Description

Isopogon spathulatus is a shrub that typically grows to a height of 0.7–2 m (2 ft 4 in – 6 ft 7 in) and has hairy young branchlets. The leaves are linear to egg-shaped with the narrower end towards the base, 10–23 mm (0.39–0.91 in) long 1.5–7 mm (0.059–0.276 in) wide with a small point on the end. The flowers are arranged on the ends of branchlets in sessile, spherical heads 15–25 mm (0.59–0.98 in) in diameter with hairy, egg-shaped involucral bracts at the base. The flowers are pink, hairy, 14–20 mm (0.55–0.79 in) long and are present in most months followed by fruit that is a hairy nut, fused in a spherical head 15–20 mm (0.59–0.79 in) in diameter. [2] [3] [4]

Taxonomy

The species was first formally described in 1830 by Robert Brown in the Supplementum to his Prodromus Florae Novae Hollandiae et Insulae Van Diemen , based on material collected by William Baxter at King George's Sound. [5] [6]

In 1870, George Bentham reduced I. spathulatus to a variety of Isopogon buxifolius in Flora of Australia , [7] [8] but in 2015, Hislop and Rye reinstated I. spathulatus in the journal Nuytsia . [2] [9]

The specific epithet (spathulatus) means "spoon-shaped". [10]

Distribution and habitat

This isopogon grows in heath or shrubland in swampy or winter-wet areas between Ruabon, Collie and the Stirling Range in the south-west of Western Australia. [2]

Conservation status

Isopogon spathulatus is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [4]
