Euryops is a genus of 97 species in the sunflower family, Asteraceae. They are native mostly to rocky sites in southern Africa, with a few species in other parts of Africa and on the Arabian Peninsula. They produce daisy-like flower heads from fern-like foliage.

Euryops tenuissimus are South African endemic shrubs that are perennial, up to 2.5 m high, well-branched, with the lower parts bare and upper parts of branches densely leafy. Leaves are 15-150 mm long, erect or spreading when young, reflexed when old, needle-like and sometimes divided in the upper part. Individual flower heads are borne on wiry stalks, 20-150 mm long and are clustered in the upper part of the flowering branches. Heads are 10-12 mm in diameter. The 8-24 ray florets are pale or bright yellow or orange-yellow. Disc florets are yellow, 25-150. Seeds are very small (1-3 mm long), covered in dense, short white or brown hairs and become slimy when wet.
