LILIACEAE LILY FAMILY

Dale W. McNeal, except as noted

Perennial herb from membranous bulb or scaly rhizome. Stem: underground or erect, branched or not. Leaf: basal or cauline, alternate, subopposite, or whorled. Inflorescence: raceme, panicle, ± umbel-like or not. Flower: perianth parts 6 in 2 generally petal-like whorls, often showy; stamens 3 or 6, filaments free or ± fused to perianth, anthers attached at base or near middle; ovary superior or ± so, style 1, entire or 3-lobed. Fruit: capsule or berry. Seed: 3–many, flat or angled, brown to black.
16 genera, 635 species: northern temperate. Users strongly encouraged to protect plants by working around need to see underground parts in using keys, e.g., by trying both leads in couplets solely dependent on such characters. Muscari botryoides (L.) Mill. an historical waif in California.

Key to Liliaceae

LILIUM LILY

Mark W. Skinner

Plant from bulb-like, scaly rhizomes (called bulbs here for brevity), generally not clonal, ± glabrous; bulb scale segments 2–many, if segmented. Stem: erect. Leaf: > 12, ± whorled (often some alternate), sessile, spreading with drooping tips to ascending, generally ± elliptic; veins generally 3; stipule 0. Inflorescence: flowers axillary, 1–40+; bracts generally 2 per flower. Flower: generally radial, generally bell- or funnel-shaped; perianth parts 6 in 2 petal-like whorls, ± lanceolate, base narrowed, generally red-purple-spotted adaxially; stamens 6, generally exceeding to much exceeding perianth, anthers attached at middle (measures are after dehiscence); style 1, stigma 3-lobed. Fruit: capsule, erect, generally ± smooth, loculicidal. Seed: many, flat, in 6 stacks.
n=12.
± 100 species: northern temperate, tropical mountains of eastern Asia. (Greek: lily) Variable, hybridization common. Many species declining from habitat destruction, collecting; few thrive in gardens. Generally flowers May–Aug.
