CRASSULACEAE STONECROP FAMILY

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.

AEONIUM
[Perennial herb] to shrub. Leaf: rosettes near stem tips, leaves alternate, generally obovate to oblanceolate, ciliate [or not]. Inflorescence: terminal; branches many, flowers on 1 side. Flower: erect, calyx, corolla not circumscissile in fruit; sepals [6]7–11[16], ± fused basally; petals = sepals in number, ± free, > sepals, cream or bright yellow; stamens 2 × sepals in number; pistils erect, ± free. Seed: many, 0.4–0.6 mm, ellipsoid, striate, brown.
31 species: Africa, Yemen, Madeira, Cape Verde, especially Canary Islands. (Latin: name given to Aeonium arboreum by Dioscorides, Greek botanist)
