Steve Boyd, except as noted

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, erect, glabrous, branches 0 or near base. Leaf: early-deciduous, sessile, 0.4–0.7 cm, oblong-elliptic to ovoid (obovoid), basal opposite, free, not fused around stem, cauline alternate, entire, tip rounded to obtuse. Inflorescence: terminal, flowers 1–2+ in 0–3-branched cyme, subsessile. Flower: sepals 5; petals 5, ± fused at base, linear to narrow-ovate, pale to bright or green-yellow, midrib often ± red; stamens 5 or 10, anthers 0.2–0.4 mm, yellow or red-brown; pistils 5, oblong, bases rounded, styles 0.2–1.2 mm, erect or recurved, stigmas ± 0.1 mm diam. Fruit: ± indehiscent, utricle-like, erect to outcurved, glabrous or glandular. Seed: 1, 0.7–2 mm, club-like, brown.
3 species: California. (Latin: diminutive of Sedum) [Moran 1997 Haseltonia 5:53–60] Parvisedum is a superfluous name for Sedella.
