description

Vegetative characteristics

Aloe mitriformis subsp. distans grows trunk-forming and branches from the base. The creeping and rooting trunks are 2 to 3 meters long and 3 to 4 centimeters in diameter. Sometimes numerous branches and dense clusters are formed. The lanceolate leaves form loose rosettes and are persistent over a length of 50 centimeters. The glaucous green leaf blade is up to 15 centimeters long and 7 centimeters wide. There is a thorn at the tip of the blade . The upper side of the leaf is occasionally covered with a few scattered, whitish, almost warty spots. On the underside there are usually some almost warty, whitish spots, most of which are in the lower half. The golden-yellow teeth on the leaf margin are 3 to 4 millimeters long and 5 to 8 millimeters apart. On the underside of the leaf there are two to four similar teeth along the keel near the tip.

Inflorescences and flowers

The inflorescence consists of three to four branches and is 40 to 60 centimeters long. The dense, heady grapes are up to 8 inches long and 10 inches wide. The bracts have a length of about 8 millimeters and are 5 millimeters wide. The cloudy scarlet flowers are on 30 to 40 millimeter long peduncles . The flowers are about 40 millimeters long and rounded at their base. Above the ovary are slightly narrowed and then widened towards its mouth. Your outer tepals are not fused together. The stamens and the style protrude up to 1 millimeter from the flower.

Systematics and distribution

Aloe mitriformis subsp. distans is widespread in the South African province of Western Cape on shallow soils on Cape granite near the coast.

The first description as Aloe distans by Adrian Hardy Haworth was published in 1812. Bernardus Joannes Maria Zonneveld presented the species in 2002 as a subspecies to the species Aloe mitriformis .
