Galium litorale is a perennial herb, from 20 to 60 cm in height.
G. litorale characteristically has a
stoloniferous habitus. It is considered a
hemicryptophyte or
chamaephyte (a subshrub). The upper stems are
pubescent, with short
internodes. The leaves are narrowly
oblanceolate in shape, 2-5 x 10–18 mm, abruptly pointed and somewhat rough in texture at their edges. The
inflorescence is erect and consists of a large, elongated panicle of many small white flowers. It has short, lateral branches. The
peduncles are 1.5–3 mm, divaricating after each flower. The flowers have a white, pubescent
corolla with a diameter of 3–4 mm and with
apiculate lobes. The fruit has a diameter of 2–3 mm, and is dark or blackish coloured when ripe. It appears to be most closely related to
Galium species from North Africa, in particular
G. poirelianum. ==Distribution==
