Description
''Euryops brownei'' is a woody herb or shrub of ½–3 m (1⅔–10 ft) high.
Stems and leaves
This plant has initially green but eventually blackish stems that show leaf-scars when the bases of the dead leaves have fallen. The light green leaves are set densely along the stem. They do not have a petiole, are linear in shape, 1–3¼ cm (0.4–1.3 in) long, 1–2½ mm (0.04–0.1 in) wide, a little bit narrowed above a wider and membraneous base, entire or with minute saw teeth, with a blunt tip, and a row of short hairs on the margins near the base, otherwise without hair.

Inflorescences and fruits
The plants are rich in flower heads, which stand in the higher leaf axils on their own stem (peduncle) of ¾–4½ cm (0.03–0.18 in) long, with few hairs or densely woolly. The
involucres are woolly at their base, and consist of thirteen to sixteen ovate or ovate-lanceolate bracts of 4½–6½ mm (0.18–0.26 in) long, fused with each other for the lower half or third, with a blunt or pointy tip, and short hairs at the tip. Each flower head consists of mostly thirteen (full range eleven to twenty one) bright yellow ray florets of 1–1½ cm (0.4–0.6 in) long and 2⅔–4 mm (0.11–0.16 in) wide on the outside and many yellow disc florets of 2¼–4 mm long. The indehiscent, one-seeded fruits (called
cypselas) are oblong in shape, 2½–4½ mm (0.10–0.18 in) long, with five to eight ribs, without or with some short hairs, and topped with a
pappus that consists of bristles of 1–2½ mm (0.04–0.1 in) long.
