White flowering Aloe ferox plants are not often seen. Here with green bud tips and green segment margins, the risk of dullness is overcome by the bright orange filaments far exserted from the open florets. The non-exserted filament bases are usually lemon yellow in colour. The anthers are brown at the stamen tips, the filaments flattened.
The leaf parts in picture have their usual dark spines in rows on margins and keels, slightly unevenly spaced. The otherwise smooth blades do show the occasional small spine, appearing out of place.
Jeppe (1969) positions the white-flowering form in the east of the species distribution, which would be the Eastern Cape, as the KwaZulu-Natal plants were still called A. candelabrum in the days when she published. The photo was, however, taken in the Little Karoo, well west of Oudtshoorn (Curtis-Scott, et al, 2020; Van Wyk and Smith, 2003 Reynolds, 1974; iNaturalist).
