description
Vegetative characteristics
Aloe vallaris grows trunk-forming and branches out from the base. The trunk reaches a length of up to 50 centimeters. The ovoid, narrowed leaves form a dense rosette . The greyish or greenish blue to bluish green leaf blade is 22 to 34 centimeters long and 4 to 5 centimeters wide. There are a few small oval to round whitish spots near the base. They are more numerous on the underside of the leaf. The piercing, yellowish, orange or brown tipped teeth on the narrow, yellowish leaf edge are 2 to 2.5 millimeters long and 10 to 12 millimeters apart. The foamy leaf juice dries as an opaque, crystalline, yellow crust.
Inflorescences and flowers
The inclined or almost upright inflorescence is simple or has a branch. It reaches a length of more than 50 to 60 centimeters. The loose, cylindrical, pointed grapes are 17 to 45 centimeters long and about 4 centimeters wide. The egg-shaped-pointed bracts have a length of up to 4.5 millimeters and are 2.5 millimeters wide. The bright scarlet flowers are on 4 to 4.5 millimeter long peduncles . They are 20 to 26 millimeters long and rounded at their base. At the level of the ovary , the flowers have a diameter of about 5 millimeters. Above it, they are narrowed to 4.5 millimeters and finally widened to 5.5 millimeters towards the mouth. Your outer tepals are not fused together over a length of 4.5 to 6 millimeters. The stamens and the stylus barely protrude from the flower.
Systematics and distribution
Aloe vallaris is common in Angola on cliffs at heights of around 1230 meters.
