Description

This pretty shrub grows to 2.5 m high. The dark green leaves are divided into 5 - 9 leaflets which are 4 - 8 mm long. They are covered by a scattering of short hairs on the upper surface. The branches are covered in fine yellow hairs. The deep pink flower clusters, which occur from spring through to summer, are held at the base of the leaves.

Distribution

Bolivia Hill Boronia occurs primarily in Bolivia Hill Nature Reserve south of Tenterfield. The population was estimated at 1000 mature plants in 1999, reportedly decreasing during the subsequent decade. However, new patches are being discovered with further field work, including a very distant record near Demon Nature Reserve in 2003.

Habitat and ecology

  • Reproduces primarily during spring but flowers have been observed in all seasons. Longevity has been estimated to be about 15 years.
  • Grows in dry sclerophyll forest amongst granite boulders. The species also grows in heathland on shallow soil in the cracks of granite outcrops.
  • Associated species in heath habitats include Acacia adunca, Acacia pycnostachya, Leptospermum microcarpum, Leptospermum brevipes, Notelaea linearis, Boronia anethifolia and Kunzea bracteolata. Dry sclerophyll forest vegetation comprises Eucalyptus prava, Eucalyptus andrewsii and Callitris endlicheri.
  • Recruitment cues other than fire, such as soil disturbance, have been suggested in the establishment of new cohorts.
