The isolated lineage of Chenopodium polyspermum L., revealed in the phylogenetic study of Fuentes-Bazán & al. (2012b), is well supported by the unique morphological characters of that widespread Eurasian species, which led to the creation of a monotypic subsection within Chenopodium s.l. (Mosyakin & Clemants 1996).A


Annual, non-aromatic herbs, glabrous. Stems erect to ascending or prostrate, branched, lower branches subopposite, long. Leaves alternate, petiolate; blade thin, ovateelliptic; margin entire. Inflorescence leafy and bracteate,
composed of large, loose axillary dichasia or sometimes
more condensed glomerules arranged spicately. Flowers
bisexual or pistillate; perianth unchanged in fruit, segments
(4 – )5, free near to the base, with membranous margins, not-keeled, spreading in fruit; stamens 1 – 3( – 5); stigmas 2. Fruits with membranous pericarp, free. Seeds horizontal, compressed-globose, round in outline, margin fairly obtuse, testa brown to blackish, undulately striate.B
