Description
Michelago Parrot-pea is an erect shrub to 2.5 m tall. Its leaves are up to 7 mm long and very narrow; they are hairless, becoming bluish-green with age. The yellow and red pea-like flowers are borne singly in the axils of the leaves and are clustered towards the ends of the branchlets. The base (calyx) of the flower is up to 6 mm long, with lobes at the top that are shorter than the tube. The fruits are reddish-brown pods to 5.5 mm long and 4 mm wide, and white-hairy towards the tip.
This species has been confirmed as susceptible to the plant pathogen Phytophthora cinnamomi, with deaths observed in at least one population. Care should be taken to ensure nil Phytophthora transfer by not transferring soil (e.g. mud fragments on boots) into any sites containing this species.
Distribution
Michelago Parrot-pea is recorded from five areas on the NSW Southern Tablelands: near Windellama, where the species is locally abundant, near Mongarlowe, in Nadgigomar Nature Reserve near Braidwood, north-east of Michelago and at Numeralla. There is potential habitat between the known sites.
Habitat and ecology
- Occurs on exposed patches of clay or on rocky outcrops in eucalypt woodland often dominated by Scribbly Gum (Eucalyptus rossii), Snow Gum (E. pauciflora), Broad-leafed Peppermint (E.dives) and Red Stringybark (E. macrorhyncha).
- The understorey may be either grassy or shrubby.
- Grows adjacent to Natural Temperate Grassland in the Michelago area.
- Probably killed by fire and regeneration would be from seed stimulated to germinate by the cracking of the seed coat by fire or by physical abrasion.

Threats
- Clearing of habitat in rural - residential subdivisions.
- Grazing and trampling by stock causing root damage, prevention of seedling establishment and erosion.
- Pasture improvement.
- Habitat disturbance during road maintenance.
- Weeds and roadside spraying of herbicides for weed and fire control may be a threat.
- Off-road vehicle use and illegal dumping.
- Goats and possibly macropods browsing the plants.
- Populations on private land may be threatened by clearing, pasture creation and rural subdivision.
Recovery strategies
Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological
community. The Office of Environment and Heritage has identified
5 priority actions
to help recover the Michelago Parrot-pea in New South Wales.
Activities to assist this species
- Avoid changing land-use where species persists.
- Searches should be conducted in suitable habitat in proposed development areas.
- Limit grazing on sites.
- Erect signs to alert road maintenance staff to the presence of this species.
- Control threatening weeds where necessary.
- Avoid spraying weeds close to plants to ensure they are not impacted by poison.
- Mark sites and potential habitat onto maps used for planning road maintenance work.
- Mark sites and potential habitat onto maps used for planning weed spraying work.
