Raspweed (Rough Raspwort)
Haloragis aspera

Seed leaves are oblong. The more common ‘seedlings’ are shoots from an existing root system; these do not have seed leaves. True leaves are spear-shaped with deep, sharp teeth around the margin. Stems of young plants are often reddish.
Mature plants are erect with a woody base and few branches. Leaves are stalkless with a distinct mid-vein on the lower surface. Leaves usually alternate but sometimes opposite in lower parts.
Flowers are small, 2–3 mm long, purplish to greenish and occur in upper leaf forks or on spikes.
