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

Perennial herb from short, scaly caudex, glabrous [hairy]; dioecious or not. Leaf: cauline, sessile, alternate, entire to toothed. Inflorescence: generally hemispheric, generally dense. Flower: ± unisexual; sepals, petals 4–5[6], not circumscissile in fruit; sepals fused at base; petals ± free; stamens 2 × sepals in number, epipetalous; pistils 4–5(6), free or fused below. Fruit: erect. Seed: many, < 3 mm, ± fusiform, brown, striate.
± 40 species: generally montane to arctic; N temperate, especially Asia. (Greek: rose, for scent of roots)

R. integrifolia Raf. subsp. integrifolia WESTERN ROSEROOT
Plant (2)3–15(50) cm; caudex short, thick, fleshy, branched. Leaf: 5–30(50) mm, 2–15(20) mm wide, oblanceolate to obovate or elliptic, entire or toothed, tip acute to obtuse, generally green, ± glaucous or not. Inflorescence: ± 1–3 cm, 7–50-flowered, dense. Flower: most or all unisexual; sepals, petals 4(5); sepals 1.5–3 mm, lanceolate to ovate; petals free, 2–4 mm, dark red to deep red-purple (narrowly spoon-shaped, > sepals, ± spreading in staminate, to linear or awl-like, <= sepals, erect in pistillate); anthers light brown to red-purple. Fruit: 3–6(10) mm. Seed: 1.4–2 mm.
n=18. Cliffs, talus, alpine ridges, margins of meadows, streams; 1800–4000 m. Klamath Ranges, High Sierra Nevada, Warner Mountains, White and Inyo Mountains; western North America. [Sedum rosea (L.) Scop. subsp. integrifolium (Raf.) Hultén; Sedum roseum subsp. integrifolium, orth. var.] May–Aug [Online Interchange]
