Description

Merimbula Star-hair, is a single or multistemmed shrub up to 1 metre tall (rarely up to 1.8 m). The stems are more or less erect and the smaller branches are woolly. The leaves are 20-40 mm long (to 60 mm in juveniles) and 1.5-2 mm wide, sometimes broadening a little near the rounded tip. The leaves are hairy or woolly underneath. Flowers are cream coloured and appear between October and December.

Distribution

The Merimbula Star-hair has a highly restricted and severely fragmented distribution in NSW. It is currently known from only three localities. One population is along the upper reaches of the Wallagaraugh River about 30 km south-west of Eden (in Yambulla and Timbillica State Forests). A small population is located near Middle Beach in Merimbula. The largest population is centred on the township of Tura Beach north of Merimbula, lying partly along one edge of Bournda National Park. Some of this population is concentrated in disturbed roadside habitat. It also occurs in adjacent and relatively undisturbed bushland but at apparently lower frequency. In Victoria, the species is known from occasional records in the catchments of the lower Wallagaraugh River and the upper lake of Mallacoota Inlet, areas which are more or less contiguous with the more southerly of the NSW populations.

Habitat and ecology

  • The southern (Yambulla/Timbillica) population occurs on shallow gravelly granitic soils in fairly dry open forests dominated by rough-barked eucalypts including Eucalyptus consideniana and E. croajingalongensis, with a rich shrub layer including some or all of Leptospermum spp., Kunzea ambigua, Dodonaea spp., Hakea spp., Pomaderris spp. and Acacia terminalis.
  • The northern (Bournda) population occurs on deep grey-white sands in rough-barked eucalypt forest (Eucalyptus sieberi and E. globoidea dominant) with Banksia serrata, Acacia longifolia and Grevillea mucronulata.
