Annual to shrub [(± tree-like or climbing)], fleshy.
Leaf: generally simple, alternate or opposite, in dense to open, basal (or terminal) rosettes or basal and cauline, not in rosettes, reduced distally or not, margin often ± red.
Inflorescence: generally cyme, generally bracted.
Flower: generally bisexual; sepals generally 3–5, generally ± free; petals generally 3–5, ± free or fused; stamens >> to = sepals, epipetalous or not; pistils generally 3–5, simple, fused at base or not, ovary 1-chambered, placenta 1, parietal, ovules 1–many, style 1.
Fruit: follicles, generally 3–5.
Seed: 1–many, small.
± 33 genera, ± 1400 species: ± worldwide, especially dry temperate; many cultivated for ornamental. [Eggli (ed.) 2003 Illus Handbook Succulent Plants 6 (Crassulaceae). Springer] Water-stressed plants often ± brown or ± red. Consistent terminology regarding leaves, bracts difficult; in taxa with rosettes (e.g., Aeonium, Dudleya, some Sedum), structures in rosettes are leaves, those on peduncles are bracts, and those subtending flowers are flower bracts; in taxa where inflorescence is terminal, rosette leaves may "become" bracts as stem rapidly elongates to form inflorescence. Seed numbers given per follicle. —Scientific Editor: Thomas J. Rosatti.

Key to Crassulaceae

Perennial ( annual, biennial, subshrub), generally from rhizomes or stout, scaly caudex, generally glabrous; rosettes 0 or open to dense.
Leaf: sessile, generally alternate, generally obovate to spoon-shaped.
Inflorescence: terminal, generally raceme- to panicle-like.
Flower: sepals, petals generally 5, free to fused at base, sepals < petals, obtuse to long- tapered; petals erect to spreading; stamens 8 or 10, in 2 whorls, epipetalous or not; pistils 4–5, free or fused below.
Fruit: free or fused at base, erect or spreading.
Seed: many, elliptic, often winged at both ends.
± 450 species: temps, tropical mountains, North America, Mex, C.Am, Eur, Asia, n&e Africa, Atlantic islands, Indian Ocean islands; cultivated as ornamental, green roofs. (Latin: to assuage, from healing properties of houseleek, to which Sedum was sometimes applied) Sedum roseum moved to Rhodiola.
