Scientific name: Boronia umbellata
Profile last updated:
11 Oct 2022
Description
Orara Boronia is an open shrub, 1 – 2 m tall, with upright branches. The fragrant, paired leaves are divided into one or two pairs of leaflets with a longer terminal leaflet. Dense hairs cover the underside of the leaves, branchlets and new shoots. Clusters of dark pink, four-petalled flowers, 7 - 10 mm long, are held at the base of the leaves, and are produced in spring and early summer. The fruit is smooth and has four lobes.
Distribution
Found at only a few locations between Glenreagh and Lower Bucca, north of Coffs Harbour, but it is locally common in the restricted area where it occurs.
Habitat and ecology
- This Boronia grows as an understorey shrub in and around gullies in wet open forest.
- It appears to regenerate well after disturbance, but it is not known whether prolonged or repeated disturbance affects long-term persistence.
