Vegetative characteristics
Aloe fosteri grows without a trunk or trunk, usually sprouts and forms small groups. The trunks are up to eight inches long. The approximately 20 lanceolate, pointed leaves form rosettes . The leaf blade is about 40 inches long and 8 to 10 inches wide. The light cloudy green, indistinct lined upper surface of the leaf is covered with indistinct, dirty white, oval spots, which are more or less arranged in transverse bands. The underside of the leaf is usually not spotted. The piercing, slightly bent teeth on the leaf margin are 3 to 4 millimeters long and 10 to 15 millimeters apart. The dry leaf juice is a little purple in color.
Inflorescences and flowers
The inflorescence consists of about eight branches and is up to 2 meters long. The lower branches are branched again. The loose, narrow, cylindrical, pointed grapes are up to 40 centimeters long and 6 to 7 centimeters wide. The lanceolate, pointed bracts are usually only slightly longer than the flower stalks. The light, cloudy brick-red and slightly frosted flowers are on 6 to 9 millimeter long flower stalks . The flowers are 30 millimeters long and trimmed at their base. At the level of the ovary , they have a diameter of 9 millimeters. Above this they are suddenly narrowed to 3.5 millimeters and then widened towards their mouth. Your outer tepals are not fused together over a length of 8 millimeters. The stamens and the stylus barely protrude from the flower.
