GOOSEFOOT FAMILY

Dieter H. Wilken, except as specified

Annual to tree, sometimes monoecious or dioecious, glandular or with bead-like hairs that collapse with age, becoming scaly or powdery
Stem often fleshy
Leaves generally alternate, entire to lobed; veins generally pinnate
Inflorescence: raceme, spike, catkin-like, or spheric cluster, or flower 1; bracts 0–few
Flower: sepals 1–5, often 0 in pistillate flowers, free or fused, generally persistent in fruit; petals 0; stamens 0–5; ovary generally superior, chamber 1, ovule 1, styles 1–3
Fruit: generally utricle
Seed 1, vertical (fruit compressed side-to-side) or horizontal (fruit compressed top-to-bottom)
Genera in family: 100 genera, 1300 species: worldwide, especially deserts, saline or alkaline soils; some cultivated for food (Beta , beets, chard; Chenopodium , quinoa)
Recent taxonomic note: Recently treated in expanded Amaranthaceae
