Scientific name: Persoonia acerosa
Profile last updated:
07 Sep 2012
The Needle Geebung is a small, erect to spreading shrub 1 - 2 m tall. Its bright green, pine-like foliage is very distinctive. The small, needle-like leaves are channelled on the upper surface. Flower clusters are produced along leafy shoots, not at the branch tips, as in related species. The yellow tubular flowers are up to 1 cm long and most frequently appear in summer. Fruits are pear-shaped, yellowish-green with brownish-red markings, to 14 mm long and 10 mm in diameter.
The Needle Geebung has been recorded only on the central coast and in the Blue Mountains, from Mt Tomah in the north to as far south as Hill Top where it is now believed to be extinct. Mainly in the Katoomba/ Wentworth Falls/ Springwood area.
Habitat and ecology
- The Needle Geebung occurs in dry sclerophyll forest, scrubby low-woodland and heath on low fertility soils.
- Plants are likely to be killed by fire and recruitment is solely from seed.
- This species seems to benefit from the reduced competition and increased light available on disturbance margins including roadsides.
Regional distribution and habitat
Click on a region below to view detailed distribution, habitat and vegetation information.
- Loss of habitat through clearing for urban and small-rural-lot development.
- Burning for hazard reduction and other unnatural ignitions have increased fire frequency and may threaten the species’ survival.
- Weed invasion on trail and road margins and on the edge of bushland.
- Many Persoonia species are killed following infection by Cinnamon Fungus Phytophthora cinnamomi.
- Habitat disturbance during road maintenance.
- Lack of knowledge about the threats to this species and requried management.
- Lack of knowledge about distribution of the species.
- Localised distribution places the species at risk of extinction.
- Disturbance by recreational trail bikes, 4WDs, rubbish dumping at large population on Council Reserve in Lawson

Activities to assist this species
- Ensure that personnel planning and undertaking hazard reduction burns are able to identify the species and are aware of its habitat.
- Following burning, protect populations (where possible) from further fires until plants have reached reproductive maturity.
- Erect on-site markers to alert maintenance staff and road-users to the presence of this species.
- Control threatening weeds where necessary. Avoid spraying weeds close to Needle Geebung plants to ensure they are not impacted by poison.
- Protect known habitat areas from clearing and disturbance.
- Monitor populations for the impact of Phytophthora cinnamomi.
- Mark Needle Geebung sites and potential habitat onto maps used for planning road maintenance work.
