Chenopodiaceae, J. P. M. Brenan. Flora Zambesiaca 9:1. 1988
- Morphology General Habit
- Mostly annual or perennial herbs, glabrous, pubescent, glandular or mealy with vesicular hairs.
- Morphology Leaves
- Leaves membranous to more or less fleshy, entire, toothed, or pinnately divided, alternate, mostly petiolate, normally broad.
- Morphology Reproductive morphology Flowers
- Flowers mostly in cymose clusters (“glomerules”) variously arranged but often paniculate and mixed, without bracteoles.
- Morphology Reproductive morphology Flowers Perianth
- Perianth of both sorts of flower normally (3) 4–5 lobed, unaltered or nearly so in fruit, or sometimes becoming fleshy.
- Morphology Reproductive morphology Flowers Androecium Stamens
- Stamens 1–5.
- Morphology Reproductive morphology Flowers Gynoecium Stigma
- Stigmas 2 (5).
- Morphology Reproductive morphology Fruits
- Fruit with a membranous indehiscent pericarp.
- Morphology Reproductive morphology Seeds
- Embryo annular. Seeds “horizontal” (vertically compressed) or, less commonly, “vertical” (horizontally compressed), testa normally thin, hard and brittle. Endosperm present.

- Morphology General Habit
- Annual or perennial herbs, often weedy; pubescent, glandular or mealy with white vesicular hairs or ± glabrous
- Morphology Leaves
- Leaves alternate, mostly broad and petiolate, not obviously succulent
- Morphology Reproductive morphology Inflorescences
- Inflorescences basically cymose, variously arranged, sometimes condensed into clusters, bisexual and female flowers mixed, bracteoles absent
- Morphology Reproductive morphology Flowers
- Flowers (3–)4–5-merous, perianth deeply divided, perianth segments sometimes longitudinally keeled, rarely becoming fleshy in fruit; stamens 1–5; stigmas usually 2, slender
- Morphology Reproductive morphology Fruits
- Fruit a very thin-walled utricle, pericarp closely adhering to seed
- Morphology Reproductive morphology Seeds
- Seed discoid, horizontal or vertical within fruit; testa brittle, minutely ornamented; embryo annular, endosperm present.
- Note
- Many species are variable and difficult to separate from allied taxa. This is reflected in the complex infraspecific taxonomy of many of the more widespread species, but is seem likely that at least part of this owes more to phenotypic plasticity than differences in genotypes. Identification is often dependent on seed characters, especially the microscopic ornamentation of the testa. Vegetative characters are very plastic and are often difficult to use. A difficult genus variously estimated to include from “over 70” to “perhaps 250” species, almost all weeds, some of which are subcosmopolitan.
