    Rubiaceae, B. Verdcourt. Flora Zambesiaca 5:1. 1989

    Habit
    A rather coarse erect mostly sparsely branched annual herb 10–60 cm. tall, the stems often reddish or pinkish, 4-angled, hairy below the nodes.
    Leaves
    Leaf blades 2.5–6 cm. x 3–8 mm., linear-lanceolate, acute at the apex, mostly broadened at the base, pubescent or ± scabrid above with white hairs and with longer white hairs beneath, particularly or sometimes only on the broadened base; stipule bases 1–2 mm. long, hairy, with 7 setae 0.2–1.5 cm. long.
    Flowers
    Flowers (3)4-merous, congested into usually quite large axillary heads 0.5–2 cm. wide, usually made up of normal axillary clusters together with those at the nodes of much reduced axillary shoots, the whole coalescing, each compound inflorescence thus supported by numerous leaves and also with leaves emerging from its centre; bracteoles very numerous, reddish-brown, 3 mm. long; pedicels 0.5 mm. long.
    Calyx
    Calyx tube 1.4 mm. long, ellipsoid; lobes 4, 1–2 mm. long, linear-lanceolate or slightly spathulate, scabrid on the margins.
    Corolla
    Corolla white or pale mauve; tube narrowly cylindrical with upper quarter funnel-shaped and c. 4 rimes as wide as basal part of tube, altogether 1.3 mm. long; lobes 0.8 x 0.4 mm., ovate-elliptic.
    Filaments
    Filaments exserted 0.6 mm.
    Pistil
    Style exserted 0.7 mm.; stigma with long papillae.
    Fruits
    Capsule 2.5 mm. long, oblong-ellipsoid, hairy at the apex.
    Seeds
    Seeds chestnut-brown, very shiny, 1.8–2.2 x 0.8–0.9 x 0.5 mm., narrowly oblong-ellipsoid, with a deep ventral groove but ± no sculpture.
