Aloe mitriformis subsp. comptonii is a subspecies of Aloe mitriformis from the genus of aloes in the subfamily of the Affodill family (Asphodeloideae). The epithet comptonii honors the British botanist Robert Harold Compton (1886-1979), who taught at the University of Cape Town and was the second director of the National Botanic Gardens of South Africa in Kirstenbosch.
description
Vegetative characteristics
Aloe mitriformi subsp. comptonii grows without a trunk or trunk-forming and usually forms dense groups. The short trunks are rarely up to 1 meter long. The approximately 20 lanceolate long, pointed leaves form rosettes . The rosettes have a diameter of up to 60 centimeters and are 40 to 50 centimeters high. The glaucous green, sometimes reddish tinged leaf blade is up to 30 centimeters long and 9 centimeters wide. The underside of the leaf is indistinctly keeled in the upper half. The keel has up to six spines that get larger towards the tip of the leaf. The light brown and white at its base teeth on the leaf margin are 2 to 3 millimeters long and 10 to 15 millimeters apart. The leaf sap is dry, deep orange.
Inflorescences and flowers
The inflorescence consists of three to five (rarely up to eight) branches and is 80 to 100 centimeters long. The dense, almost heady with a rounded tip or occasionally broadly conical grapes are up to 15 inches long and 9 to 10 inches wide. The ovate-lanceolate, tapered, pointed bracts have a length of 7 millimeters and are 3 millimeters wide. The cloudy, scarlet flowers are on 30 to 35 millimeter long flower stalks . The flowers are 35 to 40 millimeters long and briefly narrowed at their base. Above the ovary are slightly narrowed and then widened towards its mouth. Your outer tepals are (almost) not fused together. The stamens and the pen stand out from the flower up to 5 millimeters.

Systematics and distribution
Aloe mitriformi subsp. comptonii is widespread in the South African provinces of the Western Cape and Eastern Cape in flat, stony areas, on gentle slopes, quartzite ridges and rock faces.
The first description as Aloe comptonii by Gilbert Westacott Reynolds was published in 1950. Bernardus Joannes Maria Zonneveld placed the species in 2002 as a subspecies in the species Aloe mitriformis .
