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.

Stem: generally caudex- or corm-like, branched or not, ± covered with dried leaves.
Leaf: in rosettes, evergreen or ± deciduous in summer (withering, falling or not), waxy or not, base wounding purple-red (yellow) or generally not.
Inflorescence: cyme; flower bracts ± subtending pedicels, < bracts; bracts alternate.
Flower: sepals 5, fused below; petals 5, fused at base, erect to spreading above; stamens 10, epipetalous; carpels 5, ± fused below.
Fruit: follicles 5, erect to spreading, many-seeded.
Seed: < 1 mm, narrowly ovoid, brown, striate.
± 46 species: sw North America; some used as groundcover or cultivated for ornamental. (W.R. Dudley, 1st head of Botany Department, Stanford University, 1849–1911) [Thiede 2003 in Eggli (ed.) Illus Handbook Succulent Plants 6 (Crassulaceae):85–103. Springer] Fr just before opening generally most reliable for orientation; insect damage may cause branching in taxa characterized as non-branching.
Unabridged note: Whether or not leaves of Dudleya cymosa subsp. costatifolia, Dudleya saxosa subsp. saxosa, Dudleya variegata wound purple-red, red, yellow, or some other color at base when removed is evidently unknown.
