Conservation status in NSW: Endangered

Commonwealth status: Not listed

Profile last updated: 18 Aug 2022

Description

Short-lived herb to 40 cm high, with thick basal leaves forming an ascending rosette and smaller stem leaves. Basal leaves 3-6 cm long, 4-12 mm wide. Flowers arranged along one side of the glandular hairy stalk. Flowers 4-6 mm long, yellow, often with purplish brown near the base, wings about 0.2 mm wide. Fruit spherical, 2.5-3 mm in diameter, seeds circular, black and glossy with a narrow white wing.

Distribution

Recorded in NSW from Tundulya Station about 40 km SE of Louth. Extends across the drier parts of southern Australia, from near the central-western coast of WA, through SA to central-western NSW.

Habitat and ecology

Grows in a variety of drier communities, mainly in mallee and Acacia scrub, and mainly in sandy soils. Recorded in NSW growing in deep red sand to sandy-loam on a stabilised sand dune and in a depression amongst sandhills.
Other habitats include gentle slopes, ridge tops, lateritic outcrops, sandy flats and pebbly to gravely sands. Associated species include Acacia aneura and Triodia scariosa.
Flowers chiefly from July to October.
The species is known to grow in disturbed areas and can become common in patches on disturbed flats.
Recorded in populations as locally common to frequent.
