Description

Spreading, prostrate shrub with ascending branchlets to 15 cm high. Leaves are compressed to the side, 8 - 17 mm long, without hairs or scales, glaucous (blue-grey with a white bloom) and often tinged red-purple. Flowers tubular, in clusters of 2 - 4, yellow -green when young, turning red in upper parts as they mature; tube 7 - 8 mm long, style 12 -16 mm white and straight. Flower surrounded by red-brown bracteoles (bract like structure at base of flower), 4 - 6 mm long, falling as flower ages. Flowers borne on stalks 1.5mm long at end of small branchlets. Fruit tiny, 1 seeded to 1.5 mm diameter.

Distribution

Occurs between Gosford and the Hawkesbury River around Calga, Kariong and Mt Karing. Known from approximately 15 sites, several within or near to Brisbane Waters NP and one within Popran NP. Occurs entirely within the Gosford Local Government Area of the Sydney Basin Bioregion.

Habitat and ecology

  • Occurs in sandy heath, scrub and woodlands often associated with sandstone rock platforms or near hanging swamps and friable sandstone shallow soils.
  • Associated species in scrub include: Banksia ericifolia, Acacia terminalis, A. oxycedrus, Angophora hispida, Hakea teretifolia, Bauera rubioides, and in woodland: Corymbia gummifera, C. eximia, Eucalyptus haemastoma and E. punctata.
  • Flowers winter and spring.
  • Seed is dispersed by ants.
  • Germination is from soil stored seed which requires heat to break seed dormancy. Germination is unlikely in the absence of fire.
  • Killed by fire and populations may flucuate in relation to time since the last fire.
  • Highly sensitive to too frequent and infrequent fire.
  • Recommended fire interval is 5-10 years.
  • Hybrids with D. fascicularis are readily identifiable by their erect habit.
