Duvalia is a plant genus in the tribe Stapeliae, milkweed subfamily Asclepiadoideae, in the family Apocynaceae (dogbane). The genus was first described in 1812, named after the French physician and botanist Henri-Auguste Duval (1777-1814).[1] It can be found on the Arabian peninsula, in tropical Africa and South Africa.[2][3]

The Duvalia species are succulent, perennial plants with low, planar growth. The shoots are clavate, cylindrical to spherical, in cross-section four-, five-or six-edged, and to about 10 inches long. They can range from green, gray to mottled reddish in color. The flower stems are long and bare. The hermaphroditic flowers measure 1-5 cm in diameter, and have five parts. The crown is yellow ocher, brown, red to dark purple. The five corolla lobes are flat or folded along the middle nerve.
