    Annual herb, (12–)15–50(–70) cm., simple or with ascending branches from near the base; stem and branches glabrous or very sparingly pilose, with pale ridges.
    Leaves
    Leaf-blade narrowly linear to broadly ovate or rarely subrotund, (1.2–)2–6(–9) × (0.2–)0.6–3(–5) cm., glabrous or the petiole and principal veins of the lower surface of the leaf spreading hairy, acute or acuminate at the apex, gradually or (in broader-leaved forms) rapidly narrowed to the base; petiole slender, in the lower leaves up to ± 5 cm., shorter in the upper leaves.
    Inflorescences
    Flowers in long and slender, or shorter and denser long-pedunculate axillary racemes, up to ± 30 cm. long, laxer below; peduncles slender, the lower up to ± 14 cm., both they and the inflorescence axis glabrous or sparingly spreading hairy; bracts persistent, ovate-lanceolate, acuminate, 1–2.75 mm., glabrous, membranous with a green or brownish percurrent midrib, each subtending a sessile or subsessile partial inflorescence of 3 flowers.
    Flowers
    Flowers glabrous, white tinged with pink to carmine or red, more rarely greenish white. Central flower fertile:2 firm navicular outer perianth-segments ± 3–4.5 mm. long, oval or oblong, 3–12-nerved, acute, mucronate; the 2–3 inner segments slightly shorter, more delicate, blunt or erose, 1–3-nerved, hyaline with a darker central vitta; stamens subequalling or shorter than the style; style ± 1.5–4 mm., the 2 stigmas finally recurved. Lateral flowers appressed, 1-bracteolate, bracteoles similar in form to the bract, these flowers much reduced and increasingly so in the upper part of the spike (sometimes absent), modified into accrescent antler-shaped scales, scales with the lateral lobes narrow to broad and wing-like.
    Fruits
    Fruit subglobose, slightly compressed, 2–2.5 mm., bluntly keeled along each side, furnished throughout with verrucae or ridges, surmounted by a thick circular rim or a corona of short firm processes; style persistent.
