Description
editAloidendron pillansii grows up to 15 m in height. It branches dichotomously, and superficially resembles Aloidendron dichotomum. It can be distinguished by its paler, wider, recurved leaves, and its taller, more sparsely branched growth form. The branches are made of a fiber that is soft and penetrable, which allows them to store water. Because of its habitat, the Aloidendron pillansii can shed itself of its branches and leaves if they deem detrimental to its survival.
Its round, bright yellow flowers are pendant, and hang down below the rosette (unlike those of the other tree aloes). They appear in Spring.
Distribution
editIt is found around the border between Namibia and South Africa, where its natural habitat is upper mountain slopes, in the arid winter-rainfall Richtersveld shrubland. It is severely threatened by habitat loss, illegal collecting, and livestock grazing. The species will not survive without intervention.
Cultivation
edit
It rarely appears in cultivation, as it is an extremely slow growing species, and difficult to cultivate.
It requires full sun, extremely well-drained rocky mineral soil, and very dry conditions. In habitat, it grows on rocky slopes in a desert region which receives its sparse rainfall predominantly in the winter.
