Genus: YuccaView DescriptionDichotomous Key

Habit: 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.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
