Description

Homoranthus inopinatus is an erect shrub 0.7–1.4 m (2–5 ft) tall, 0.3–1 m (1–3 ft) wide. The leaves are a dull pale green, opposite and aromatic. [3]

Taxonomy and naming

Homoranthus inopinatus was first formally described in 2011 by Lachlan Copeland, Lyndley Craven and Jeremy Bruhl from a specimen collected on private property near Ballendean by Jenny and Glenn Holmes in 2002 and the description was published in Australian Systematic Botany . [4] The specific epithet (inopinatus) is a Latin word meaning "unexpected", [5] referring to the discovery of this species in an otherwise botanically well-known district. [2]

Conservation status

Currently known from a single population, H. inopinatus is threatened by inappropriate fire regimes, grazing and physical disturbance by feral pigs and deer. A ROTAP conservation code of 2E using Briggs and Leigh (1996). IUCN (2010) criteria considered as 'Critically Endangered'. [3]
