Pultenaea arida is a spindly, prostrate or spreading shrub that typically grows to a height of 10–30 cm (3.9–11.8 in) with hairy stems. The leaves are flat, 4–6.5 mm (0.16–0.26 in) long and about 3 mm (0.12 in) wide and hairy with stipules 1.5–2.5 mm (0.059–0.098 in) long at the base. The flowers are yellow, red or orange with spots and blotches of yellow, red or orange. Each flower is borne on a pedicel 1–4.5 mm (0.039–0.177 in) long with hairy bracteoles 1–1.5 mm (0.039–0.059 in) long at the base. The sepals are 5–6.5 mm (0.20–0.26 in) long and hairy. The standard petal and wings are 5–6.5 mm (0.20–0.26 in) long and the keel 5–7 mm (0.20–0.28 in) long. Flowering occurs from September to December and the fruit is an oval pod.[2]
