Range
This species occurs on stony soil in hot, dry, thorny bushveld in Botswana, the Northern Pro­vince and Mpumalanga; also in southern Zimbabwe. Map 74. Aloe globuligemma is similar to A. guerrae and A. procera (both indigenous to Angola), A. ortholopha (indigenous to Zimbabwe) and A. mawii (indigenous to Malawi and Mozam­bique). In A. guerrae the flowers are somewhat laxer than in A. globuligemma, the inflores­cences are much taller and plants are solitary, not forming great masses. In A. procera the inflorescences are laxer and taller than in A. globuligemma, and the flowers do not change colour as they age. Plants of A. ortholopha are solitary, with very dense, unicoloured racemes in inflorescences which are only once or twice branched, and flowers on much longer pedicels than those of A. globuligemma. A. mawii is shortly (1-2 m) caulescent and has simple, very dense racemes in which the bracts are very small and obscurely veined. In A. globuligem­ma, unlike all the other members of this section, the flowers are clavate.
