Scientific name: Pomaderris prunifolia - endangered population
Gazetted date:
29 Jan 1999
Profile last updated:
16 Dec 2022
Description
Shrub 1 - 3 metres high, stems with rusty stellate hairs. Leaves ovate to oblong to more or less elliptic, 2 - 4cm long, 8 - 15mm wide, apex broadly acute; margins more or less toothed, upper surface very wrinkled; lower surface more or less rusty with stellate hairs. Flowers yellow, on a short pedicel, in short panicles. Petals absent. Hypanthium (cup-like structure above the ovary) with long whitish hairs, capsule with long rusty hairs.
Distribution
Known from only three sites within the listed local government areas, at Rydalmere, within Rookwood Cemetery and at The Crest of Bankstown.
Habitat and ecology
- At Rydalmere it occurs along a road reserve near a creek, among grass species on sandstone.
- At Rookwood Cemetery it occurs in a small gully of degraded Cooks River / Castlereagh Ironbark Forest on shale soils.
- Does not appear to spread vegetatively. The longevity is thought to be 10-25 years.
- Buds are present for many months before flowers open.
- Probably killed by fire.
Regional distribution and habitat

Threats
- Small population size causing risk of extinction from stochastic environmental events and limited long-term viability of the species.
- Uncertain future land management practices on private land impacting the long-term viability of habitat.
- Exotic weed encroachment competing with the species and limiting recruitment.
- Lack of fire allowing ground layer vegetation to thicken limiting available light for germination and recruitment.
- Lack of knowledge of the species’ current abundance or distribution.
- Threats at the Rydalmere site include road construction or restoration, unsympathetic landscaping and landscape maintenance and pressure from residents and nearby businesses to "tidy up" the plants and their habitat.
- Threats at the Rookwood Cemetery site include clearing for burial and weed invasion.
Recovery strategies
A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.
Activities to assist this species
- Continue propagation attempts (Rookwood site).
- Education campaigns for council staff, local business and residents (Rydalmere site).
- Weed control at all sites.
- Protection of known and potential habitat at Rydalmere and Rookwood sites.
- Conduct bush regeneration and rehabilitation activities (Crest site).
- Targeted surveys should also be carried out in the area to find additional sites.
