Erect shrubs or trees 1–9 m tall. Bark lamellose-flakey. Hairs greyish, antrorsely spreading to patent. Young branchlets glabrous to densely hairy. Leaves mostly oblanceolate to linear-oblanceolate, 8–35 cm long, mostly 4–30 mm wide, flat, spreading to suberect, falcate, twisted through 90°, innocuous, usually strongly glaucous, glabrous, smooth. Inflorescence anauxotelic or auxotelic, 10–80-flowered; rachis 3–20 cm long. Flowers subtended by scale leaves and leaves; pedicels 4–15 mm long, erect to spreading, glabrous to densely hairy; tepals 10–16 mm long, acute to acuminate, glabrous to moderately hairy on outside; ventral tepal shallowly saccate. Anthers white; appendage obtuse, 2–4.6 mm long, recurved. Fig. 44D.

Occurs from the north of the Great Sandy Desert in W.A. through N.T. to Blackdown Tableland in central-eastern Qld, mostly within 300 km of the coast. Grows most commonly in Eucalyptus woodland to forest but also found in Melaleuca woodland or mixed woodland or the margins of vine thickets and occasionally in heath, in well-drained substrata, most commonly in sand derived from sandstone or granite, or on dunes, but also in lateritic soils or on stony hillsides and rarely in clay. Flowers June–Nov. Map 108.

W.A.: McLarty Hills, Great Sandy Desert, A.S.George 14726 (CANB); 12 miles [19 km] NNW of Elgie Cliffs Stn, M.Lazarides 6394 (AD, BRI, CANB, DNA, NSW, PERTH). N.T.: 47 miles [75 km] N of Oenpelli, G.Chippendale 8124 (AD, BRI, CANB, NSW, PERTH). Qld: Murrays Spring, P.K.Latz 1636 (CANB, DNA, NSW); SE slope of Ropers Peak, P.H.Weston 1548 & P.G.Richards (NSW).

This species is easily recognised by the combination of its lamellose and deeply fissured, dark grey bark and zygomorphic flowers. This species is widespread and morphologically variable but no broad geographic trends are evident.
