Common names: Tree Spurge [En], Euphorbe arborescente [Fr], Baum-Wolfsmilch [De], Euforbia arborea [It], Ευφορβία η δενδροειδής, Γαλατσίδα [Gr], Ağaç sütleğen [Tu]

Description: Deciduous shrub, rounded, much-branched.
The stem are spreading, glabrous on the lower part, reddish.
The leaves are alternate, sessile elliptic to oblanceolate, entire, glabrous, acute.
The inflorescence is disposed in umbel-like cluster from axils of whorled leaves. The bracts are opposite, sessile, triangular-ovate, entire, yellowish.
The fruit is spheric, deeply lobed, glabrous.
Biology: Lizards act as true pollinators of the plant, moving large quantities of pollen within and among shrubs. They are the most abundant and temporally predictable pollinators besides carrying a greater quantity of pollen than do insects, especially when insects are scarce, in high elevations habitats or in early-flowering periods, when temperatures are usually low.
Habitat: Semi-arid places. This plant is sensitive to frost, so it only grows on protected and sunny mountainsides in hilly areas.
Distribution: Mediterranean Basin, from the Iberian Peninsula and Balearic islands to Egypt, Turkey.
