Description
Isopogon crithmifolius is a shrub that typically grows to a height of 0.4–1.3 m (1 ft 4 in – 4 ft 3 in) and has hairy pale brown branchlets. The leaves are 150–400 mm (5.9–15.7 in) long on a petiole 12–25 mm (0.47–0.98 in) long, divided into two or three lobes, the lobes often further divided. The flowers are arranged in more or less spherical, sessile heads 30–35 mm (1.2–1.4 in) long in diameter with egg-shaped involucral bracts at the base. The flowers are 25–30 mm (0.98–1.18 in) long, reddish pink and glabrous. Flowering occurs from September to October and the fruit is a hairy oval nut, fused with others in a spherical cone 15–20 mm (0.59–0.79 in) in diameter.[2][3]
