Aloe dinteri ("Namibian Partridge Aloe") is a species of plant in the genus Aloe. It is native to arid areas of Angola and Namibia.[1]

Description

The plants form stemless rosettes of up to 30 cm wide. Smaller suckers sometimes offshoot from the main stem. The long sharp, triangular leaves are dark brownish green with white linear spots and cartilaginous margins. Tall, very thin multi-branched inflorescences appear from January to March, with small sparse pale pink and sometimes bluish flowers.

It is named after German botanist Kurt Dinter. Taxonomically, it forms part of the Serrulatae series of three very closely related Aloe species, together with Aloe variegata and Aloe sladeniana. Recent phylogenetic studies have shown these three species to possibly constitute an entirely separate genus, with the suggested name Gonialoe.[2]

While this species looks rather similar to its two sister species, it can be distinguished from Aloe sladeniana by its longer leaves which curve downwards, and it can be distinguished from Aloe variegata by its large size, taller thinner sparser inflorescence, and the spots on its leaves being more linear, almost to the point of being stripes. The bracts of A.dinteri are 3 nerved, unlike its sister species which are 1 nerved. A.dinteri also has an unusually large root stock; its roots form a far larger percentage of its body weight than all the rest of the plant put together.[3]

Distribution

Aloe dinteri distribution, in red

Aloe dinteri is found in sparse populations across a large arid area of Namibia and around the verges of the Namib desert. It usually occurs in deep cracks in limestone or granite rock, or growing under scrub.

What little rain there is in this area, tends to fall in the summer. Towards the south, as the climate gradually gives way to a winter-rainfall climate, Aloe dinteri is replaced by Aloe sladeniana which inhabits the central intermediate zone, and finally by Aloe variegata even further south where winter-rainfall climate predominates.[4][5][6]

Cultivation

This species can be grown in cultivation, but needs dry conditions and very well-drained porous soil. It is relatively cold-hardy, due to the low nighttime temperatures of its desert habitat. [7]
