WThe Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
WAizopsis is a genus of the succulent family Crassulaceae, found in E Asia.
WCotyledon is a genus of succulent plants in the family Crassulaceae. Mostly from Southern Africa, they also occur throughout the drier parts of Africa as far north as the Arabian peninsula.
WCotyledon orbiculata, commonly known as pig's ear or round-leafed navel-wort, is a South African succulent plant belonging to the genus Cotyledon.
WCotyledon tomentosa is a species of flowering plant in the family Crassulaceae, native to South Africa. It is a succulent evergreen shrub with large chunky ovate fuzzy green leaves. Its autonymous subspecies is known as the bear's paw because of the prominent "teeth" at the tips of its leaves. It forms large orange bell-shaped flowers in spring. In its native habitat, the Little Karoo region of South Africa, cotyledons usually grow in rocky quartz fields where they have excellent drainage provided by very porous soil.
WCotyledon undulate, also known as silver crown or silver ruffles, is a small succulent shrub up to 50 cm tall. It has unusual grey undulating leaves that give it a very sculptural shape. Cotyledon undulata is perhaps the most widely grown Cotyledon. The stems are covered with a thick, white, coating. The leaves are shaped like scallop shells, grey-white to blue-grey, with wavy edges and a powdery waxy coating over the whole leaf. The flowers are orange to yellow.
W× Cremnosedum is a hybrid genus produced from crosses involving the genera Cremnophila and Sedum. This bigeneric name was first published in 1981 with the introduction of the cultivar 'Little Gem' in an article advertising plants offered by the International Succulent Institute in the Cactus and Succulent Journal, the journal of the Cactus and Succulent Society of America. The 'Little Gem' cultivar was made by Mrs. and Mr. Robert Grim of San Jose, California and is described as producing a low mat of small rosettes. It prefers direct sunlight and produces small yellow flowers on short stalks.
WDiamorpha is a genus of plants in the family Crassulaceae. It is sometimes included within the genus Sedum. It is monotypic, including only the species Diamorpha smallii, an endemic of the southeastern United States. It becomes active in late fall and winter, blooms in late March, then dies. It has red succulent leaves that act to reflect light and hold water. Diamorpha smallii is found primarily on solution pools, shallow basins on rocky outcrops that contain seasonal pools. The plant is mainly found in Georgia, though populations have also been noted in Alabama, South Carolina, North Carolina, Tennessee, and Virginia. It is listed as an endangered species by the Tennessee Department of Environment and Conservation.
WHen and chicks is a common name for a group of small succulent plants, a term that indicates a plant that possesses enlarged parts to store water. It belongs to the flowering plant family Crassulaceae, native to southern Europe and northern Africa. The plants grow close to the ground with leaves formed around each other in a rosette, and propagating by offsets. The "hen" is the main, or mother, plant, and the "chicks" are a flock of offspring, which start as tiny buds on the main plant and soon sprout their own roots, taking up residence close to the mother plant.

Jovibarba have pale-greenish-yellow or yellow actinomorphic flowers with about six petals, while Sempervivum have generally pinkish flowers with around twice as many petals, which open more widely than jovibarba flowers. The common name hen and chicks is applied to some Jovibarba species.

WJovibarba heuffelii, common name Hen-and-chickens, as a plant species native to the Balkans and to the Carpathians in Europe but reportedly naturalized in Wisconsin and probably in other parts of North America. It grows on rocky outcrops.
WLenophyllum is a genus of flowering plants in the family Crassulaceae. The roughly seven species it contains are distributed in Texas in the United States and northeastern Mexico. Some authorities place it in the genus Sedum. Plants in this genus are distinguished from Sedum species by the presence of terminal inflorescences, erect petals, and opposite leaves. The name is derived from the Ancient Greek words ληνός (lenos), meaning "trough", and φύλλον (phyllon), meaning "leaf."
