Single-stemmed, usually very densely branched flat-topped shrub, 0.3–2 m tall, non-sprouting. Leaves in lower parts alternate, flat and linear, usually whorled in flowering parts, concave, narrowly obovate, extremely rigid, 2.8–12 cm long, 2.5–10 mm wide, entire, acuminate, mid-green; longitudinal veins prominent at least on underside, 1 above (sometimes obscure), 1–3 below; pinnate veins visible but obscure. Inflorescence with 12–18 flowers; pedicels 3.5–5 mm long, glabrous. Perianth pale yellowish green, split to base abaxially only. Pistil 30–35 mm long; gland obovoid. Fruit 1–3 per axil, obliquely broadly ovate in lateral view, 2–2.7 cm long, 1.3–1.8 cm wide, shortly apiculate, not or shortly beaked, not corky. Seed obliquely ovate, 12–17 mm long, 6.5–11 mm wide; wing extending down both sides of body, blackish brown, sometimes with paler streaks. 

Widespread in south-western W.A. from Mt Caroline south to Wagin and Denmark and east to Israelite Bay. Sometimes a common component of heath and scrub-heath in sandy often gravelly soil. Flowers May–Sept. Map 168.

W.A.: between Mt Bland and Middle Mt Barren, G.Keighery 497 (PERTH); Frank Hann Natl Park, Monk 298 (PERTH); near base of Mt Gibbs, c. 35 km NE of Lake King, K.Newbey 5488 (PERTH); 8 km NE of Kalgan R. along Albany–Borden road, P.Short 2281 & L.Haegi (AD, MEL, PERTH).

Considerable variation in leaf width occurs in this species, but as yet a pattern suggesting taxonomic correlation has not been recognised. Broad-leaved populations are restricted in occurrence but appear not to occur to the exclusion of narrow-leaved plants. Plants from the sand plain region north of Perth previously included under H. corymbosa have been recognised as the distinct species, H. eneabba .
