Aloe richardsiae grows without a trunk and individually. The thick roots are fleshy. The eight to ten linear leaves form rosettes . They are widened at the bases and form an underground bulb 3 to 4 centimeters in diameter. The green, indistinctly lined leaf blade is 20 to 25 inches long and 1.5 inches wide. The firm, white teeth on the leaf margin are 0.5 millimeters long and 1 to 2 millimeters apart.
Inflorescences and flowers
The simple inflorescence reaches a length of 35 to 45 centimeters. The loose, cylindrical, pointed grapes are about 25 centimeters long and 5 to 6 centimeters wide. The egg-shaped, pointed bracts are 25 to 30 millimeters long and 7 to 8 millimeters wide. In the bud stage they are arranged in a brick shape. The bright orange-red flowers are on 5 to 7 millimeter long peduncles . They are up to 48 millimeters long and rounded at their base. At the level of the ovary , the flowers have a diameter of 7 to 8 millimeters. They are slightly narrowed above this and then widened towards their mouth. Your tepals are not fused together over a length of 15 millimeters. The stamens and the stylus barely protrude from the flower.
Systematics, distribution and endangerment
Aloe richardsiae is common in southwestern Tanzania on clay soil of grassy clearings in woodland at altitudes of 1075 to 1275 meters.
The first description by Gilbert Westacott Reynolds was published in 1964.
