Description
Isopogon attenuatus is a shrub that typically grows to a height of 0.2–2 m and has mostly glabrous, brownish branchlets. The leaves are oblong to spatula-shaped or linear, 80–240 mm long and 10–20 mm wide on a petiole about 50 mm long, with a sharp point on the tip. The flowers are arranged in sessile, more or less spherical heads 40–50 mm in diameter. The involucral bracts are egg-shaped, the flowers 10–15 mm long and creamy yellow to pale yellow. Flowering occurs from September to February and the fruit is a hairy nut, fused in a more or less spherical head about 25 mm in diameter.
