Description

Calotis lappulacea is slender, upright or straggling, multi-branched perennial or small under-storey shrub to 20–50 cm (7.9–19.7 in) high. The stems and leaves are sparsely covered with coarse, rough to flattened, straight, rigid hairs. The leaves are oblong to narrowly egg-shaped, sessile, 4–20 mm (0.16–0.79 in) long, 1–4 mm (0.039–0.157 in) wide, entire or deeply divided, mostly toothed toward the apex and basal leaves. The globular-shaped flowers are at the end of upright stems, 3–8 mm (0.12–0.31 in) in diameter, florets 40-60, yellow and 2–4 mm (0.079–0.157 in) long. Flowering occurs mostly from September to January but may flower throughout the year. The fruit is an achene, flattened, warty, spiny and about 1.5 mm (0.059 in) long.[2][3][4]
