Aloe aculeata [family ALOACEAE]
Information
Plants stemless, 300-600 mm tall excluding inflorescence, solitary. Leaves ± 30, 250-600 x 50-120 mm, shallowly channelled, grass-green to glaucous, upper surface with few prickles, lower surface with many prickles, these on both surfaces scattered, dark brown, arising from white tubercles. Inflorescence of erect, cylindric, very dense racemes, 2-4-branched, ± 1 m tall; bracts ovate-acuminate, 6-10 x 4-7 mm, many-nerved. Flowers reddish orange to yellow in bud, orange to yellow at flowering, 23-40 mm long, mouth straight; outer segments con­nate for less than half their length, inner seg­ments free; pedicels 2-7 mm long. Anthers exserted 7-15 mm. Ovary 4.0-6.0 x 1.5-3.0 mm, green; style exserted 7-18 mm. Fruit ± 18-10 mm. Flowering time (May to) June to August.
Habitat
Reynolds (1966) states that the Zimbabwe form of this species may be distinguished from the South African form by having leaf prickles arising from white tubercular bases. Plants from the Northern Province (north of the Soutpans-berg) match the Zimbabwean form, both in the field and in cultivation. The presence of irregu­larly scattered prickles, not in a median line, on the leaf surfaces distinguishes this species from all others in the section. A. aculeata differs from A. petricola (no. 106) in having many-nerved, not 3-5-nerved, bracts which are shorter than in the latter species. The pedicels and flowers in A. aculeata tend to be longer than those of A. pet- ricola, though there is overlap in these characters.
