Characteristics

Plants acaulescenl or with a short (30 cm.) stem, freely suckering and forming dense groups. Leaves 15-25, densely rosulate, linear-lanceolate, acuminate from the middle upwards, about 15-30 cm long, 6-7 cm broad; upper surface rather flat, sub-canaliculate towards apex, fleshy, dark green often becoming purplish in the young state, powdery-glaucous all over (especially below), striate and marked with large oblong whitish spots arranged more or less in a series of irregular transverse bands; lower surface convex, very powdery-glaucous (sometimes more distinctly marked than the upper surface): margins sinuate-dentate, armed with stout horny deltoid brown-tipped teeth 6-7 mm long, 10-16 mm, distant. Inflorescence about 1-1.6 met. high, the peduncle copiously branched above the middle, the branches erectly spreading and terminating in lax racemes 30-40 cm, long. Bracts 10-12 mm long, linear-lanceolate, cuspidate, 3-5-nerved. Pedicels about 6-7 mm long. (It appears that bracts are almost twice the length of the pedicels.) Perianth 30-35 mm long, dull red, much inflated around the ovary, thence conspicuously constricted and decurved, enlarging towards the throat and slightly compressed laterally; outer segments free for about 10 mm, acute, many nerved; inner segments more obtuse, broader. Filaments included. (No mention of anthers, which, it seems, are not, or very slightly exserted.) Seeds about 7 mm long, broadly winged, dark coloured, punctate. Leaf sap yellowish. flowering period is mostly from February to April, with some forms in June-July.
More
Plants stemless or short-stemmed, 150-300 mm tall excluding inflorescence, suckering freely to form large, dense groups. Leaves 15-25 per rosette, narrowly ensiform, 200-600 x 35-80 mm, slightly channelled, upper surface with many whitish spots, usually in irregular transverse bands, lower surface with few to many spots. Inflorescence with 6-many ultimate branches, 1.0-1.7 m tall; racemes cylindric, elongate, lax, terminal; bracts deltoid-cirrhous, ±5-12 x 2 mm, 3-many-nerved. Flowers very pale to deep pink, dull or glossy, 20-30 mm long, mouth straight; outer segments free for 5-7 mm, inner segments adnate to outer; pedicels 6-11 mm long, lengthening to ±15 mm in fruit. Anthers exserted up to 3 mm. Ovary ±8 x 2-3 mm, green; style exserted up to 3 mm. Fruit 21-38 x 13-18 mm, greyish purplish brown. Seeds charcoal-grey, ±6.0 x 3.0 x 1.5 mm, with conspicuous brown wing. Flowering time mostly February to April, but plants flowering as early as November and as late as May have been recorded.
Succulent, perennial herb; acaulescent, rosettes sometimes solitary or usually suckering to form groups. Leaves with blade narrowly ovate, 150-350 mm long, usually with dried twisted apex; margins with stout, pungent, red-brown teeth, dull green, sometimes rich brown in dry conditions, with transverse bands of conspicuous, whitish, oblong spots on upper surface, usually obscurely or copiously spotted on lower surface. Flowers: inflorescence branched at ± middle or above, 0.75-2.00 m high, branches ascending, with narrowly cylindrical-acuminate, dense to very lax racemes; stamens and stigma exserted; perianth 25-35 mm long, dull red to pinkish red or coral-coloured with paler segment margins; Nov.-Apr.
Leaves in a compact rosette, spreading; lamina 15–35 cm long, 6–7 cm wide toward the base, lanceolate, usually dried and twisted at the apex, dull dark green, with transverse bands of conspicuous whitish oblong spots on the upper surface, and conspicuously or more usually obscurely spotted on the lower surface; margin with stout pungent red-brown teeth 4–7 mm long, 1–1.5 cm apart; sap drying purple.
This aloe sometimes occurs as solitary plants, but usually forms dense groups. Leaves are sometimes more distinctly spotted on the lower surface than the upper surface. Inflorescences are 1.0-1.6(-2.0) m high and branched from above the middle. Flowers are 30-35 mm long and dull red, with a dull whitish border on the outer perianth segments.
Perianth dull-red to pinkish-red or coral-coloured with segment margins paler to ± halfway, 25–35 mm long, c. 8 mm in diameter across the ovary, abruptly constricted just above, then widening and becoming slightly decurved, cylindric-trigonous; outer segments free for one-quarter to one-third with tips spreading slightly.
It is a small herb or shrub. It can occur singly or suckering. The leaves are in a compact ring. The leaves are 15-35 cm long by 6-7 cm wide toward the base. There are white spots on the upper surface. The flowers are erect and 1-2 m high.
Acaulescent or shortly caulescent, succulent herb, up to 300 mm tall, in clumps. Leaves spotted on both surfaces, 200-600 x 35-80 mm. Bracts cirrhous. Perianth mouth straight. Flowers pale to deep pink.
Inflorescence erect, 0.75–2 m high; peduncle 4–12-branched, with the lowermost branches often rebranched; branches sub-erect, subtended by scarious or sometimes leafy bracts 1–4 cm long.
Racemes 30–40 × 6 cm, cylindric, laxly flowered; bracts 6–15 mm long, linear-lanceolate, scarious; pedicels 6–12 mm long, elongating to 15–20 mm in fruit.
Perennial herb, solitary or suckering to form groups of plants of varying size, acaulescent.
Seeds c. 3.5 × 6.5 mm, blackish-brown with pale brown wings.
Capsule 25–30 × 14 mm, oblong-ovoid, yellowish-grey.
Stamens and stigma slightly exserted.
