CRASSULACEAE

STONECROP FAMILY

Annual to subshrubs, fleshy
Leaves generally simple, generally basal and cauline, alternate or opposite, generally reduced upward
Inflorescence: generally cyme, generally bracted
Flower: sepals generally 3–5, generally ± free; petals generally 3–5, ± free or fused; stamens = to >> sepals, free or epipetalous; pistils generally 3–5, simple (sometimes fused at base), ovary 1-chambered, placenta 1, parietal, ovules 1–many, style 1
Fruit: follicles generally 3–5
Seeds 1–many, small
Genera in family: ± 30 genera, ± 1500 species: ± worldwide, especially dry temp; many cultivated for ornamental. Family description and generic key by Melinda F. Denton and Reid Moran.

DUDLEYA

Jim A. Bartel

Perennial, fleshy, glabrous
Stem generally caudex or corm-like, generally vertical, branched or not, generally covered with dried leaves or leaf bases
Leaves in basal rosettes, evergreen vernal and ephemeral
Inflorescence: cyme, axillary, 1-sided; bracts leaf-like, alternate
Flower: sepals 5, fused below; petals 5, fused at base, erect to spreading above; stamens 10, epipetalous; pistils 5, ± fused below
Fruit: follicles 5, erect to spreading, many-seeded
Seed < 1 mm, narrowly ovoid, brown, striate
Species in genus: ± 45 species: sw North America
