description

Vegetative characteristics

Aloe ngongensis grows trunk-forming and branched from the base. The upright trunk reaches a length of up to 150 centimeters. The lanceolate, narrowed leaves form a loose rosette , which is persistent below the top of the trunk. The bluish green, occasionally a little purple tinged leaf blade is 30 to 60 centimeters long and 5 to 10 centimeters wide. The leaf surface is smooth. The brown-tipped teeth on the leaf margin are 3 to 4 millimeters long and 5 to 10 millimeters apart. The leaf sap is brown.

Inflorescences and flowers

The inflorescence has six to eight branches and reaches a length of up to 60 centimeters. The lower branches are occasionally branched again. The dense, almost capped grapes are about 6 inches long and 8 inches wide. The lanceolate, light brown bracts have a length of 7 to 10 millimeters and are 3 millimeters wide. The bright, shiny scarlet red flowers are yellowish at their mouth and are on 10 to 20 millimeter long peduncles . They are 25 to 30 millimeters long and narrowed briefly at their base. At the level of the ovary , the flowers have a diameter of 8 millimeters. Above this they are slightly narrowed and finally widened towards the mouth. Your outer tepals are not fused together over a length of 7 millimeters. The stamens and the stylus protrude 3 millimeters from the flower.
