Based on genetic research, in 2013 Ronell Klopper and Gideon Smith created the genus Aloidendron to accommodate 6 species of tree aloes, including Aloe dichotoma.
The plants form trees with a rounded crown, with stems to 1 m in diameter at the base and usually 3-4 m tall (sometimes up to 9 m).
The bark on the trunk peels lengthwise, forming large scales with hard and razor-sharp edges. The leaves are about 30 cm long and 5 cm wide at their base.
In winter (May-August), the flowers appear; they are pollinated by starlings, sunbirds, weaver birds and white-eyes.
From the Brandberg Massif in Namibia to Upington, Kenhardt and the Nieuwoudtville area in South Africa, the species forms a conspicuous component 0f the landscape. The plants occur in open sites, usually in rocky terrain but also in flats.
Depending on the area, rainfall (between 50 and 300 mm per year) may occur in either summer or winter.
