Olearia subspicata
Olearia subspicata, commonly known as spiked daisy bush or shrubby daisy-bush, is a species of flowering plant in the family Asteraceae and is endemic to continental Australia. It is an erect shrub with more or less linear leaves and white and yellow, daisy-like inflorescences. Description
Olearia subspicata is an erect shrub that typically grows to a height of and has woody stems. The leaves are linear to narrowly elliptic, or narrowly egg-shaped or narrowly lance-shaped with the narrower end towards the base,  long and  wide and sessile. The edges of the leaves are rolled under, the upper surface is more or less glabrous and the lower surface, when visible, is woolly-hairy. The heads or daisy-like "flowers" are arranged singly or in panicles on the ends of branches or in leaf axils on a peduncle about  long and are  in diameter with a narrowly conical involucre at the base. Each head has up to 7, (usually 2 to 4) ray florets, the ligule  long, surrounding 3 to 10 yellow disc florets. Flowering time varies with distribution and the fruit is an achene  long, the pappus  long with 40 to 50 white to straw-coloured bristles  long. Taxonomy
This daisy was first formally described in 1845 by William Jackson Hooker who gave it the name Eurybia subspicata in Thomas Mitchell's Journal of an Expedition into the Interior of Tropical Australia. In 1867 George Bentham changed the name to Olearia subspicata in Flora Australiensis. The specific epithet (subspicata) means "almost spicate". Distribution and habitat
Spiked daisy bush grows in shrubland, mallee and mulga and is widely distributed in Western Australia, South Australia, the southern parts of the Northern Territory, western New South Wales, Queensland and the far north-west of Victoria. References
