This comprises three principal genera: namely, Adromischus, Cotyledon, and Umbilicus, and can be identified by the fact that it has the number of stamens equal to twice that of the petals.
ADROMISCHUS. There are about 20 species which are fairly common in collections, for they are. Although the are not as beautiful as the Cotyledons, the are most attractive. They are natives of Namaqualand and the Cape
Province. They should be grown in aconsisting of 3 parts loam, 3 parts -mould, 3 parts sharp sand, 1 part broken brick, and 1 part mortar rubble.
Adromischus festivus. A fascinating plant; the leaves are so coloured as to remind one of plover s eggs, grey-green with darker markings.
Adromischus Cooperi. Very similar to A. festivus, grey-green in colour, usually with darker markings. The leaves narrow towards the base, and are more thickened towards the top of the plant.
Adromischus maculatus. Has flat, grey-green leaves, spotted reddish-brown on both sides. The leaves have a short point at the top and are slightly rough at the edges. This is probably the best known species.
Adromischus mamillaris. A low-growing plant. The leaves, green flecked with brown, are semicircular in cross section, narrowed each side, about 12 inches long, I inch wide. They are grooved on the upper surface with definite margins.
COTYLEDON. The genus comprises some lovely plants, distinguished from the Crassulas by their five-sectioned bell-shaped. Included in this genus are small and large plants, branched, with fleshy leaves of a variety of shapes. They are easy to grow, but require a light . The should consist of 4 parts loam, 1 part sharp sand, with some broken bricks and old mortar rubble. They can be freely watered in summer, but only occasionally in winter. The plants are natives of S. Africa.
Cotyledon orbiculata. Cape Province. Makes a lovely plant, owing to its leaves being Aeonium species. P.
Umbilicus pendtdinus. The leaves are long-stalked circular, and green with reddish streaks. The pendent flowers are yellowish-white and grow on aabout 16 inches high. Sub-Family
