FIGURE 1. A. Aloe verecunda has a in Aloe hankeyi (Asphodelaceae subfam. Alooideae; Aloe sect. Leptoaloe), a new species from northern South Africa

FIGURE 1. A. Aloe verecunda has a wide but patchy natural geographical distribution range in northeastern South Africa. This photograph of a form with bright red flowers was taken in the North West province near the western limits of its range. B. A. cooperi growing in dense grassland near Melmoth in KwaZulu-Natal, South Africa. Note the distinctly conical inflorescences and sparsely arranged sterile bracts higher up on the peduncles. C. A large clump of A. hankeyi in full flower. D. Leaves of A. hankeyi are not keeled, unlike those of A. cooperi, which are distinctly keeled abaxially. E. Racemes of A. hankeyi are broadly conical to distinctly flat-topped. F. The sterile peduncular bracts of A. hankeyi (peduncle on the left) are much more densely concentrated towards the raceme than in A. cooperi (peduncle on the right) or A. verecunda. G. The large flowers of A. hankeyi are dull red for ⅔ of their length, with the upper ⅓ being greenish. H. Andrew John Hankey (1968–) on 21 August 2019. I. Type locality of A. hankeyi (red dot). Unvouchered site records in eastern Gauteng and western Mpumalanga are not reflected on the map. All photographs by Gideon F. Smith.

FIGURE 1. Aloe longibracteata usually grows in the often dense, fire-prone grass and forb layer in savanna vegetation or on rocky outcrops as solitary to sparsely (1- or 2-)branched rosettes. The rosettes mostly produce up to 4-branched inflorescences per flowering season. Photograph: Gideon F. Smith.

FIGURE 3 in Reinstatement of Aloe mutans (Asphodelaceae subfam. Alooideae), a distinctive, endemic, maculate aloe from the central Limpopo province of South Africa

FIGURE 3. Aloe mutans growing near Morotse in South Africa's Limpopo province. A. A solitary specimen. B. A two-headed specimen showing the brownish to yellowish green adaxial leaf surface. C. Solitary and multi-headed specimens, some of which are in flower while others are already in fruit. D. The leaf sap dries dark purplish. Abaxially the leaves are uniformly light green to greyish green; longitudinally indistinctly dark green-lined; and sometimes obscurely white-spotted, as here. E. Plants often grow in the shade of lowgrowing shrubs and small trees that act as nurse plants with only the inflorescences protruding above the shrub layer. F. The apicaL ⅓ to ½ of the perianth is yellow, which transitions through orange to strawberry pink basally. The basal swelling of the flowers is longitudinally more abruptly flattened than in A. davyana. All photographs by Gideon F. Smith.
