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

Annual, perennial herb, shrub, glabrous (hairy).
Stem: erect to decumbent, branched or not.
Leaf: opposite, 0.1–7 cm, linear to deltate or obovate, bases fused, ± sheathing; margins generally entire.
Inflorescence: terminal panicle or flowers 1 in axils of leaves, either 2 per node, axillary, or 1 per node, terminal but appearing axillary by overtopping of main axis.
Flower: erect, sepals 3–5, ± fused at base; petals 3–5, spreading or recurved, free or ± fused at base; stamens = sepals in number; pistils 3–5.
Fruit: spreading to erect.
Seed: 0.2–0.6 mm, elliptic to elliptic-oblong ( spheric, reniform), generally with longitudinal lines, sometimes ± smooth or papillate, red-brown.
x=(7)8.
± 250 species: especially Africa, annual ± worldwide. (Latin: diminutive of thick) Crassula argentea Thunb., a synonym of Crassula ovata (Mill.) Druce, a waif.

Inflorescence: flower 1 per node, terminal; pedicel 0.5–20 mm.
Flower: parts in 4s; sepals ± 0.5–1.5 mm, ovate to oblong, rounded to obtuse; petals > sepals, 1–2 mm, ovate to oblong.
