Characteristics

Plants solitary or in small groups. Stem none or up to 15 cm, usually simple, sometimes with off-shoots at ground level forming small groups. Leaves 16-20, distichous (sometimes spirally twisted to rosulate in old specimens), narrowly long-deltoid, averaging 60-80 cm long, 5-6 cm broad at base, plicate-carinate and 'V' shaped in cross-section; upper surface green, usually without spots, sometimes with a few scattered spots near base, somewhat obscurely lineate; lower surface copiously white spotted low down; margins with a narrow white cartilaginous edge with firm white teeth 1-2 mm long, 1-2 mm distant, larger low down, gradually smaller to obsolescent upwards. Inflorescence simple, 1-3 from a leaf cluster, up to 1 m. and more high. Peduncle, flattened low down and somewhat bi-convex in cross-section, terete upwards, sterile-bracteate in upper half, the sterile bracts ovate very acuminate, basally amplexicaul, thin, sub-scarious, many-nerved. Racemes broadly conical, about 40-flowered, up to 20 cm long, 10-14 cm diam., the youngest buds obscured by their longer bracts, open flowers laxer, cernuous to pendulous, salmon-pink with green tips (near peach-red R.C.S.I.). Bracts ovate-acuminate, clasping their pedicels, the lowest about half to three-quarters the length of the pedicels, sub-scarious, many-nerved. Pedicels the lowest 40-45 mm long, longer in the fruit. Perianth 38-40 mm long, roundly trigonous, about 12 mm diam. at base, narrowing to about 9 mm diam. near throat, basally stipitate and narrowing into the pedicel; outer segments free almost to base, with 5-7 nerves confluent at apex, the apices sub-acute slightly spreading; inner segments free, a little broader than the outer and with more obtuse apices, with a slight keel pinkish in lower half, green near apex. Anthers not exserted to exserted 1-2 mm Stigma at length exserted up to 5 mm Capsule 40 mm long. Flowering December to February according to altitude and frosts.

Apparently stemless grass aloe 0.6-1.2 m tall, solitary or in small groups. Leaves 16-20, distichous, rarely spirally twisted to rosulate in old specimens, 400-800 x 25-60 mm, distinctly keeled, V-shaped in section, bright green, undersurface white-spotted near base, margins cartilaginous, dentate. Inflorescence a conical, sublax raceme; peduncle 0.4-1 m long, with sterile bracts; bracts ovate-acuminate, 13-33 x 6-8 mm, many-nerved. Flowers salmon-pink to blood-red, 25-40 mm long; all segments free; pedicels 30-60 mm long, lengthening in fruit. Anthers not or hardly exserted. Ovary ±5 x 2 mm; style exserted 3-5 mm. Fruit 33-40 x 12-13 mm, grey.
Succulent, perennial herb, grass-like; acaulescent or stem up to 0.15 m high, usually simple, sometimes suckering to form small groups. Leaves distichous, green, usually without spots adaxially and with copious white spots at base abaxially, obscurely lineate, narrowly long-deltoid, distinctly keeled, V-shaped in cross section, margins narrow, white, with firm, white teeth. Inflorescence simple, erect, up to 1 m or more high, with conical, dense racemes. Flowers salmon-pink near base, green at apex, 38-40 mm long; stamens not or only slightly exserted; stigma exserted. Flowering time Jan.-Mar.
Leaves distichous, or sometimes becoming rosulate, erect, grass-like, 60–80 cm long, linear, 1.5–2 cm wide, expanded to 5–6 cm wide at the base, tapering to the apex, deeply channelled on upper surface, keeled on lower surface, ± fleshy, mid-green, white-spotted towards the base especially on the lower, brownish surface; margin cartilaginous, with whitish teeth 0.5–2 mm long, the teeth crowded near the base, more distant above and obsolescent at the apex.
Perianth salmon-pink, green-tipped, 35–40 mm long and c. 12 mm in diameter across the ovary, cylindric-trigonous, narrowing toward the mouth, tapering into the pedicel; outer segments free almost to the base with tips slightly spreading.
A herb. The leaves are in two ranks. They are rather soft. They taper from the base to the tip. They are 1 m long and 3-5 cm wide. There are soft teeth along the edge. The flowering stalk is 1 m high. They are orange of pink.
Raceme 10–20 × 10–14 cm, conical, ± densely flowered, with overlapping bracts in bud; bracts 25–35 × 10 mm, ovate-acuminate; pedicels 3.5–5.5 cm long, elongating up to 8 cm in fruit.
Inflorescence simple, erect, 70–100 cm high or more; peduncle with large, pink-tinged, sterile bracts on the upper half, 2–7 cm apart.
