||coasts of Europe, N. Africa and S.W. Asia.
||perennial plant, it can reach up to 70 centimeters.
Stem is erect, glaucous-green. Leaves are spiny, with 3 - 5 lobes. Lower
leaves are petiolated, while upper ones haven't the leaf-stalk. Flowers
are aggregated into a dense, rounded inflorescence.
||it shows some xeromorphic adaptations to survive
water-loss, including its spiny leaves and bracts to deter grazing animals
and its thick, waxy cuticle. The root system is able to grow down a meter
or more into the sand. The cuticle probably also protects the plant from
the erosive effects of blown sand.
Like some other psammophytes it is able to grow up through accreted sand,
the shoot system being stimulated into renewed growth by burial.
