Olearia hygrophila, commonly known as swamp daisy or water daisy,[2] is a species of flowering plant in the family Asteraceae and is endemic to a restricted part of North Stradbroke Island in south-eastern Queensland. It is a shrub with slender stems, linear leaves and white and yellow, daisy-like inflorescences.
Olearia hygrophila is a shrub that typically grows to a height of up to 2 m (6 ft 7 in) and has slender stems. Its leaves are arranged alternately along the branchlets, linear to elliptic, 15–70 mm (0.59–2.76 in) long and 1.5–6 mm (0.059–0.236 in) wide, sometimes with a few teeth on the edges. The heads or "flowers" are arranged in panicles on the ends of branches and are 20–30 mm (0.79–1.18 in) in diameter, each head with white ray florets, the ligule 8–10 mm (0.31–0.39 in) long, surrounding yellow disc florets. Flowering mainly occurs from July to September, and the fruit is a glabrous achene 6–10 mm (0.24–0.39 in) long, the pappus about 5 mm (0.20 in) long.[2][3]
Taxonomy
This species was first formally described in 1836 by Augustin Pyramus de Candolle who gave it the name Eurybia hygrophila in his Prodromus Systematis Naturalis Regni Vegetabilis, from specimens collected by Allan Cunningham on North Stradbroke Island.[4][5] In 1867, George Bentham changed the name to Olearia hygrophila in Flora Australiensis.[6] The specific epithet (hygrophila) means "moisture-loving".[7]
