Arabian highland aloe with dark green to dark brown, spreading to recurved leaves and pink to red flowers. Rosettes may be solitary or occasionally offsetting, reaching up to about 2 feet wide. Leaves have a rough surface texture and are thick and brittle, with very small marginal teeth (occasionally none). Fresh sap is yellow. Juveniles remain distichous for some time. Flowers are concentrated in late summer to early fall, but they may appear at other times of year, and plants may rebloom. Inflorescences may have 1-3 branches.

Found in western Yemen and southwestern Saudi Arabia at 5000-7700 feet. This area receives about 8 inches of rainfall. This species is found with Kleinia odora and Adenium obesum in habitat. It occurs with A. austroarabica, A. parvicoma, A. pseudorubroviolacea, A. sabaea, and A. woodii, with a range of natural hybrids. A. x abhaica is a hybrid with pseudorubroviolacea; A. x qaharensis is a hybrid with woodii.

This species was originally described as fleurentinorum but this spelling was later corrected to conform with the rules of nomenclature. It includes the former A. edentata, a toothless plant which was described in 2000. It is related to A. inermis, a larger plant with paler green leaves. Not uncommon in cultivation.
