Classification:

Family : Liliaceae
Tribe :
Genus : Ruscus
Species : Ruscus aculeatus

Phylogenetic classification: Perennial Plants of the order Asparagales, belonging to the family and gender Ruscaceae Ruscus.

Ecology: The habitat type is forest undergrowth herbaceous médioeuropéens, basophils (limestone preferential). Range is the Atlantic-Mediterranean area, which can rerach relatively high latitude, since the plant is commonly encountered in the British Isles.

General Description: It is a rhizomatous shrub, highly branched, with secondary branches into alternate position, transformed on cladodes oval ended by a thorn, small greenish to purple flowers, presenting six tepal (three external and alternately on the inside, three small). The flowers are very discrete (small size, 5 millimeters in diameter, mounted at the bottom, just visible, the cladodes must be turned up to discover the inflorescences). The fruits are red berries.

Feature: The great peculiarity of this plant is the transformation of stems bearing flowers in flattened bodies, color green, the cladodes: photography shows an inflorescence to six tepal carried by a green body terminated by a sharp spine: it ' is not a leaf, but a short shoot, flowering (and fruiting), bearing an inflorescence racemes. The shoot cost is added to the leaf axils of a classic, scaly, very small, worn by a typical shoot caulinaire (visible on the right of the photograph).
Biology: The type inflorescences are racemic (directly supported by the cauline branches), with a gender balance polyoïque, type trioïque (existence of individual males, females and hermaphrodites), pollination type entomogame; flowering occurs September to April. It produces red berries, reminiscent in many ways holly. The release is after digestion by ruminants (release type endozoochore).

Use: It is used locally at the feast of Palm Sunday as a substitute for boxwood branches. The young shoots are edible raw or cooked like asparagus, for against, berries are considered toxic. The rhizome has circulatory virtues, because it is diuretic and vasoconstrictor hence the nickname "plant legs. The root is emollient. It contains a steroidal glycoside, the ruscogénine, used in ointments for hemorrhoids or bags under the eyes. The multiple uses of the plant is reflected in the multiplicity of its vernacular names. Known since antiquity for all these virtues, the plant was cited by Gallien.

Toxicicology: The holly has a small saponosides and potassium nitrate, is of low toxicity and appetizing properties and febrifuge. The young shoots can be eaten as asparagus. The consumption of berries is not recommended.
