Aloe parvicoma is a species of the genus Aloes in the subfamily of the Affodilla plants (Asphodeloideae). The specific epithet parvicoma is derived from the Latin words parvus for 'small' and coma for 'tufts of hair' and refers to the few-leaf rosettes at the top of the trunk.
description
Vegetative characteristics
Aloe parvicoma grows trunk-forming and sprouts from the base. The upright trunk reaches a length of 10 centimeters (rarely up to 30 centimeters) and is 2.5 centimeters thick. The approximately 15 narrow, triangular leaves are pushed to the top of the trunk. The green leaf blade is 35 to 46 inches long and 3.5 to 5.5 inches wide. The horny teeth on the leaf margin are 1 to 2 millimeters long and about 15 millimeters apart.
Inflorescences and flowers
The upright inflorescence is simple or has one or two branches. It reaches a length of up to 60 centimeters. The rather dense, cylindrical grapes are about 10 centimeters long. The bracts have a length of 8 to 10 millimeters and are 4 to 7 millimeters wide. The salmon-pink flowers become yellowish at the mouth and stand on 13 to 17 millimeter long flower stalks . They are 25 to 28 millimeters long and briefly narrowed at their base. At the level of the ovary , the flowers have a diameter of 6 millimeters. Above that, they are hardly narrowed towards the mouth. Your outer tepals are not fused together over a length of 7 to 10 millimeters. The stamens protrude 3 to 4 millimeters from the flower.
Systematics and distribution
Aloe parvicoma is common in Saudi Arabia in dense vegetation between acacia and adenium . The species is only known from the locality of the type.
