Description

Isopogon scabriusculus is a shrub that typically grows to about 2 m (6 ft 7 in) high and wide, with reddish brown or greyish branchlets. The leaves are cylindrical, grooved or flat and narrow, up to 180 mm (7.1 in) long, sometimes forked with the undivided part up to 95 mm (3.7 in) long. The flowers are mostly arranged on the ends of branchlets, in sessile, spherical to oval heads up to 30 mm (1.2 in) in diameter with overlapping, egg-shaped involucral bracts at the base. The flowers are red or pink, sometimes hairy and the fruit is a hairy nut about 3.5 mm (0.14 in) long, fused with others in a spherical head up to 16 mm (0.63 in) long in diameter. [2] [3]

Taxonomy

Isopogon scabriusculus was first formally described in 1856 by Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis . [4] [5] (Meissner had previously published the name Isopogon scabriusculus in 1852 but without a description.) [6] [7]

In 1995, Donald Bruce Foreman described three subspecies of I. scabriusculus in Flora of Australia and the names are accepted at the Australian Plant Census. [3]

The specific epithet (scabriusculus) means "minutely scabrous", [17] :301pubiflorus means "softly hairy-flowered" [17] :377 and stenophyllus means "narrow-leaved". [17] :382

Distribution and habitat

Isopogon scabriusculus is widespread in the south-west of Western Australia where it grows on sandplains and ridges. Subspecies pubifloris grows in scrub, shrubland and woodland between Hyden, Southern Cross, Coolgardie, Lake King and the Frank Hann National Park. [9] [10] Subspecies scabriusculus grows in mallee, scrub and heath between Mullewa and Newdegate [12] [13] and subspecies stenophyllus grows in heath and shrubland, mainly between Wubin, Southern Cross and Newdegate. [15] [16]

Conservation status

All three subspecies of I. scabriusculus are classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [10] [13] [16]
