Description

Olearia eremaea is a shrub that typically grows to a height of up to 1.5 m (4 ft 11 in). Its stems and leaves are covered with minute glandular hairs. It has scattered, usually elliptic leaves arranged alternately along the branchlets, 6–16 mm (0.24–0.63 in) long and 2–5 mm (0.079–0.197 in) wide with toothed edges. Both surfaces of the leaves are sticky and densely covered with glandular hairs. The heads or daisy-like "flowers" are arranged singly on the ends of branchlets and are 15–40 mm (0.59–1.57 in) in diameter on a peduncle 18 mm (0.71 in) long. Each head has 13 to 22 white ray florets, the ligule 8.2–15.3 mm (0.32–0.60 in) long, surrounding 41 to 46 yellow disc florets. Flowering occurs in July and August and the fruit is a pale brown achene, the pappus with 16 to 25 long bristles and a smaller number of much shorter ones. [2] [3]

Taxonomy

Olearia eremaea was first formally described in 1990 by Nicholas Sèan Lander in the journal Nuytsia from specimens collected by Alex George near Cosmo Newbery in 1961. [4] The specific epithet refers to the distribution of this species in the Eremaean Botanical Province of Western Australia. [2]

Distribution and habitat

Olearia eremaea grows in shrubland on stony soil in scattered places in the Gascoyne and Great Victoria Desert biogeographic regions of inland Western Australia. [2] [3]

Conservation status

This daisy bush is listed as "not threatened" by the Department of Biodiversity, Conservation and Attractions. [3]
