Pimelea clavata is an erect shrub that typically grows to a height of and has stems that are hairy near the flowers. The leaves are arranged in opposite pairs, narrowly elliptic to more or less linear, long and wide on a short petiole. The flowers are white to pale yellow, densely hairy, and borne in compact, head-like groups surrounded by two involucral bracts that are similar to the leaves but smaller, each flower on a densely hairy pedicel. The floral tube is long, the sepals long. Flowering occurs from September to February.
