Aloe humilis is a species of aloes in the subfamily of the Affodilla family (Asphodeloideae). The specific epithet humilis comes from Latin and means 'low'.
description
Vegetative characteristics
Aloe humilis grows without a trunk, sprouts and forms dense groups. The 20 to 30 ovate-lanceolate, very sharply pointed leaves form rosettes . Their glauk- green, dew-like frosted, indistinctly lined leaf blade is about 10 centimeters long and 1.2 to 1.8 centimeters wide. There are a few warts on the top of the leaf. The underside of the leaf is more warty and covered with a few irregular, soft, white spines. The soft white teeth on the leaf edge are 2 to 3 millimeters long and 4 to 5 millimeters - or closer - apart.
Inflorescences and flowers
The simple inflorescence is 25 to 35 centimeters long. The rather loose, cylindrical grapes are up to 10 centimeters long. They consist of about 20 flowers . The lanceolate pointed bracts have a length of 25 to 35 millimeters. The scarlet, sometimes orange-red, bulbous flowers are on 25 to 35 millimeter long peduncles . The flowers are 35 to 42 millimeters long and rounded at their base. At the level of the ovary they have a diameter of 4 millimeters. Above that they are widened and narrowed towards their mouth. Your outer tepals are fused together over a length of 23 to 28 millimeters. The stamens and the style protrude up to 1 millimeter from the flower.
