description
Vegetative characteristics
Aloe broomii grows individually with a short, or up to 1 meter long, trunk. The leaves are in dense rosettes. The green, ovate-lanceolate leaves are 30 cm long, up to 10 cm wide at the base and taper to a point with a piercing end thorn. The leaf margins are reinforced with 1 to 2 millimeters long, reddish brown teeth that are 1 to 1.5 centimeters apart.
Inflorescences and flowers
The flowering time (in the southern hemisphere ) is around September. The simple and rarely branched inflorescences are 1 to 1.5 meters high and have cylindrical, racemose partial inflorescences . The racemose inflorescence is about 100 centimeters long and 6 to 8 centimeters in diameter and densely covered with individual flowers. The lanceolate, pointed bracts are 30 mm long and 15 mm wide, very fleshy and white to light lemon yellow in color with a brownish tip. The light lemon yellow flower is 25 millimeters long and has a rounded base. It expands above the ovary and narrows towards the mouth. It is completely hidden by the bracts. The outer tepals are free up to the base. The stamens and the pen stand 12 to 15 millimeters out of flowering.
Occurrence
Aloe broomii var. Broomii is native to Lesotho and the South African provinces of the Eastern Cape , Western Cape , North Cape and Free State . It grows there at altitudes of 1000 to 2000 meters on rocky ground between grass and bushes.
