Olearia orientalis is a species of flowering plant in the family Asteraceae and is endemic to central eastern Queensland. It is a bushy shrub with egg-shaped leaves, the narrower end towards the base, and white and yellow daisy flowers.
Description
[edit]Olearia orientalis is a bushy shrub that typically grows to a height of 0.5–2 m (1 ft 8 in – 6 ft 7 in), its young branchlets often sticky. The leaves are alternately along the branchlets, egg-shaped with the narrower end towards the base, 18–37 mm (0.71–1.46 in) long and 9–14 mm (0.35–0.55 in) wide with two to four pairs of teeth on the edges. The heads or daisy-like "flowers" are arranged singly on the ends of branchlets and are 8–11 mm (0.31–0.43 in) wide on a peduncle 12–55 mm (0.47–2.17 in) long. Each head has 14 to 20 white ray florets, the ligules 3–6 mm (0.12–0.24 in) long, surrounding 16 to 26 yellow disc florets. Flowering occurs in most months and the achenes are flattened, 2.0–2.8 mm (0.079–0.110 in) long, the pappus with 31 to 40 bristles in two rows.[2]
Taxonomy and naming
[edit]Olearia orientalis was first formally described in 2017 by Anthony Bean and Peter Craig Jobson in the journal Austrobaileya from specimens collected in the Port Curtis district in 1994.[3] The specific epithet (orientalis) means "eastern", referring to the distribution of this species.[2]
Distribution and habitat
[edit]This olearia grows in woodland on serpentinite hills and ridges near Rockhampton in eastern Queensland.[2]
Conservation status
[edit]Olearia orietalis is listed as "endangered" under the Queensland Government Nature Conservation Act 1992.[4]
