Othonna quinquedentata, commonly known as five-toothed baboon cabbage, is a short-lived perennial shrub that grows to 2 m from a suffrutex, branching above-ground to produce a few tall, erect and spreading stems. The base is woody on old plants. Large, ascending leaves grow lower down on the branched, sturdy stem parts. The upper stems are thin, leafless and wand-like.
The obovate, stalkless, bluish green leaves are thinly fleshy to leathery, smooth and hairless with red spots and streaks on their surfaces. Leaves vary in length between 5 cm and 15 cm and in width between 1 cm and 5 cm. Leaf margins are usually toothed near the tips, the number of teeth may well sometimes be five as the specific name has it (Bean and Johns, 2005; Manning, 2007; iSpot; JSTOR).
