Perennial herb; bulb 1 or on rhizomes, reforming each year; 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 flowering. 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. 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.Key to Allium
700 species: generally northern temperate, especially California. (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; outer coat often many, thickly surrounding bulb, cells ± square, polygonal, or transversely rectangular, but not forming a herringbone pattern, walls thick, wavy. Stem: 10–35 cm. Leaf: 2, 0.7–2 × stem, ± cylindric or flat. Inflorescence: flowers 5–45; pedicels 5–25 mm. Flower: 4–9 mm; perianth parts erect or spreading, oblanceolate to narrowly ovate, entire, white or pale pink; ovary crests 3, minute, 2-lobed, central, crests and upper ovary densely papillate.

Inflorescence: open; bracts 2; flowers 10–35; pedicels 10–25 mm. Flower: 6–8 mm.
n=7. Uncommon. Open, sandy slopes, ridges; 600–2100 m. Western Transverse Ranges, San Bernardino Mountains, East of Sierra Nevada, Mojave Desert. Apr–May [Online Interchange]
