description

Vegetative characteristics

Aloe aristata grows stemless, only rarely individually and usually forms dense clumps that consist of up to twelve rosettes . Its 100 to 150 lanceolate green leaves run into a long, dry, awn-like bristle. The leaf blade is 8 to 10 inches long and 1 to 1.5 inches wide. On the surface of the leaf there are scattered small white spots, which are more numerous and sometimes more or less arranged in transverse bands on the underside. On the upper side of the leaf there are several soft white spines near the leaf tip. On the underside of the leaf, the soft white spines are arranged in one or two rows near the tip of the leaf. On the leaf margins are 1 to 2 millimeters apart, 1 to 2 millimeters long, soft white teeth.

Inflorescences and flowers

The occasionally simple inflorescence usually consists of two to six branches and reaches a height of 50 centimeters. The loose, almost heady grape , consisting of 20 to 30 individual flowers, is 15 to 20 centimeters long and 12 to 15 centimeters wide. Their bracts are 11 to 12 millimeters long. The flowers are jasper- red on the top and lighter on the underside and are supported by 35 millimeter long flower stalks . They are 40 millimeters long, rounded at their base and have a diameter of 7 millimeters at the level of the ovary . Above this, the flowers are slightly narrowed to 6 millimeters and widened towards the mouth. The outer tepals are not fused together over a length of 7 millimeters. The stamens and the pen stand out 1 to 2 millimeters from the flower sleeve.
