LILY FAMILY

Dale W. McNeal, except as specified

Perennial to trees, from membranous bulb, fibrous corm, scaly rhizome, or erect caudex
Stem generally underground
Leaves generally basal, often withering early, alternate, generally ± linear
Inflorescence various, generally bracted
Flower generally bisexual, generally radial; perianth often showy, segments generally 6 in two petal-like whorls (outer sometimes sepal-like), free or fused at base; stamens 6 (or 3 + generally 3 ± petal-like staminodes), filaments sometimes attached to perianth or fused into a tube or crown; ovary superior or inferior, chambers 3, placentas generally axile, style generally 1, stigmas generally 3
Fruit: generally capsule, loculicidal or septicidal (berry or nut)
Genera in family: ± 300 genera, 4600 species: especially ± dry temp and subtropical; many cultivated for ornamental or food; some TOXIC. Here includes genera sometimes treated in Agavaceae, Amaryllidaceae, and other families.

ALLIUM

ONION, GARLIC

Perennial with onion odor, taste; bulb solitary or on rhizomes, reforming each year, divides at base into daughter bulbs, outer bulb coats generally brown or gray, cell sculpture generally important to identification, inner bulb coats generally white

Flower: perianth segments 6, in 2 petal-like whorls; stamens 6, epipetalous, filaments wide at base, fused into a ring; ovary superior, sometimes with 3 or 6 crests, chambers 3, ovules generally 2 per chamber, style 1, stigma entire or 3-lobed
Fruit: capsule, loculicidal
Seed obovoid, black, sculpture net-like, smooth, or granular
Species in genus: 500 species: worldwide, especially CA
Etymology: (Latin: garlic)
