    Amaranthaceae, C. C. Townsend. Flora Zambesiaca 9:1. 1988

    Habit
    Annual herb, erect, simple or branching from near the base upwards, (8) 30–120 (180) cm.
    Stem
    Stem and branches green to reddish, sulcate or striate, glabrous or with short, few-celled hairs especially about the nodes.
    Leaves
    Leaves narrowly lanceolate to broadly ovate, occasionally (mostly in S. Africa) with a broad, obtuse lateral lobe on each side near the base, acute to acuminate, glabrous or with short, few-celled hairs on the inferior surface about the base; lamina of main stem leaves (1) 2–8.5 (10) × (0.4) 1–4 (5) cm., subcordate to truncate or attenuate below, the lower margins often scabrid, more or less decurrent along the slender, up to more or less 5 cm. long petiole; superior and branch leaves smaller and often narrower, more shortly petiolate; all leaves often fallen by the fruiting stage.
    Inflorescences
    Inflorescences axillary and terminal, simple or branched spike-like thyrses more or less 6.5–35 cm. long, formed of distant or (at least above) approximate, few-to many-flowered lax or congested and subglobose, white or pinkish clusters 2–20 (30) mm. in diam., in well-grown individuals the superior leaves much reduced so that a terminal panicle is formed; inflorescence axis glabrous or furnished with multicellular hairs.
    Bracts
    Bracts and bracteoles ovate to ovate-elliptic, c. 1.25–2 mm. long, scarious with a darker nerve, margins minutely (or more coarsely at the base) erose-denticulate, glabrous.
    Tepal
    Tepals ovate-elliptic, 1.75–2.75 mm. long, shortly mucronate with excurrent midrib, glabrous, scarious with a narrow less translucent band along the midrib, margins minutely denticulate at least above.
    Androecium
    Free portion of filaments subequalling the sheath, sinuses rounded with no intermediate teeth; anthers reddish.
    Stigma
    Stigmas 2–3, longer than the very short style; ovary 6–8-ovulate.
    Fruits
    Capsule ovoid, 1.75–2.25 mm. long, included or a little exserted, rounded and not thickened at the apex.
    Seeds
    Seeds c. 0.75 mm. in diam., compressed, black, shining, with a rather fine reticulate pattern, the areolae only slightly convex.

    Habit
    Annual herb, erect, simple or branching from near the base upwards, (8–)30–120(–180) cm.
    Stem
    Stem and branches green to reddish, sulcate or striate, glabrous or with subscabrid, short, few-celled hairs especially about the nodes.
    Leaves
    Leaves narrowly lanceolate to broadly ovate, acute to acuminate, glabrous or with short few-celled hairs on the lower surface about the base; lamina of the leaves from main stem (10–)20–85(–100) × (4–)10–40(–50) mm., subcordate to truncate or attenuate below, the lower margins often scabrid, ± decurrent along the slender, up to ± 5 cm. petiole; upper and branch leaves smaller and often narrower, more shortly stalked; all leaves often deciduous by the time of fruiting.
    Inflorescences
    Inflorescences axillary and terminal, simple or branched spike-like condensed thyrses ± 6.5–35 cm. long, formed of distant or (at least above) approximate few-many-flowered lax or congested and subglobose white or pinkish clusters 2–20(–30) mm. in diameter, in well-grown individuals the upper leaves much reduced so that a terminal panicle is formed; inflorescence-axis glabrous or sparingly furnished with multicellular hairs.
    Bracts
    Bracts and bracteoles ovate to oval-elliptic, ± 1.25–2 mm., scarious with a single nerve, margins minutely (often more coarsely at the base) erose-denticulate, glabrous.
    Perianth
    Perianth segments oval-elliptic, 1.75–2.75 mm., shortly mucronate with the percurrent single nerve, glabrous, scarious with a narrow less translucent vitta along the nerve, margins minutely denticulate, at least above.
    Stamens
    Free portion of filaments subequalling the sheath, sinuses rounded with no intermediate teeth; anthers red.
    Stigma
    Stigmas 2–3, longer than the very short style.

    Seeds ± 0.75 mm., compressed, black, shining, with a rather fine reticulate pattern, the areolae being only very slightly convex.
    Habitat
    Most frequently as a weed of abandoned or currently cultivated arable land, also in forest clearings, along woodland paths and roadsides, in short grassland or on damp ground by rivers; 1–1500 m.
