Key to Agavaceae
Shrub-like, stem often short, forming basal rosettes, scapose, often rhizomed, generally dying after flowering. Leaf: long-lived, sessile, lance-linear to ovate, thick, generally rigid, often fleshy, glabrous, armed with marginal teeth, spine at tip. Inflorescence: panicle-, raceme-, or spike-like, bracted, often with bulblets. Flower:  paired, or in clusters of 3–40; perianth generally funnel- or bell-shaped, yellow to green-yellow, parts petal-like, 6 in 2 whorls, fused basally, lobes erect to ascending or ± spreading distally; stamens 6; ovary inferior, 3-chambered.
