Description en: Genus of about 40 species of dwarf, almost stemless, succulent perennials occurring among rocks and pebbles in semi-desert regions of Namibia and South Africa. They have thick, soft rootstocks that produce usually inversely cone-shaped "bodies", each composed of a pair of very fleshy leaves, 2-3cm (3/4-1 1/4in) across, with a fissure usually running along much of their lengths. On the upper surface of each leaf is a window-like, translucent panel of dots, lines, or patches. Solitary, occasionally 2 or 3, daisy-like flowers, usually 2-3cm (3/4-1 1/4in) across, sometimes larger, emerge from each fissure, mainly from midsummer to mid-autumn. They are followed by small, ovoid, fleshy capsules, containing tiny seeds. In areas where temperatures drop below 12°C (54°F), grow in a warm greenhouse or as houseplants; in warmer climates, grow in a desert garden.
