S. Afr. Bot. 2: 116 (1936) . Type: South Africa , Limpopo Province , Pietersburg , on road to Chuniespoort , flowered in Johannesburg 14 March 1936 , G.W. Reynolds 1345 ( PRE , holo .!) Diagnostic characters : This aloe typically forms large dense colonies of up to 100 plants. Leaves are usually clearly spotted in transverse bands on the lower surface. Inflorescences are up to 0.66 m high and widely branched from about the middle with long, wide and divaricate branches so that the inflorescence is often wider than it is high ( Figure 2 ). Flowers are 30–33 mm long and coralred, with a 1 mm wide white border on the outer perianth segments. Distribution : It is centred around Polokwane (Pietersburg), but occurs from the Bela-Bela (Warmbad) and Mookgophong (Naboomspruit) area, northwards to Louis Trichardt, Wylies Poort and Musina, Limpopo Province, South Africa. Table 1 . Characters used to distinguish among the species in the Aloe zebrina -complex of summer flowering maculate aloes.
