Information
Perennial herb, solitary or suckering to form groups of plants of varying size, acaulescent. 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. 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. 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. Stamens and stigma slightly exserted. Capsule 25–30 × 14 mm, oblong-ovoid, yellowish-grey. Seeds c. 3.5 × 6.5 mm, blackish-brown with pale brown wings.

Notes
A laxly flowered form of A. lateritia Engl. from southeast Tanzania (see Carter in F.T.E.A., Aloaceae: 17 (1994)) is probably also this species.Aloe zebrina, as accepted here, is a very variable species flowering mainly from February to May, but also June to August. Spotting on the upper leaf surface is always conspicuous, but varies in intensity on the lower surface. The racemes are mostly laxly flowered, but vary in length and flower density, in flower-colour from dull pink to coral-red, and in the length of the pedicels, bracts and perianths. This is a broad view of the species, but it is possible that an in-depth study, preferably in the field, could establish the existence of several taxa distinct from the one described originally from the coastal regions of Angola. The identification of some material from Zimbabwe as A. parvibracteata should be treated with caution before a continuous distribution of this species from Zimbabwe into southern Mozambique has been reliably demonstrated. Furthermore, the identification of some collections from Southeast Botswana as A. transvaalensis was originally based on a report in Reynolds, Aloes S. Africa: 273 (1950), and taken up by subsequent workers; and the apparently clavate perianth of what has been identified as A. grandidentata from Botswana, is not a reliable taxonomic character. All such material can be matched in specimens from other populations within the range of A. zebrina.
