Sedum praealtum
GREEN COCKSCOMB

Higher Taxonomy
Family: CrassulaceaeView DescriptionDichotomous Key

Common Name: STONECROP FAMILY
Habit: 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.
Genera In Family: +- 33 genera, +- 1400 species: +- worldwide, especially dry temperate; many cultivated for ornamental. Note: 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.

Genus: SedumView DescriptionDichotomous Key

Common Name: STONECROP
Habit: Perennial herb (annual, biennial, subshrub), generally from rhizomes or stout, scaly caudex, generally glabrous; rosettes 0 or open to dense. Leaf: sessile, generally alternate, generally obovate to spoon-shaped. Inflorescence: terminal, generally raceme- to panicle-like. Flower: sepals, petals generally 5, free to fused at base, sepals < petals, obtuse to long-tapered; petals erect to spreading; stamens 8 or 10, in 2 whorls, epipetalous or not; pistils 4--5, free or fused below. Fruit: free or fused at base, erect or spreading. Seed: many, elliptic, often winged at both ends.
Species In Genus: +- 450 species: temps, tropical mountains, North America, Mexico, Central America, Europe, Asia, northern and eastern Africa, Atlantic islands, Indian Ocean islands; cultivated as ornamental, green roofs. Etymology: (Latin: to assuage, from healing properties of houseleek, to which Sedum was sometimes applied) Note: Sedum roseum moved to Rhodiola.
