Description

The Bargo Geebung is an erect, bushy shrub, the height of which varies between 60 cm and 2.5 m. It has slender branches with a light covering of brownish hairs on the new growth. The small, thin leaves have a lighter green lower surface. They are linear-lanceolate to lanceolate in shape, 0.8-2.4cm long and 1 - 2.3mm wide. Leaves are typically glabrous (sometimes hairy on new growth). Its yellow tubular flowers appear mainly in summer and are produced on pedicels 3-7mm long in the angles where leaves join the stem (leaf axils) on new growth. Its fruits are pear-shaped, green and pendulous, to 12 mm long. It is superficially similar to the species <I>P. nutans</I>.

Distribution

The Bargo Geebung is restricted to a small area south-west of Sydney on the western edge of the Woronora Plateau and the northern edge of the Southern Highlands. The historical limits are Picton and Douglas Park (northern), Yanderra (southern), Cataract River (eastern) and Thirlmere (western).

Habitat and ecology

  • The Bargo Geebung occurs in woodland or dry sclerophyll forest on sandstone and on heavier, well drained, loamy, gravelly soils of the Wianamatta Shale and .Hawkesbury Sandstone. It favours interface soil landscapes such as between the Blacktown Soil Landscape and the complex Mittagong Formation soils (Lucas Heights Soil Landscape) with the underlying sandstone (Hawkesbury Soil Landscape and Gymea Soil Landscape). Some of the vegetation the species occurs within would be recognised as the Shale/Sandstone Transition Forest, a listed community.
  • Plants are likely to be killed by fire and recruitment is solely from seed. The longevity is expected to be about 20 years.
  • Like most geebungs (Persoonia species) this species seems to benefit from the reduced competition and increased light available on disturbance margins including roadsides.
