description

Vegetative characteristics

Aloe boscawenii grows trunk-forming and branches near the base. Their shoots are 1 to 2 meters long and 5 to 7 centimeters in diameter. They are erect for 8 to 12 inches. If the shoots are longer then they are creeping or are supported by the surrounding vegetation. The ovate-lanceolate leaves are scattered along the shoots to a distance of 20 to 30 centimeters. The light green leaf blade is 44 to 50 inches long and 8 inches wide. The leaf surface is smooth, the leaf sap is yellow. The brown-tipped, stinging teeth on the narrow, cartilaginous leaf margin are 2 to 3 millimeters long and 7 to 18 millimeters apart.

Inflorescences and flowers

The inflorescence consists of three to nine branches, of which the lower are occasionally further branched, and reaches a length of about 90 centimeters. The loose grapes at the bottom become denser towards the top. They are cylindrical, 10 to 12 inches long and 7 inches wide. The long, pointed bracts have a length of 7 millimeters and are 3 millimeters wide. The yellow flowers turn brownish towards their tips and stand on 18 millimeter long flower stalks . They are 30 millimeters long and narrowed at their base. At the level of the ovary , the flowers have a diameter of 9 millimeters, above which they are very slightly narrowed. Your outer tepals are not fused together over a length of 18 millimeters. The stamens and the stylus barely protrude from the flower.

Systematics, distribution and endangerment

Aloe boscawenii is common in Tanzania in bushes on sandy soils along the coast up to heights of 60 meters.

The first description by Hugh Basil Christian was published in 1942.

Aloe boscawenii is in the endangered Red List species the IUCN as " Critically Endangered (CR) ", d. H. classified critically endangered.
