Vegetative characteristics

Aloe gerstneri grows without a stem or with a short stem and is usually simple. The 20 to 30 lanceolate, sword-shaped leaves form dense rosettes . The cloudy gray-green leaf blade is up to 60 centimeters long and 9 centimeters wide. The leaf surface is smooth. On the underside of the leaf there are occasionally a few spines near the tip along the center line. The pungent, light brown teeth on the leaf margin have a white base, are 1 to 2 millimeters long and 10 to 15 millimeters apart.

Inflorescences and flowers

The inflorescence consists of one or two branches and reaches a length of up to 130 centimeters. It is easy with young plants. The cylindrical, slightly pointed grapes are up to 36 centimeters long and 6 to 7 centimeters wide. The lanceolate bracts have a length of 18 millimeters and are 5 millimeters wide. The slightly bulbous, reddish orange flowers are on 5 millimeter long peduncles . The flowers are 24 to 30 millimeters long and very short at their base. At their center, the flowers have a diameter of about 7 millimeters. They are then narrowed towards the mouth. Your outer tepals are not fused together over a length of 15 to 17 millimeters. The stamens and the pen stand 13 to 14 millimeters out of flowering.
