description
Vegetative characteristics
Aloe imalotensis grows without a stem or with a short stem, is simple or branched and forms small groups. The prostrate shoots reach a length of up to 20 centimeters and are 3 centimeters thick. The 20 to 24 very fleshy, egg-shaped, pointed leaves form a dense rosette . The cloudy, greyish-green, red-tinged, indistinctly lined leaf blade is up to 30 centimeters long and 12 to 15 centimeters wide. The pink to reddish, cartilaginous leaf margin is 1 millimeter wide. The deltoid, or blunt, pink-colored teeth on the leaf margin are 1 to 1.5 millimeters long and 1 to 4 millimeters apart. Sometimes the peripheral teeth flow together. The leaf sap is dry yellow.
Inflorescences and flowers
The inflorescence has two to four branches and reaches a length of 50 to 60 centimeters. The rather dense, cylindrical, slightly pointed grapes are 10 to 20 centimeters long and 7 centimeters wide. The ovate-pointed bracts are 7 to 10 millimeters long and 3 to 4 millimeters wide. The coral-red flowers are on 15 to 18 millimeter long peduncles . The flowers are 30 to 34 millimeters long and briefly narrowed at their base. At the level of the ovary , they have a diameter of 6 millimeters. Above this they are very slightly narrowed and finally slightly expanded towards the mouth. Your tepals are almost not fused together. The stamens and the pen stand out 1 to 2 millimeters from the flower.
Systematics and distribution
Aloe imalotensis is widespread in Madagascar on rock, sandstone or slate clay at altitudes of 270 to 770 meters.
The first description by Gilbert Westacott Reynolds was published in 1957.

A distinction is made between the following varieties :
- Aloe imalotensis var. Imalotensis
- Aloe imalotensis var. Longeracemosa J.B. Castillon
Aloe imalotensis var. Longeracemosa
Aloe imalotensis var. Longeracemosa grows without a stem and forms small groups. The ten to twelve leaves are usually spread out and very broadly ovate-triangular. The light green to pale brownish leaf blade is 25 centimeters long and 15 centimeters wide. It is usually covered with numerous small round pale spots. The edge of the sheet is wavy. The flower clusters are quite loose. The red flowers are 25 millimeters long. The variety is only known from the type locality near the village of Mahaboboka and grows at an altitude of 350 meters. The first description by Jean-Bernard Castillon was published in 2000.
