Project data     (Last Modified On 10/28/2015)
Area distribution :

The family is almost cosmopolitan but largely centred in arid regions, mostly on saline soils. It comprises more than 100 genera, and at least 1,600 species.

Notes :

Some modern taxonomists (e.g. Mabberley, 2008) include the Chenopodiaceae in the Amaranthaceae, as based on morphological, chemical, physiological and molecular similarities. We prefer to leave the two families apart (as in Heywood & al., 2007), if only for practical reasons. The Chenopodiaceae is one of the largest families in the Flora Palaestina. All subfamilies in its recent circumscription (Betoideae, Camphorosmoideae, Chenopodioideae, Salicornioideae, Salsoloideae, Suaedoideae), except for the Corispermoideae, are represented in our flora. Since there are several, different and complex, phylogenetic/systematic approaches to this family, we have preferred to arrange the taxa more or less as presented in the first edition of the Flora Palaestina. However, certain genera are located according to the new sectional subdivision (see literature below). Included in our Flora are 32 genera out of about 100 genera. Many species occupy desert habitats, saline marshes, or are ruderals, and often feature C4 photosynthesis (e.g in some Chenopodioideae like Atriplex, Camphorosmoideae, Salsoloideae and Suaedoideae).

Annual or perennial herbs or shrubs, rarely trees, often more or less succulent. Leaves usually alternate, sometimes opposite, diverse in shape, often fleshy and terete or reduced to scales, exstipulate. Flowers small, hermaphrodite or unisexual, solitary or in clusters or in spicate or paniculate inflorescences, often supported by bract and two bracteoles, actinomorphic. Perianth greenish, whitish or (rarely) coloured, persistent, of 3-5 free or connate tepals, rarely 0, unchanged or accrescent in the fruiting stage, sometimes with wing-like projections or appendages. Stamens 1-5, opposite perianth segments, usually free, rarely united at base into a cup-like ring, sometimes reduced into staminodes between fertile stamens. Ovary usually superior, free, rarely adnate to perianth, with a single basal ovule; styles 2, rarely 3-5, free or united at base. Fruit one-seeded, mostly indehiscent, rarely dehiscent. Seeds horizontal or vertical (sometimes both positions at one individual); embryo straight, bent, or circular around perisperm or spiral. Endosperm absent; perisperm abundant or lost.
