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: CrassulaView DescriptionDichotomous Key

Habit: 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. Chromosomes: x=(7)8.
Species In Genus: +- 250 species: especially Africa, annual +- worldwide. Etymology: (Latin: diminutive of thick) Note: Crassula argentea Thunb., a synonym of Crassula ovata (Mill.) Druce, a waif.

WAIF
Habit: Shrub, rounded. Stem: many, erect, 30--50 cm, to 20 cm diam, young bark +- smooth, silvery. Leaf: cauline, generally > 4 pairs, subsessile, 20--70 mm, obovate, bright green, tip rounded, margins entire. Inflorescence: panicle, compact; pedicels 8--12 mm. Flower: parts generally in 5s; sepals erect, 1--2 mm, wide-deltate, acute; petals (5)7--10 mm, spreading, lanceolate to lance-oblong, acute, white, tinged pink. Fruit: erect, ovoid. Seed: 30--50, oblong, with rows of pointed papillae at 20×.

Synonyms: Crassula argentea Thunb.; Toelkenia ovata (Mill.) P.V. Heath
