Allium haematochiton


Higher Taxonomy
Family: AlliaceaeView DescriptionDichotomous Key
Common Name: ONION or GARLIC FAMILY
Habit: 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.
Genera In Family: 13 genera, 750--800 species: worldwide. Note: Many cultivated for food, ornamental.

Genus: AlliumView DescriptionDichotomous Key


Common Name: ONION, GARLIC
Habit: Outer bulb coat generally brown to gray, inner generally white. Stem: scapose, cylindric, triangular in ×-section, or flat. Leaf: basal, 1--5[12] 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.
Etymology: (Latin: garlic) Note: Replanting bulbs after study essential for survival of pl; 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.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
