Leaves are narrowly triangular, succulent, attenuate and long acuminate, green above, glaucous below, size and color may vary according with light conditions, leaf blades usually exceed 100 cm and about 5-6 cm wide at base, with serrate margins, the teeth being antrorse, 3-5 mm long, green or red tinged when exposed to strong sunlight.
Leaves 3-9; blades 4-16(-23) cm long, (0.7-)1-3.4 mm wide, flattish or channelled (at least proximally), glabrous, margins with unbranched and 2-branched prickle hairs, the unbranched ones antrorse or retrorse; inner band of leaf sheaths white-hyaline or pale brown, glabrous, the apex slightly concave; ligules 0.5-1.5 mm long, more or less rounded.
Flowers on pedicels, funnel-shaped calix, with obtuse lobes, densely sericeous outside, densely sericeous inside at base; corolla, yellow when young, later turning red, glabrous outside at base, densely sericeous with long, antrorse hairs, glabrous inside, tube 4.1-6.5 mm long, lobes 1.1-3 mm; stamens attached to corolla tube; ovary 2-locular, densely sericeous.
