Description

Prostrate shrub with slender trailing stems to 30 cm long. Plants covered with star-shaped hairs on all parts. Leaves rounded to lance-shaped, 2-5 cm long, 15-25 mm wide, with wavy or lobed margins, upper surface green and sprinkled with star-shaped hairs, lower surface densely white-hairy. Petals about 2 mm long, pinkish. Fruit capsule 6-8 mm in diameter, covered with both star-shaped hairs and bristles.

Distribution

Endemic to NSW, mainly confined to the Dubbo-Mendooran-Gilgandra region, but also in the Pilliga and Nymagee areas. Recent collections made from the Upper Hunter region, and additional populations found in Goonoo SCA in response to the 2007 fires.

Habitat and ecology

  • Grows in sandy sites, often along roadsides.
  • Recorded in Eucalyptus dealbata and Eucalyptus sideroxylon communities, Melaleuca uncinata scrub, under mallee eucalypts with a Calytrix tetragona understorey, and in a recently burnt Ironbark and Callitris area. Also in Eucalyptus fibrosa subsp. nubila, Eucalyptus dealbata, Eucalyptus albens and Callitris glaucophylla woodlands north of Dubbo.
  • Other associated species include Acacia triptera, Callitris endlicheri, Eucalyptus melliodora, Allocasuarina diminuta, Philotheca salsolifolia, Xanthorrhoea species, Exocarpos cupressiformis, Leptospermum parvifolium and Kunzea parvifolia.
  • Fruiting period is summer to autumn. Flowers from August to December.
  • Appears to produce seed which persists for some time in the seed bank. Large numbers of seedlings have been observed germinating after fire at sites where the species was not apparent above ground before the fires. Clusters of individuals may be clonal.
  • The species is often found as a pioneer species of disturbed habitats. It has been recorded colonising disturbed areas such as roadsides, the edges of quarries and gravel stockpiles and a recently cleared easement under power lines.
  • Has been recorded in populations of 50+ individuals of various ages, 28 plants on the western side of the road and 58 plants on the sunnier eastern side. Populations may comprise a single cohort of individuals, or have a multi-aged structure where some individuals appear to be old with thickened runners.
