description
Vegetative characteristics
Aloe andongensis grows trunk-forming and branched. The upright, occasionally prostrate trunks reach lengths of 30 to 60 centimeters. About 14 lanceolate, narrowed leaves form a rosette . Below that, the leaves are persistent to a length of 30 centimeters. The gray-green leaf blade is 20 to 25 inches long and 6 to 7 inches wide. The upper side of the leaf is usually not speckled. However, sometimes spots are sparse. On the underside there are numerous crowded white spots near the base. The teeth on the slightly horny leaf margin are 2 to 3 millimeters long and 5 to 7 millimeters apart.
Inflorescences and flowers
The inflorescence consists of two to three branches and reaches a height of 20 to 30 centimeters. The almost head-shaped to cylindrical-narrowed grapes are 6 to 12 centimeters long and 6 to 8 centimeters wide. The lanceolate-pointed bracts have a length of 5 to 8 millimeters and are 3 millimeters wide. The pale orange-scarlet flowers are on 14 to 18 millimeter long peduncles . The flowers are 25 millimeters long, lighter at the mouth and briefly narrowed at their base. At the level of the ovary they have a diameter of 5 to 8 millimeters, are narrowed above it to 4 to 5 millimeters and widened to 6 to 7 millimeters towards the mouth. Your outer tepals are not fused together over a length of 8 millimeters. The stamens and the stylus barely protrude from the flower.

Systematics and distribution
Aloe andongensis is common in Angola . Aloe andongensis var. Andongensis grows on exposed rocks at altitudes of 1050 to 1525 meters. Aloe andongensis var. Repens grows on the slopes of rounded granite hills.
The first description by John Gilbert Baker was published in 1878. A distinction is made between the following varieties :
- Aloe andongensis var. Andongensis
- Aloe andongensis var. Repens L.C. Leach
Aloe andongensis var. Repens
The differences to Aloe andongensis var. Andongensis are: the trunk is creeping and large, spreading clumps are formed. The leaves are smaller and narrower in proportion. They are more covered with white spots, with the spots tending to form wavy transverse bands. The marginal teeth are more crowded. The first description of this variety by Leslie Charles Leach was published in 1974.
