Duvalia

The stems are clavate, cylindrical to spherical, in cross-section four-, five-or six-edged, and to about 10 inches long.

Each flower has five thin, elongated petal-like lobes, radiating in a star-shape, from a central raised disk or annulus.

The colour of most species flowers is shades of reddish brown, except for those of the rare Duvalia parviflora which are cream-coloured.

Only one species, Duvalia polita extends further east, and as far north into tropical Africa as Malawi and Zambia.

[2][3] Four species, occurring on the other side of the continent on the verges of the Red Sea, were formerly included in the genus Duvalia.

The rare Duvalia parviflora has smooth "potato-shaped" stems and tiny, cream-coloured flowers.
