Habit and morphology

They are squat to lanky shrubs and trees with a palm-like habit. Their leaves are typically grouped in umbrella-shaped arrangements at the tips of long erect branches. The leaves are carried on long petioles, and have conspicuous stipules. The leaves are very variable in shape, often palmately compound (''cf.'' subgenus ''Paniculata'' Strey) with leaflets likewise variable in shape, but also simple or palmate. Their usually dense inflorescences are often spiked, and their small flowers usually have 5 greenish petals. Their stems and underground parts are succulent, and their bark is often corky. These plants are best grown from seed. These plants can handle an occasional and mild frost, but a chill will make the leaves fall off.
