Description

Crescent-leaved Homoranthus is a low, spreading shrub to about 40 cm tall. The flattened and distinctive crescent-shaped leaves are paired on the stem, with successive pairs at right angles to each other, and 4 - 10 mm long, 1 - 2 mm thick and less than 0.3 mm wide, with a spiky tip. The yellow flowers are about 5 mm long and are borne solitary (ie not grouped together) between stem and leaf with one to six flowers on each branch.

Distribution

Occurs near Tenterfield and Torrington on the New England Tablelands of NSW, including Bald Rock and Boonoo Boonoo National Parks near Tenterfield.

Habitat and ecology

  • Flowers from July to November. . The species does not spread vegetatively and is an obligate seeder.
  • Crescent-leaved Homoranthus grows in heath, shrub and woodland communities in sandy soils on granite outcrops and slopes.
  • Associated species include Callitris woodland with Micrantheum, Banksia and Isopogon species. A disjunct population of Homoranthus lunatus recorded from heath on a granite outcrop, was found associated with Leptospermum novae-angliae, Leucopogon neo-anglicus, Leucopogon biflorus, Prostanthera staurophylla, Brachyloma saxicola and Olax stricta.
  • Likely to be highly fire-sensitive and intolerant to frequent fire disturbance.
  • A small population of Homoranthus lunatus south-west of Torrington comprised about 20 healthy juvenile and adult plants. The species has also been recorded in populations as very rare (about 6 plants in population), with a scattered distribution, and locally common over about 3 hectares.
