description
Vegetative characteristics
Aloe vituensis grows trunk-forming and is sparsely branched. Its initially erect, later prostrate shoots are up to 40 centimeters long. The lanceolate, narrowed leaves are scattered along the shoots over a length of 15 to 20 centimeters. The leaf blade, which is yellow-green near its base and above it becomes bronze to brown, is up to 35 centimeters long and 4 centimeters wide. It is indistinctly fine striped. There are numerous lenticular or H-shaped, whitish spots on it. On the underside, the spots are more numerous. The leaf surface is smooth. The piercing, orange-brown teeth on the leaf margin are 3 to 4 millimeters long and 5 to 10 millimeters apart. The brown, finely striped leaf sheaths are up to 3 inches long. There is no leaf juice.
Inflorescences and flowers
The simple inflorescence reaches a length of about 50 to 60 centimeters. The rather dense, cylindrical and slightly tapering grapes are 7 to 8 inches long and 6 inches wide. The egg-shaped-pointed bracts have a length of about 7 to 9 millimeters and are 6 millimeters wide. The coral-pink, greenish-pointed flowers are on 4 to 7 millimeter long peduncles . They are 27 to 29 millimeters long and narrowed briefly at their base. At the level of the ovary , the flowers have a diameter of about 5 millimeters. They are narrowed above this and then widened to 8 to 10 millimeters towards the mouth. Your tepals are not fused together over a length of 6 to 8 millimeters. The stamens and the stylus barely protrude from the flower.
Systematics, distribution and endangerment
Aloe vituensis is common in northern Kenya and southeastern Sudan , usually in the shade of large shrubs or in the grass on rocky slopes at altitudes of 290 to 1525 meters.
The first description by John Gilbert Baker was published in 1898.
Aloe vituensis is in the endangered Red List species the IUCN as " Least Concern (LC) ", d. H. classified as not endangered in nature.
