[3] The name "pearsonii" remembers the botanist and first director of the South African National Botanical Institute, Professor Pearson.

[4] This aloe grows a clump of rigidly erect stems, that are covered in four highly symmetrical rows of thick re-curved leaves.

In the dryer months the plants are red, while during times of rain the leaves fatten and turn blue-green.

[6] This aloe occurs in groups in sandy patches of the rocky Richtersveld mountains.

[7] However, severe population declines occurred between 2015-2020 due to an extended drought throughout its range, with declines of more than half across all subpopulations, and due to this species' very low recruitment, it is now considered Critically Endangered by the IUCN Red List.
