Key to Agavaceae
Shrub- or tree-like, generally branched from woody caudex, occasionally dying after fruiting. Leaf: rosette basal or at branch tips, 2–15 dm, linear, thick, ± rigid, stout-spine-tipped, bases ± expanded, margins generally curved up, entire or dentate, often fibrous-shredding. Inflorescence: panicle [raceme], erect (pendent), dense; peduncle generally < 2 cm wide; bracts generally ascending. Flower: generally pendent, 3–13 cm; perianth parts 6 in 2 whorls, generally ± fused, ± white, fleshy, waxy; stamens 6, filaments ± thick, fleshy; ovary superior, 3(6)-chambered, generally green, style short, often thick, poorly defined, stigmas 3-lobed, white to pale green. Fruit: berry-like or generally capsule, erect or pendent, tardily septicidal or generally indehiscent. Seed: ± many in 2 rows per chamber, often flat, black.Key to Yucca
± 40 species: eastern coastal plain, southeastern, sc, & especially dry southwestern North America; northern, central-western Mexico, northern Central America. (Haitian: yuca or manihot, because young inflorescences occasionally roasted for food) Pollinated at night by small moths while laying eggs in ovary. Yucca whipplei moved to Hesperoyucca.
