description

Vegetative characteristics

Aloe trigonantha grows stemless, sprouts from the base and forms dense groups. The approximately 24 lanceolate, narrowed leaves form a dense rosette . The light green, pointed pinkish-brown leaf blade is 30 to 45 centimeters long and 5 to 10 centimeters wide. There are a few elongated whitish spots on it. There are many spots on the bluish green underside of the leaf. The pinkish brown teeth on the leaf margin are about 3 millimeters long and 10 to 20 millimeters apart.

Inflorescences and flowers

The inflorescence has about three branches branched again and reaches a length of 60 to 90 centimeters. The loose, cylindrical, pointed grapes are about 20 centimeters long and 7 centimeters wide. The deltoid narrowed to ovate pointed bracts have a length of 5 to 10 millimeters and are 3 to 5 millimeters wide. The bright scarlet to orange-red, very thick and fleshy flowers are up to 15 millimeter long peduncles . They are 35 millimeters long and narrowed briefly at their base. At the level of the ovary , the flowers have a diameter of 10 to 12 millimeters. Above it, they are narrowed to 7 to 8 millimeters and finally narrowed to 3 to 4 millimeters towards the mouth. Your outer tepals are not fused together over a length of about 10 millimeters. The stamens and the pen stand out 1 to 2 millimeters from the flower.

Systematics and distribution

Aloe trigonantha is common in the northeast of Ethiopia in grasslands at altitudes of 2100 to 2500 meters. The species is only known from a small area.

The first description by Leslie Charles Leach was published in 1971.

Hazards and protective measures

Due to its wide distribution, the IUCN classifies this species as Least Concern (low risk).
