Aloe purpurea

Locally known as "Mazambron" or "Socotrine du Pays") is a species of Aloe endemic to the island of Mauritius, in the Indian Ocean, where it formerly occurred on dry rocky slopes and outcrops, the highland plateaus, and the forests of the west.

[1] This highly variable species grows an erect stem 7–10 cm in diameter, and can reach a height of 3 meters (unlike its closest relative Aloe tormentorii which is usually acaulescent or decumbent).

Its long, slender, ensiform to lanceolate leaves are more recurved and narrower than those of Aloe tormentorii, reaching a length of up to 1 meter, but a maximum of only 12 cm width at the base.

The plant seemed to have a different internal structure too, and its leaves produced large amounts of an unusual yellow gel when cut open.

However, virtually all of the viable natural habitat had been destroyed long beforehand, so it is impossible to verify if there were others like it, or if it was even a surviving remnant of a different Aloe entity.

It is beginning to be propagated as an ornamental and landscaping plant in Mauritius; a locally indigenous alternative to Aloe vera.
