On the underside of the leaf there are some soft thorns that are arranged in a center line or they are distributed irregularly in the upper third. There is a solid end mandrel at the tip of the blade . The whitish teeth on the leaf margin are 2 to 3 millimeters long and 10 millimeters apart.
Inflorescences and flowers
The simple inflorescence reaches a length of 40 centimeters. The rather dense, conical grapes are 15 inches long and 7 inches wide. The ovate-lanceolate bracts have a length of 15 millimeters. The bright vermilion flowers are on 15 millimeter long peduncles . The flowers are 38 millimeters long and trimmed at their base. At the level of the ovary , they have a diameter of 3 to 4 millimeters. Your outer tepals are not fused together. The stamens and the stylus protrude 5 millimeters from the flower.

Systematics and distribution
Aloe brevifolia is widespread in the open bushland in the Western Cape Province of South Africa.
The first description by Philip Miller was published in 1768. Aloe perfoliata var. Δ L. (1753) is a synonym .
A distinction is made between the following varieties :
- Aloe brevifolia var. Brevifolia
- Aloe brevifolia var. Depressa (Haw.) Baker
- Aloe brevifolia var. Postgenita (Schult. & Schult. F.) Baker
Aloe brevifolia var. Brevifolia is
a synonym for Aloe prolifera Haw. (1804).
Aloe brevifolia var. Depressa
The differences to Aloe brevifolia var. Brevifolia are: the approximately 60 leaves are 12 to 15 centimeters long and 6 centimeters wide. The leaf surface is smooth or with somewhat warty spots in the upper half. The peripheral teeth are 2 to 4 millimeters long. The inflorescence reaches a height of 60 centimeters. The bracts are about 15 millimeters long. The 40 millimeter long, fiery red flowers are on stems up to 20 millimeters long.
The first description as Aloe depressa by Adrian Hardy Haworth was published in 1804. John Gilbert Baker presented the species as a variety to the species Aloe brevifolia in 1880 . Synonyms are Aloe prolifera var. Ζ L. (1753) and Aloe serra DC. (1799) and Aloe brevifolia var. Serra (DC.) A.Berger (1908).
Aloe brevifolia var. Postgenita
In contrast to Aloe brevifolia var. Ballii , the leaves of this variety are 10 to 13 centimeters long and 4 centimeters wide.
The first description as Aloe postgenita by Joseph August and Julius Hermann Schultes was published in 1830. The species was also placed by John Gilbert Baker as a variety to the species Aloe brevifolia in 1880 . Aloe prolifera var. Major Salm-Dyck (1817) is synonymous .
