Euphorbia jolkinii,
a perennial herb
of 30-50cm in height, inhabits rocky areas on seashores, forming
colonial clusters with well-developed rhizomes entering cracks deep.
Stems are thick, and alternate leaves are dense, 4-7cm in length, in
a long-oblong or oblanceolate shape. Also, the stems set some leaves
in a whorl on their ends and radiate branches in all directions from
leaf axils and bear ochathiums (cup-shaped inflorescences) with
yellow flowers. Bloom time: April-June.
