description

Vegetative characteristics

Aloe rupestris grows stem-forming and is usually simple. The upright trunk can reach a length of up to 8 meters and a diameter of 20 centimeters. The lanceolate, narrowed leaves form dense rosettes and are persistent in the upper third of the trunk. The cloudy to slightly glossy deep green leaf blade is up to 70 centimeters long and 7 to 10 centimeters wide. The reddish-brown, stinging teeth on the deep pink to light red edge of the leaf are 4 to 6 millimeters long and 8 to 12 millimeters apart.

Inflorescences and flowers

The inflorescence consists of six to nine branches and reaches a length of 100 to 125 centimeters. The lower branches are branched again. The very dense, cylindrical, slightly pointed grapes are 20 to 25 centimeters long and 7 centimeters wide. The bracts have a length of about 1 millimeter and are 2 millimeters wide. The lemon-yellow flowers , which turn orange-yellow to brownish-yellow towards the mouth, are attached to 1-millimeter-long pedicels . The slightly bulbous flowers are 20 millimeters long and rounded at their base. At the level of the ovary , the flowers have a diameter of 4 millimeters. Above that they are expanded to about their middle and finally narrowed to the mouth. Your outer tepals are not fused together over a length of 12 millimeters. The stamens and the pen stand 15 to 20 millimeters out of flowering.
