Found on the tip of Yorke and Fleurieu Peninsulas, Kangaroo Island and in the South-east in South Australia, growing on moist sandy to gravelly soils, sometimes close to temporarily flooded areas; commonly associated with limestone, mainly in scrub of coastal heath or mallee vegetation. Also found in Victoria. Native. Uncommon in South Australia. Rare in Victoria.

Dense shrublets with flexible branches often scrambling to 1.5 m rarely up to 4 m high, covered in hairs. Leaves without axillary tuft of hairs; petiole to 1.6 mm long; leaves obovate to oblanceolate, 10.4 mm long and 7.2 mm wide; rounded to rarely obtuse with apex of central vein bulging and covered with stellate hairs; more or less abruptly tapering into petiole; usually flat, hairy above and below. Flowers pale-yellow petals being shorter than the calyx and remaining tubular (not opening widely), on peduncle to 17.3 mm long; terminal on all branches, or leaf-opposing when over-topped by growth from axillary buds, with linear bract. Flowering between August and December. Fruits are brown capsule with 2 carpels, pubescent, with erect styles from the apex. Seeds are brown ovoid seed to 2.5 mm long and 2 mm wide.
Seed collection and propagation
Collect seeds between October and January. Collect mature capsules that are turning a pale straw-colour and contain brown seeds. Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. This genus tend to have low seed viability. From one collection, the seed viability was average, at 50%. This species has morpho-physiological dormancy and can be difficult to germinate.
