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.
