Characteristics

Plants acaulescent, rarely solitary, usually in dense compact groups of up to 12 rosettes, the rosettes 10-15 cm diam. Leaves 100-150, densely multifarious, 8-10 cm long, 10-15 mm broad at base, arenate-incurved, rather narrowly lanceolate and tapering to a long dry awn, the awns densely tufted at their apices: upper surface flat, green, with several scattered small white spots, the spots sub-tuberculate lower down becoming sub-spinulescent to spinulescent near apex; lower surface convex, green, more copiously white spotted, the spots sometimes arranged in more or less transverse bands, and with several soft white spines forming one or two rows in median line near apex; margins armed with soft white cartilaginous teeth 1-2 mm long, 1-2 mm distant, shorter nearer base, longer upwards. Inflorescence occasionally simple, usually 2-6 branched from about the middle, about 50 cm high. Racemes 15-20 cm long, 12-15 cm diam., rather laxly 20-30-flowered, the flowers Jasper Red (R.C.S.) on upper outer surface, much paler underneath. Bracts lowest about one-third the length of their pedicels. Pedicels lowest up to 35 mm long, spreading sub-obliquely, redder above, paler underneath. Perianth 40 mm long, somewhat globose and 7 mm diam. at base, slightly trigonously constricted above ovary to 6 mm diam., thence slightly decurved and enlarging towards the throat; outer segments free for 7 mm, greenish brown, about 3-nerved, the apices sub-acute, slightly spreading: inner segments dorsally adnate to the outer for their greater length, the free portion broader than the outer; with a keel; the apices more obtuse and more spreading. Filaments slightly flattened, pale rose, the 3 inner narrower and lengthening in advance of the 3 outer. Anthers exserted up to 1 mm Stigma at length exserted 1-2 mm. Ovary 8 mm long, 2-5 mm diam., olive green.
More
Plants stemless, ±100 mm tall excluding inflorescence, usually in dense clusters. Leaves 254-381 cm a rosette, lanceolate, arcuate-incurved, 50-110 x 10-17 mm, greyish green to blue-green, with white subtuberculate to subspinescent spots on both surfaces, those on lower surface sometimes forming transverse bands, lower surface with soft prickles in median rows, margins with soft white teeth, apices apiculate. Inflorescence 300-500 mm high, usually 2-6-branched; peduncles without sterile bracts; floral bracts narrowly deltoid-acuminate, ±12 x 3 mm, obscurely ±5-nerved. Flowers brownish orange above, much paler below, 30-40 mm long, arcuate-nutant at anthesis, slightly constricted above ovary; outer segments connate for most of their length, inner segments adnate to outer; pedicels 21-35 mm long. Anthers not or hardly exserted. Ovary 6.0-8.0 x 1.0-2.5 mm, olive-green; style exserted 1-2 mm. Fruit 25-30 x 8-10 mm, grey to greenish brown. Seeds grey, ±6.0 x 3.0 x 1.5 mm, narrowly winged.
Succulent, perennial herb; acaulescent, usually suckering to form dense clumps, rosettes 100-150 mm in diameter. Leaves with blade green with several scattered small, white, subtuberculate to spinulescent spots, very narrowly ovate, 80-100 mm long, apex tapering to hair-like awn; margins with soft, white, cartilaginous teeth, soft white spines in 1 or 2 rows at apex of keel. Flowers: inflorescence occasionally simple, usually branched from middle, erect, ± 0.5 m high, with lax racemes; stamens and stigma slightly exserted; perianth ± 40 mm long, red on upper surface, paler below; Nov.
