Most members are shrubs or herbs with fleshy leaves, 2 whorls of stamens, and distinct or only slightly united pistils. The number of pistils is equal to the number of petals. A scale-like gland that produces nectar occurs at the base of each pistil. Although the family is widely distributed in the drier parts of he world, it occurs primarily on rocks and mountains rather than in sandy soils. Members of photosynthesis known as Crassulacean Acid Metatbolism (CAM photosynthesis) This water conserving process occurs in many plants of several families that grow in dry climates. Many members of the Crassulaceae are grown as ornamentals and in rock gardens.
