description

Vegetative characteristics

Aloe pirottae grows without a stem or with a very short stem, sprouts and forms small groups. The leaves form a rosette . The dark green leaf blade is 45 to 90 inches long and 6.5 to 13 inches wide. It is covered with numerous elongated light spots. The leaf surface is smooth. The brown-tipped teeth on the leaf margin are 4 to 5.5 millimeters long and 10 to 15 millimeters apart.

Inflorescences and flowers

The inflorescence has up to 28 branches and reaches a length of 100 centimeters and more. The loose, cylindrical grapes are 7 to 33 centimeters long and often consist of single-sided flowers. The egg-shaped, pointed or tapered bracts have a length of 3 to 10 millimeters and are 2 to 5 millimeters wide. The yellow, green, orange or occasionally red, cylindrical to almost club-shaped flowers are on 3 to 9 millimeter long pedicels . They are 20 to 28 millimeters long. At the level of the ovary , the flowers are 6 to 8 millimeters in diameter. Your outer tepals are not fused together over a length of 6 to 15 millimeters. The stamens and the stylus barely protrude from the flower.

Systematics and distribution

Aloe pirottae is widespread in the south of Ethiopia and in the northeast of Kenya in open acacia woodland at altitudes of 900 to 1820 meters.

The first description by Alwin Berger was published in 1905.
