Isopogon attenuatus is a species of plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a shrub with oblong to spatula-shaped or linear leaves and spherical heads of yellow flowers.
Isopogon attenuatus is a shrub that typically grows to a height of 0.2–2m (7.9in– 6ft 6.7in) and has mostly glabrous, brownish branchlets. The leaves are oblong to spatula-shaped or linear, 80–240mm (3.1–9.4in) long and 10–20mm (0.39–0.79in) wide on a petiole about 50mm (2.0in) long, with a sharp point on the tip. The flowers are arranged in sessile, more or less spherical heads 40–50mm (1.6–2.0in) in diameter. The involucral bracts are egg-shaped, the flowers 10–15mm (0.39–0.59in) 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 25mm (0.98in) in diameter.[2][3]
This isopogon grows in woodland with a heathy understorey, in scattered population from near Perth to Albany and Mount Manypeaks, in the south-west of Western Australia.[2][3]
