Aloe hereroensis, in Afrikaans commonly the vlakte-aalwyn (plains aloe) or sandaalwyn (sand aloe), usually grows a single rosette, but may branch into clumps of up to three similar ones. The lower leaf surface is characteristically spotted, especially in young plants, whilst the upper one is clear of such spots, distinguishing the species from the maculate aloes.
