Isopogon villosus is a tufted shrub that typically grows to a height of and has densely hairy, reddish to dark brown branchlets. The leaves are long with 25–32 widely diverging
pinnate lobes, the lowest lobe from the base of the leaf. The flowers are arranged in
sessile, oval heads about in diameter, often clustered near the base of the plant with hairy, pointed
involucral bracts at the base but that fall as the flowers develop. The flowers are up to long, cream-coloured to yellow, and densely hairy. Flowering occurs from September to November and the fruit is a hairy
nut, fused with others in an oval head in diameter. ==Taxonomy==
