Characteristics

Plants acaulescent or with a stem up to 20 cm, sometimes solitary, usually in small groups. Leaves about 20, rosulate, narrowly lanceolate-attenuate, rather fleshy, about 40 cm long, 8-10 cm broad, erectly spreading and recurved in upper quarter; upper surface flat low down, slightly canaliculate towards apex, pale dull green, obscurely lineate and obscurely spotted throughout, the large dull white oval spots confluent and more or less arranged in a series of undulating interrupted transverse bands; lower surface convex, duller green, obscurely lineate, usually without spots; margins sinuate-dentate armed with deltoid pungent slightly deflexed teeth which are about 3-4 mm long, 10-15 mm distant. (The leaf sap dries purplish.) Inflorescence up to 2 met. high, usually branched above the middle, with about 8 arcuate-erect branches, the 1-3 lowest with 1-3 branchlets forming a rather compact panicle of about 12 racemes. Peduncle slightly flattened and about 3-4 cm diam. low down, coated with a greyish powdery substance. Racemes narrowly cylindric-acuminate, the terminal the highest and up to 40 cm long, 6-7 cm diam., rather laxly 40-50-flowered, the lateral shorter and fewer flowered. Pedicels the lowest of terminal racemes 6-9 mm, long. Bracts narrowly lanceolate-acuminate, sub-scarious, many-nerved, usually a little longer than their pedicels. Perianth pale dull brick-red, somewhat pruinose, 30 mm long, with a sub-globose basal swelling 9 mm diam., constricted above the ovary to 5.5 mm diam., thence decurved and enlarging towards the throat, the mouth wide open; outer segments free for 8 mm, very obscurely nerved, with a dull white 1 mm broad marginal border, and sub-acute spreading apices; inner segments broader than the outer and with broader white borders, the apices more obtuse and more spreading. Filaments pale lemon, filiform-flattened, the 3 inner narrower and lengthening in advance of the 3 outer, with their anthers in turn exserted 1-2 mm Stigma at length exserted 1-2 mm. Ovary light green, 8 mm long, 3 mm diam., finely 6-grooved, slightly tapering to the style.
More
This aloe sometimes occurs as solitary rosettes, but usually forms small groups. Leaves are very narrow, yellowish green to dull green and usually without spots on the lower surface. Peduncle and flowers are lightly covered with a grey powdery bloom. Inflorescences are up to 2 m high and compactly branched from above the middle. Flowers are ± 30 mm long and pale dull brick red, with a 1 mm wide dull white border on the outer perianth segments.
Leaves spreading-erect, rosulate; lamina 30–45 cm long, 5–10 cm wide toward the base, lanceolate-attenuate, fleshy, light green, obscurely lineate on both surfaces, with faint whitish spots on the upper surface, usually without spots on the lower surface; margin with pungent, deltoid, pale brown-tipped teeth 2–4 mm long, 10–15 mm apart; sap pale purplish.
Perianth pale brick-red, 27–30 mm long, c. 8 mm in diameter across the ovary, constricted just above then widening and becoming slightly decurved, cylindric-trigonous; outer segments free for less than one-third, with pale margins above, and with spreading tips.
Inflorescence erect, 1.2–2 m high; peduncle stout, with up to 8-branches, the lower branches rebranching; branches ascending, subtended by lanceolate, often leafy bracts to 5 cm long.
Racemes 20–40 × 7 cm, cylindric, ± laxly flowered; bracts 8–15 × 3 mm, lanceolate-acuminate; pedicels 5–8 mm long, distinctly shorter than the bracts.
Perennial herb, solitary or suckering to form small groups of plants, acaulescent or with a short thick stem to 20 cm long.
Seeds c. 3.5 × 7.5 mm, black with grey, sparsely spotted wings.
Capsule c. 33 × 14 mm, oblong-ovoid, yellowish-grey.
Stamens and stigma slightly exserted.
