Description

Petrophile globifera is a shrub that typically grows to a height of 0.7–1.2 m (2 ft 4 in–3 ft 11 in) and has hairy, yellow-grey to reddish-brown young branchlets. The leaves are more or less cylindrical, 3–6 mm (0.12–0.24 in) long, about 0.8 mm (0.031 in) wide with a pointed tip. The flowers are arranged on the ends of branchlets in sessile, elliptic to spherical heads 10–18 mm (0.39–0.71 in) in diameter, with narrow egg-shaped, sticky involucral bracts at the base. The flowers are 10–15 mm (0.39–0.59 in) long, cream-coloured to pale yellow and hairy. Flowering occurs from August to October and the fruit is a nut, fused with others in an elliptic or spherical head 9–12 mm (0.35–0.47 in) long and 10–14 mm (0.39–0.55 in) wide. [2] [3]

Taxonomy

Petrophile globifera was first formally described in 2011 by Barbara Lynette Rye and Kelly Anne Shepherd in the journal Nuytsia from material collected by Donald Bruce Foreman in 1984. [2] [4] The specific epithet (globifera) means "sphere-bearing", referring to the flower heads. [2] [5]

Distribution and habitat

This petrophile mainly grows in sand in the area between Morawa, and Pithara. [2]

Conservation status

Petrophile globifera is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife [3] meaning that it is poorly known and known from only a few locations but is not under imminent threat. [6]
