Diagnostic characters.
Aloe maculata subsp. maculata
can be distinguished from other maculate aloes in KwaZulu-Natal (
Aloe dewetii
,
Aloe mudenensis
,
Aloe parvibracteata
,
Aloe prinslooi
,
Aloe pruinosa
,
Aloe suffulta
,
Aloe umfoloziensis
,
Aloe vanrooyenii
and
Aloe viridiana
) by its branched inflorescence (0.4-1.0 m high) with flat-topped, capitate, dense racemes (up to 10-12
x
12-16 cm) and pedicels of 35-45 mm long. Flowers are usually salmon pink to orange, sometimes yellow or red, 35-50 mm long, with a sub-globose basal swelling (up to 10 mm diameter). Leaves are spreading to slightly recurved, up to 25-30
x
8-12 cm and spotted on the upper surface, with the paler lower surface obscurely lineate and usually without spots. Marginal teeth are 3-5 mm long.
Conservation status.
Least Concern (
Raimondo et al. 2009
).
Distribution.
This subspecies is one of the most widely distributed of the spotted aloes. It occurs from the Cape Peninsula through the Western and Eastern Cape, into the eastern Free State, through KwaZulu-Natal to Mpumalanga, South Africa; also in Lesotho and Eswatini (Fig.
21
).
Notes.
One other subspecies is recognised, namely
A. maculata subsp. ficksburgensis
(Reynolds) Gideon F.Sm. & Figueiredo, which is only known from the eastern Free State, South Africa and western Lesotho.
