'''''Aloe marlothii''''' Berger is a large, single-stemmed Southern African [[aloe]] of rocky places and open flat country, occasionally growing to 6m tall. Its distribution ranges from the Klip River Hills in [[Johannesburg]], through eastern [[Botswana]], northwards over the [[Soutpansberg]]to [[Zimbabwe]] and [[Malawi]] and eastwards through [[Swaziland]] and [[Mozambique]] to the coast. This species grades through intermediate forms into ''Aloe spectabilis'' [[G.W. Reynolds|Reynolds]] of [[Kwa-Zulu Natal]], and the two are now considered synonymous.

Named after [[Rudolf Marloth]], the renowned South African botanist, this species in full flower presents a magnificent spectacle, the trunk densely covered by the withered old leaves, which when green can be up to 1.5m in length and usually densely covered in short spines on the convex lower surfaces and less so on the concave upper surfaces.

The inflorescence is a much-branched panicle with up to 30 or exceptionally 50 racemes . Flower colour ranges from yellow through orange to bright red. Flowering colour is through the winter months, as is the case with most aloes. ''Aloe marlothii'' forms natural hybrids with some 30 or more species.
