Pimelea williamsonii is a bushy annual subshrub that typically grows to a height of 10–30 cm (3.9–11.8 in) and has densely hairy young stems. The leaves are more or less elliptic, 7–15 mm (0.28–0.59 in) long and 2–4 mm (0.079–0.157 in) wide on a short petiole. The flowers are bisexual, arranged on the ends of branches in elongated heads up to 65 mm (2.6 in) long. Each flower is on a hairy pedicel, the flower tube about 3 mm (0.12 in) long, the sepals about 1 mm (0.039 in) long, the flowers brownish and covered with short white and long brown hairs. Flowering occurs in most months with a peak in October and November.[2][3][4]
