Diagnostic characters.

Aloe spicata is one of only two aloes indigenous to KwaZulu-Natal that have sessile campanulate flowers with dark nectar in a simple inflorescence. It differs from Aloe vryheidensis in often being acaulescent in KwaZulu-Natal or sometimes having erect to decumbent stems (not procumbent), spreading to recurved leaves (not erect) and an erect inflorescence (not oblique). Racemes of Aloe spicata are narrow (4-5 cm wide) with greenish-yellow flowers (not pinkish-brown). The ovary is uniformly green (without red lines).

Conservation status.

Least Concern ( Raimondo et al. 2009).

Distribution.

Northern KwaZulu-Natal, Mpumalanga and Limpopo in South Africa, also throughout Eswatini and in southern Mozambique, with an isolated record in Zimbabwe (Fig. 41 View Figure 41 ).
