Description

Rough-hairy perennial forb with stout erect stems. Leaves 4-10 cm long, 2-3 cm wide, deeply lobed and broad-toothed, bright green, hairy. Flowerheads with purple "petals" and a yellow centre, 5-7 cm diameter, on thick hairy stems 5-14 cm long. The tubular female florets have tiny hairy petals concealed by scales, which become horny with rigid spreading points in fruit. The fruiting heads are egg-shaped and woody, seeds about 3 mm long.

Distribution

Occurs south from the Broken Hill district, at localities including Mazar Station south of Broken Hill and just east of the South Australian border. Also distributed throughout southern SA (including Koonamore Station, approx. 400 km NNE of Adelaide, from where the species gets its common name) and Western Australia.

Habitat and ecology

  • Grows in flat open areas on sandy calcareous soils. In central Australia, it grows mainly on alluvial floodplains. Commonly recorded from Mulga shrubland with chenopods in SA and WA. Soils include red sand, brown clay, texture-contrast soil on a scalded floodplain, and red loam to sandy loam with quartz.
  • Interstate habitats include stony plains, shallow creeklines over limestone, arid floodplains, and shallow depressions formerly filled with water.
  • Associated vegetation includes Acacia aneura shrubland with A. burkittii and Dissocarpus paradoxus.
  • Flowering from spring to early summer, the species is a hardy perennial forb which germinates or re-shoots from the base in autumn and makes new growth through the winter-spring period.
  • Generally not abundant but often forms dense stands in favourable habitats, making a colourful display when in flower. Plants have been recorded as uncommon, scattered and very localised in populations.
