description
Vegetative characteristics
Aloe boylei grows trunk-forming, is simple or sprouts from the base and forms groups with up to twelve shoots. The shoots are short or reach a length of up to 20 centimeters when old and are 6 centimeters thick. The approximately ten to 14 lanceolate to sword-shaped leaves form a rosette . The dark green leaf blade is 50 to 60 inches long and 1.5 to 3 inches wide. The upper side of the leaf is occasionally lined and has a few scattered elliptical spots near the base. The underside of the leaf is covered with numerous white spots from the base to the middle. The soft white leaf margin is about 2 millimeters wide. The soft, white teeth on the leaf margin are 1 to 3 millimeters long and 2 to 3 millimeters apart. They become smaller towards the tip of the leaf and are more crowded together.
Inflorescences and flowers
The simple inflorescence reaches a length of 40 to 60 centimeters. The heady grapes are 10 to 12 inches long and just as wide. They consist of about 40 flowers. The egg-shaped, pointed bracts have a length of about 20 to 23 millimeters. The salmon-pink, green-tipped flowers are on 40 to 45 millimeter long peduncles . The flowers are 30 to 35 millimeters long and narrowed at their base. At the level of the ovary , they have a diameter of 11 to 12 millimeters. Above that, the flowers are narrowed to 8 to 9 millimeters towards the mouth. Your tepals are not fused together. The stamens and the style protrude up to 1 millimeter from the flower.

Systematics and distribution
Aloe boylei is common in South Africa. Aloe boylei subsp. boylei grows in the South African provinces of KwaZulu-Natal , Mpumalanga and Limpopo on rocky, open grassy slopes at altitudes of 1,800 to 3,000 meters. Aloe boylei subsp. major is also common in the Eastern Cape Province . The subspecies grows on dry, stony grasslands at altitudes of 600 to 1800 meters.
The first description by John Gilbert Baker was published in 1892. Synonyms are Aloe micracantha Pole-Evans (1923, nom. Illeg. ICBN -Article 53.1) and Aloe agrophila Reynolds (1936).
The following subspecies are distinguished:
- Aloe boylei subsp. boylei
- Aloe boylei subsp. major Hilliard & BLBurtt
Aloe boylei subsp. major
Aloe boylei subsp. major differs from Aloe boylei subsp. boylei through a more robust habit. The leaves are 7 centimeters wide, the flowers are 40 millimeters long. The first description of this subspecies by Olive Mary Hilliard and Brian Laurence Burtt was published in 1985.
