Perennial; bulb 1 or on rhizomes, reforming each yr; bulblets at bulb bases or on rhizomes; outer bulb coat brown, red-brown, yellow-brown, or gray; inner coats generally white (pink, red, or yellow); onion odor, taste present (except Nothoscordum).
Stem: scapose, cylindric, sometimes flat or triangular.
Leaf: basal, sheathing stem, linear [or not], cylindric, channeled or flat, generally ± withering from tip by flower.
Inflorescence: umbel (1-flowered in Ipheion), bracts generally 2, splitting and appearing 2+ or not, ± fused, enclosing flower buds, scarious.
Flower: perianth parts 6 in 2 petal-like whorls, ± free to fused in lower 1/3–1/2; stamens 6, fused to perianth, filaments widened at base, anthers attached at middle; ovary superior, 3-lobed, chambers 3, ovules 2+ per chamber, style 1, stigma entire or ± 3-lobed.
Fruit: capsule, loculicidal.
Seed: black, sculpture net-like, smooth, or granular.
13 genera, 750–800 species: worldwide. Many cultivated for food, ornamental. —Scientific Editor: Thomas J. Rosatti.
Key to Alliaceae
Outer bulb coat generally brown to gray, inner generally white.Key to Allium
Stem: scapose, cylindric, triangular in ×-section, or flat.
Leaf: basal, 1–5 per stem, linear, cylindric, channeled, or flat, generally withering from tip before flower.
Inflorescence: umbel, flowers 3–many, rarely all or in part replaced by bulblets; bracts generally 2–4, obvious, ± fused, scarious.
Flower: perianth parts ± free, generally with darker or contrasting midvein, outer generally wider; filaments fused into a ring; ovary with 0, 3, or 6 crests, ovules generally 2 per chamber.
Seed: obovoid, generally unappendaged.
700 species: generally n temperate, especially CA. (Latin: garlic) [McNeal & Jacobsen 2002 FNANM 26:224–276] Replanting bulbs after study essential for survival of plant; shape, arrangement of cells of outer bulb coat (outer bulb coat sculpture) generally important in identification, generally determined only with magnification; color of outer bulb coat may be masked by substrate; stem lengths from top of bulb to base of inflorescence, not from substrate surface.
Bulb 1–2 cm, ovoid, bulblets generally clustered at base or on slender rhizomes; outer coat cells ± square, walls wavy; inner pink to white.
Stem: 10–30 cm.
Leaf: 2, ± = stem, widely channeled, generally withered in flower.
Inflorescence: flowers 10–50; pedicels 1–2 cm.
Flower: 5–8 mm; perianth parts ± spreading, lanceolate to ovate, rigid-keeled in fruit, acuminate, entire, rose to purple (white), with a purple crescent adaxially just above base; ovary crests 6, low, triangular, dentate.
n=7,14. Dry mtn slopes; 600–2600 m. Klamath Ranges, Outer North Coast Ranges, Cascade Range, High Sierra Nevada, Outer South Coast Ranges, Southwestern California, Modoc Plateau;
