Vegetative characteristics

Aloe nubigena grows trunk-forming, sprouts and forms dense groups. The trunks reach a length of up to 25 centimeters and are 2 centimeters thick. The linear, pointed leaves are usually arranged in two lines on the shoot, sometimes forming a rosette . The green, indistinctly lined leaf blade is up to 30 centimeters long and 1.5 centimeters wide. There are sometimes a few scattered white spots on it near the base. The underside of the leaf is spotted white, with the spots becoming more numerous towards the base of the leaf. The white teeth on the leaf margin are tiny and 1 to 2 millimeters apart. Often they are missing.

Inflorescences and flowers

The simple inflorescence reaches a length of up to 30 centimeters. The heady grapes are about 5 to 6 inches long and 5 to 6 inches wide. The egg-shaped-pointed bracts have a length of up to 14 millimeters and are 8 millimeters wide. The scarlet, slightly bulbous flowers are tipped green and stand on 10 to 25 millimeter long peduncles . They are 17 to 27 millimeters long and narrowed at their base. In the middle, the flowers have a diameter of about 6.5 millimeters. Your outer tepals are not fused together. The stamens and the stylus do not protrude from the flower.
