Scientific name: Dodonaea microzyga var. microzyga
Profile last updated:
01 Nov 2022
Description
Rigid hairless shrub, with sticky, varnished, wedge-shaped leaflets notched at the tip. Leaves composed of 3-7 leaflets, each 2-4 mm long and 1-2 mm wide. Flowers inconspicuous, solitary or paired. Fruit a dull brown to bright red capsule with 3 or 4 vertical wings, 12-15 mm long and 15-18 mm wide including the wings. Very showy when in fruit with the bright red winged capsules massed along the branches.
Distribution
Presently confined to the far north-western plains of NSW, where it is restricted to very localised occurrences at Peak Hill near Milparinka. Widely distributed in arid SA, extending into southern NT and western Qld.
Habitat and ecology
- Grows in arid open woodland or shrubland, mostly on stony rises, hills and ranges of ironstone and granite.
- Soils mostly skeletal and stony, including calcareous clay-loam, limestone soil and shaly soil.
- Associated species in central Australia include Casuarina cristata, Eucalyptus socialis, Acacia sowdenii, A. kempeana, A. tetragonophylla and Eremophila spp.
- Flowers from May to July, with mature capsules present from August to November. In western NSW flowering time is mostly in spring.
- Recorded in populations as rare, locally infrequent, moderately frequent and common.

Threats
- Feral goats (the rocky habitats are vulnerable to erosion and grazing disturbances).
- Clearing (as a woody species with a superficial resemblance to Turpentine and Narrow-Leaf Hopbush, the plant may be mistaken for a woody weed).
- Limited habitat availability (the species is confined to stony, ironstone and granite ridges in arid and semi-arid areas).
- Localised extinction (susceptible to catastrophic events due to the small population size and extent).
- Lack of information on the species in NSW to inform a conservation management strategy.
Recovery strategies
A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.
Activities to assist this species
- Protect existing populations from feral goats through appropriate controls or fencing.
- No further degradation of potential habitat.
- Instigate monitoring studies within known populations.
- No further loss of extant populations.
- Surveys required to confirm known and locate new populations.
