Scientific name: Dodonaea sinuolata subsp. acrodentata

Conservation status in NSW: Endangered

Commonwealth status: Not listed

Profile last updated: 03 Jan 2019

Description

Shrub to 3 m high. Leaves 2-3 cm long, composed of 6-14 narrow leaflets, each 5-15.5 mm long and 1-2 mm wide, terminal leaflet shorter and lobe-like. Flowers inconspicuous. Fruit a 3-winged (rarely 4-winged) capsule, 9.5-13 mm long, 10-15 mm wide, wings 3-5.5 mm wide, leathery.

Distribution

In NSW, known from only two locations south-west plains: one near Hillston, and another north of Ivanhoe. The species is also known from central south-west Qld, in the Warrego and Maranoa districts.

Habitat and ecology

Grows on stony ridges and sandy 'jump-ups' in arid and semi-arid areas. Substrates are commonly stony red sandy-loams with limonite and quartzite pebbles.
Common associated species include open woodlands of Acacia aneura (Mulga), A. harpophylla, Eucalyptus melanophloia, E. populnea and E. cambageana (Qld).
The nominate species Dodonaea sinuolata flowers during summer and autumn (January to May) and fruit matures from July to November.
Recorded as scattered, common, locally frequent and abundant in populations.

Threats

Browsing and disturbance by feral goats.
Clearing: as a woody species with a superficial resemblance to Turpentine and Narrow-Leaf Hopbush, the plant may be mistaken for a so-called woody weed.
Limited habitat availability: the species is apparently confined to stony, limonite and quartzite ridges and 'jump-ups' in arid and semi-arid areas.
Localised extinction: susceptible to catastrophic events due to the small population size and extent.
Insufficient understanding of distribution.
Insufficient understanding of threats.
