Scientific name: Darwinia peduncularis
Gazetted date:
12 Mar 1999
Profile last updated:
13 Nov 2024
Description
A broadly spreading shrub to 1.5 m high. Leaves laterally compressed, spreading, 7 - 12 mm long, hairless. Flowers usually in pairs; peduncles 4 - 7 mm long, often curved downwards; bracts leaf-like or triangular and more or less membranous, 1 - 10 mm long; bracteoles oblong, 4 - 8 mm long, purplish red, falling early. Hypanthium (cup-like structure above the ovary) 9 - 12 mm long, 1.5 - 2.5 mm diam.
Distribution
Occurs as local disjunct populations in coastal NSW with a couple of isolated populations in the Blue Mountains. It has been recorded from Brooklyn, Berowra, Galston Gorge, Hornsby, Bargo River, Glen Davis, Mount Boonbourwa and Kings Tableland.
Habitat and ecology
- Usually grows on or near rocky outcrops on sandy, well drained, low nutrient soil over sandstone.
- Flowers in winter to early spring.
- Not likely to be capable of vegetative spread but may resprout after some disturbance.
- Likely to be killed by fire, based on the response of other Darwinia species.
- Pollinators are honeyeater birds.

Threats
- Given populations are small, it is threatened by isolation, fragmentation and local extinction.
- Inappropriate fire regimes.
- impacts from recreational use eg trail bikes, walking tracks.
- weed invasion.
- Potential for susceptibility to exotic pathogens - phytophthora cinammomi and myrtle rust, especially due to vulnerabilty to high levels of foot traffic and small population sizes.
- Honeybees harvest nectar from flowers without pollinating the plant; reduces reproductive success.
- Direct disturbance via trail maintenance as well as potential hydrological disturbance via trails draining onto habitat areas.
Recovery strategies
Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological
community. The Office of Environment and Heritage has identified
4 priority actions
to help recover the Darwinia peduncularis in New South Wales.
Activities to assist this species
- Implement appropriate fire regimes.
- Manage visitor use of known and potential habitat.
- Weed control.
- Protect areas of habitat from clearing and further fragmentation.
