description
Vegetative characteristics
Aloe speciosa grows trunk-forming, is simple or branched. The trunk reaches a length of up to 4 meters (rarely up to 6 meters) and is covered with perennial dead leaves. The lanceolate, narrowed leaves form a dense rosette . The cloudy, glaucous- green, bluish to reddish tinged leaf blade is 60 to 80 centimeters long and 7 to 9 centimeters wide. The light red teeth on the very narrow, deep pink to light reddish leaf margin are 1 millimeter long and about 10 millimeters apart.
Inflorescences and flowers
The arching-upright, simple inflorescence reaches a length of about 50 centimeters. The very dense, cylindrical, slightly tapered grapes are about 20 centimeters long and 12 centimeters wide. The lanceolate, blunt, brownish bracts have a length of up to 20 millimeters and are 10 millimeters wide. The bulbous, white, greenish tinged flowers stand on 5 to 8 millimeter long flower stalks . They are 20 to 35 millimeters long and rounded at their base. Above the ovary , the flowers are enlarged and finally narrowed slightly towards the mouth. Your outer tepals are almost not fused together. The stamens and the pen stand out from the flower up to 16 millimeters.
Systematics and distribution
Aloe speciosa is widespread in the South African provinces of the Western Cape and Eastern Cape on rocky slopes at heights of 500 to 800 meters.
