Isopogon robustus

Isopogon robustus is a shrub that typically grows to about 1.5 m (4 ft 11 in) high and 2 m (6 ft 7 in) wide with brownish branchlets. The leaves are cylindrical, up to 150 mm (5.9 in) long and 2.5–3.3 mm (0.098–0.130 in) wide and more or less sessile. The flowers are arranged in oval, sessile heads of about nineteen to twenty-five pink flowers, the heads about 38 mm (1.5 in) in diameter with egg-shaped involucral bracts at the base. Flowering occurs in October and the fruit is a hairy nut about 3–3.5 mm (0.12–0.14 in) long, fused in a spherical head 9–24 mm (0.35–0.94 in) in diameter.

This isopogon grows on laterite but is only known from a population of about 120 plants in the Parker Range near Southern Cross in the south-west of Western Australia.
