description
Vegetative characteristics
Aloe chabaudii grows without a trunk or with a short trunk, sprouts and forms small to large groups. The approximately 20 ovate-lanceolate leaves form dense rosettes . The cloudy gray-green to glaucoma- green leaf blade is up to 50 centimeters long and 10 centimeters wide. The leaf surface is indistinctly lined. Occasionally a few scattered H-shaped spots are present. The light brown teeth near the base of the leaf on the narrow, grayish, horny leaf edge are 1 to 2 millimeters long and 5 to 10 millimeters apart. Towards the tip of the leaf, they become more brownish, more hooked and are further apart.
Inflorescences and flowers
The inflorescence consists of six to twelve branches and reaches a height of 60 to 80 centimeters (rarely up to 100 centimeters). The one to three lowest branches are branched again. The rather loose, cylindrical and slightly tapered grapes are 6 to 15 centimeters long and 10 centimeters wide. They consist of 30 to 40 flowers . The ovoid-pointed or deltoid pointed bracts have a length of 3 to 5 millimeters. The bright brick-red flowers, lighter at their mouth, are on crooked to almost horizontal, 20 to 25 millimeter long flower stalks that become shorter towards the top. The flowers are 35 to 40 millimeters long and briefly narrowed at their base. At the level of the ovary , they have a diameter of 7 millimeters. Above this, the flowers are narrowed to 5 millimeters and widened towards the mouth. Your outer tepals are not fused together over a length of 8 millimeters. The stamens and the pen stand 2 to 3 millimeters out from the flower.

Systematics and distribution
Aloe chabaudii is common in Tanzania , Zaire , Zambia , Zimbabwe , Malawi , Mozambique , Swaziland and South Africa. Aloe chabaudii var. Chabaudii grows there at altitudes of 380 to 1610 meters on or at the base of granite deposits. Aloe chabaudii var. Mlanjeana is common in Malawi on rocky slopes at an altitude of 1524 meters. The range of Aloe chabaudii var. Verekeri are fire- protected habitats on rocky ground in Mozambique and Zimbabwe.
The first description by Selmar Schönland was published in 1905. A distinction is made between the following varieties :
- Aloe chabaudii var. Chabaudii
- Aloe chabaudii var. Mlanjeana Christian
- Aloe chabaudii var. Verekeri Christian
Aloe chabaudii var. Mlanjeana
The differences to Aloe chabaudii var. Chabaudii are: The green leaves, which become brick-red in the upper part, are 30 to 40 centimeters long and 9 centimeters wide. The 3 millimeter long teeth on the horny leaf margin are 10 to 15 millimeters apart. The crooked inflorescence reaches a length of 40 to 50 centimeters. The coral red flowers are 30 to 32 millimeters long and are located on 18 to 20 millimeter long flower stalks. At ovary height, they have a diameter of 9 millimeters. The tepals are free for 12 mm.
The first description of the variety by Hugh Basil Christian was published in 1938.
Aloe chabaudii var. Verekeri
The differences to Aloe chabaudii var. Chabaudii are: The leaves are olive-green and the upper half becomes reddish during the dry season. The leaf margin is white, the teeth are 4 millimeters long and hooked. The grapes on the inflorescence are almost head-shaped and reach a length of about 8 centimeters. The color of the flowers includes various shades of red and yellow. They are 32 millimeters long and are located on 15 to 17 millimeter long flower stalks.
The first description of the variety was also by Hugh Basil Christian and was published in 1938.
