Ammobium craspedioides is a perennial herb mostly 30–60 cm (12–24 in) high with unbranched, more or less woolly, slender stems and single flowers.

The leaves are formed in a rosette, oblong to lance-shaped, 3–12 cm (1.2–4.7 in) long, 10–17 mm (0.39–0.67 in) wide, grey, upper surface with scale-like hairs, lower surface woolly, apex pointed and the petiole 10–30 mm (0.39–1.18 in) long.

Flowering occurs in summer and the fruit is an achene about 4 mm (0.16 in) long, smooth and light brown.

[2][3] Ammobium craspedioides was first formally described in 1857 by George Bentham and the description was published in Flora Australiensis.
