Rounded or sprawling, intricately branched, leafy to almost leafless, spinescent shrub to 3 m high, with spreading or retrorse, sparingly branched laterals, the ultimate branchlets mostly modified to leafless thorns 3–24 mm long. Branches ± flexuose, moderately to very sparsely pubescent with shortly stalked glandular hairs and very scattered, forked or sparingly branched, non-glandular hairs, soon glabrescent. Leaves at first solitary at the nodes, soon replaced by axillary clusters of 2–5, subsessile or with petiole to 3 mm long; lamina narrowly to very narrowly elliptic or obovate, with rounded or bluntly obtuse to bluntly acute apex, mostly 9–30 mm long, 1.5–5.5 mm wide, but up to 50 × 6 mm on new growth, entire, membranaceous to slightly fleshy, moderately to sparsely pubescent with glandular hairs 0.05–0.1 mm long and with scattered, forked and sparingly branched, non-glandular hairs 0.1–0.15 mm long. Flowers 3–7 in axillary, pedunculate, ± open cymes, these solitary or 2 or 3 together and the glabrous peduncles 5–10 mm long, with each flower subtended by 1 or 2 bracts; bracts 1.0–1.4 mm long; pedicels 5–12 mm long. Calyx 3–4 mm long. Corolla 15–21 mm long, creamy-white, the striations purple; tube rim with a corona formed from 2 or 3 swellings below each lobe; lobes linear, 10–15 mm long, 1.5–2.2 mm wide, patent to slightly inclined, lacking a tuft of hairs at the apex and with margins slightly recurved. Stamens: longer pair 3.5–4.2 mm long, shorter pair 2.5–3.5 mm long. Capsule narrowly oblong-ellipsoid, often apiculate, 5–17 mm long. Seeds 7–16 in all, 1.6–2 mm long.
Usually grows in small, scattered populations on consolidated calcareous dunes, in Eucalyptus (mallee) / Melaleuca / Acacia tall shrubland.
