Small tree, 2–6 m high, stem simple, clothed in withered leaf remains. Leaves in a compact rosette at the stem apex, spreading becoming recurved; lamina to 1 m long, up to 15 cm wide at the base, lanceolate-attenuate, deeply channelled, dull green often tinged reddish, without spots, usually with scattered reddish-brown prickles on the lower surface; margin with pungent deltoid reddish-brown teeth 4–6 mm long and 15–25 mm apart. Inflorescences 1–4, erect to 1 m tall above the leaf rosette; peduncle stout, up to c. 6-branched, the lower branches rebranched; branches spreading upwards, subtended by brown scarious deltoid bracts to c. 10 × 15 mm, with scattered sterile bracts below each raceme. Racemes erect, 15–25 × 5–7 cm, cylindric, very densely flowered; bracts 4–6 × 4 mm, rounded, scarious, buff-coloured, reflexed; pedicels c. 1 mm long. Perianth bright glossy red to reddish-orange or occasionally almost white, 20–32 mm long, c. 5 mm in diameter across the ovary, widening to c. 7 mm at the middle and narrowing slightly toward the mouth, cylindrical-ellipsoid; outer segments free for c. three-quarters, with tips recurved.
