Preopercle without antrorse
spines on horizontal limb; horizontal limb with one to a few serrae or with irregular border; vertical limb with numerous small serrae; region of angle with larger serrae, or with roughened border.
Leaves numerous per rosette, 5dm long, narrowly triangular, densely covered with scales beneath, becoming glabrous above, margin serrate with slender antrorse
red spines, to 7mm long and slightly curved; sheaths 6cm wide, 3cm tall, lustrous castaneous beneath.
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.
Teeth in about 5 rows; 7 teeth along middle, about 17 along posterior margin, but at least one tooth missing; teeth compressed, along margins and anteriorly slender, unicuspid; mediad and caudad slightly coarser and longer, bicuspid, with strong posterior, antrorse
cusp, and minor anterior blunt or pointed cusp subdistally.
1 mm wide at base, the basal ones 3-10 mm apart, antrorse
(upper ones) to retrorse (basal ones) uncinate; fascicles 7 to 11 in number, polystichously arranged, suberect, sessile, globose-capitate, strobilate, densely rosulate, 12-15 mm long (excluding the petals), 14-17 mm in diameter, 7 to 12-flowered; floral bracts broadly triangular-ovate, acuminate, slightly carinate toward the apex, equaling to slightly shorter than the sepals, but recurved and distinctly exposing them, green, nerved, inconspicuously and sparsely white-lepidote but soon glabrous, 10-13 x 8-10 mm, subdensely spinulose, spines irregularly curved, 0.
