These distinctive plants are among those known as "living stones", because their highly succulent, usually stemless, blue-green leaves occur at ground level and can resemble small stones. They form small clumps of a few or many paired, usually cylindrical to egg-shaped leaves that are cleft in the center. Each stem bears just 2 leaves per season but may produce offsets over the years. In some species the old leaves persist and form a short column on which new leaves develop. Solitary daisy-like flowers, usually white, yellow, or purple, appear in the cleft.

DUVALIA SPECIES

06:14:00 DUVALIA

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). It can be found on the Arabian peninsula, in tropical Africa and South Africa.

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.
