etc.). In the valley of Durance (Alpes-de-Haute-Provence), the productions based on argosa are among the local products in the same way as the Lavande.
• In Baie de Somme, in maritime Picardy.
