Stem: occasionally fleshy. Leaf: blade simple, generally alternate, occasionally fleshy or reduced to scales, veins pinnate; stipules 0. Inflorescence: raceme, spike, catkin-like, spheric head, axillary clusters of flowers, or flowers 1; bracts 0--5, herbaceous, generally persistent or strongly modified in fruit, wings, tubercles or spines present or 0. Flower: bisexual or unisexual, small, generally green; calyx parts (1)3--5, or 0 in pistillate flowers, free or fused basally (or +- throughout), leaf-like in texture, membranous, or fleshy, deciduous or not, often strongly modified in fruit; corolla 0; stamens 1--5, opposite sepals, filaments free, equal; anthers 4-chambered; ovary superior (1/2-inferior), chamber 1; ovule 1; styles, stigmas 1--4 (or stigmas sessile). Fruit: achene or utricle, generally falling with persistent calyx or bracts. Seed: 1, small, lenticular to spheric; seed coat smooth to finely dotted, warty, net-like, or prickly, margin occasionally winged.
Genera In Family: 100 genera, 1500 species: worldwide, especially deserts, saline or alkaline soils; some cultivated for food (Beta vulgaris subsp. vulgaris, beet, Swiss chard; Spinacia oleracea L., spinach; Chenopodium quinoa Willd., quinoa); and some worldwide, naturalized ruderal or noxious agricultural weeds. Note: Nitrophila treated in Amaranthaceae, Sarcobatus treated in Sarcobataceae. Key to genera revised by Elizabeth H.

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.
