Plants acaulescent, occasionally suckering; rosettes solitary or infrequently cespitose, 0.5–1.2 × 0.8–1 dm, rather open to somewhat dense. Leaves spreading to ascending, 40–75 (–82) × (4–) 8–10 (–11) cm; blade pale to glaucous or yellowish green to green, not cross-zoned, linearlanceolate to lanceolate, rigid, adaxially deeply guttered, abaxially convex; margins undulate to wavy, armed, teeth single, well defined, 4–10 mm, (0.8–) 1–3 (–4) cm apart, interstitial teeth (0–) 1–3 (–5), mostly along distal 2/3 of margins; apical spine reddish-brown or brown to gray, acicular, 2.5–4.5 cm. Scape 4–7 m. Inflorescences narrowly to broadly paniculate, open, not bulbiferous; bracts persistent, triangular, 1–5 cm; lateral branches (6–) 8–18, slightly ascending, comprising distal 1/4–1/3 of inflorescence, longer than 10 cm. Flowers 12–21 per cluster, erect, 3.5–6.5 (–6.7) cm; perianth golden yellow, tube not shallow, campanulate, 6–18 × (7–) 10–21 (–26) mm, limb lobes erect persistent and often leathery during and after anthesis, strongly unequal, (6–) 9–15 (–18) mm; stamens long-exserted; filaments inserted at 2 levels ca. mid perianth-tube, erect, pale-yellow, (3.2–) 3.5–5 cm; anthers yellow, 7–20 mm; ovary (1.4–) 2.2–3 (–3.3) cm, neck slightly constricted, (0.5–) 4–6 (–8) mm. Capsules sessile or short-pedicellate, narrowly oblong to obovoid, 3.5–5 cm, apex short-beaked. Seeds 6–7 mm. 2n = 60.
