    Stem
    Stem erect or decumbent, up to 30 cm tall
    Leaves
    Leaves acid tasting, in a basal rosette as well as along the stems; lamina (0.7)1.5–6 × 0.5–2.5 cm, linear-ovate to ovate, acute at the apex, often hastate or sagittate with spreading or forward-pointing lobes, more rarely cuneate or rounded at the base, petiolate; petiole up to 4(12) mm long
    Ocrea
    Ocrea 4–5 mm long, hyaline, silvery, lacerate at the apex
    Flowers
    Flowers pedicellate, in whorls up to 5 mm in diameter in the axil of hyaline bracts, arranged in racemes; racemes ± lax and branched forming terminal panicles, leafless or nearly so Male flowers 2–2.5 mm in diameter; outer perianth segments 1.25–1.75 × 0.5–0.75 mm, oblong-lanceolate, the inner (0.7)1–2(2.5) × 0.6–1.3(1.8) mm, greenish-brown, becoming tinged with red; anthers up to 1.5 mm long, yellow, longer than filaments
    Perianth
    Outer perianth segments of female flowers up to 1 × 0.75 mm, acute, greenish, with a membranous margin, the inner closely appressed to and slightly accrescent with the nut
    Fruits
    Nut light brown, (1)1.2–1.5(1.7) × 0.8–1.2(1.5) mm, sharply trigonous, ± wrinkled and papillose.
    Ecology
    Common weed in cultivated lands, grasslands, in wet places and sandy banks of watercourses; 1500–2000 m.
    Note
    Wild (1955) notes as of importance as a weed only in the eastern border region of Zimbabwe. Subsp. angiocarpus is recognized by its mature inner perianth segments joined to the nut. This character is ± conspicuous in all the female specimens examined, except Fries, Norlindh & Weimarck 3463 (K) from Nyangani Mt., in which the segments are not clearly adnate.
    Distribution
