    Type: Congo-Kinshasa, Katanga, Senga West, Kassner 2938 (B†, holo.; BM!, lecto.; BR!, isolecto.)
    Habit
    Annual herb, 3–15 cm tall
    Stem
    Stems slender, usually pseudo-di- or trichotomously branched, apparently terminating in an inflorescence and growth continuing by lateral branches, usually exceeding the primary one, crisped-pubescent
    Leaves
    Leaves alternate, petiolate (petiole 1–2 mm, crisped-pubescent), elliptic to broadly elliptic, 10–30(–40) × (3–)5–12(–20) mm, subacute to rounded, base cuneate, glabrous or very minutely pubescent on both sides
    Flowers
    Flowers whitish, pinkish or lilac, in much congested terminal racemes, often subglobose, 7–20 mm long, rachis crisped-pubescent; bracts lanceolate, 0.7–1 mm long, usually pubescent, persistent; bracteoles lanceolate, 0.5 mm long, usually pubescent, persistent; pedicels 1.5–3 mm, usually crisped-pubescent
    Calyx
    Posterior sepal keel-shaped, 1.5–2 × 0.5–1 mm, pubescent or glabrescent; wing sepals elliptic to suborbicular, (2–)2.5–3.5 × 2–3 mm, pubescent towards the base; anterior sepals keel-shaped, 1–1.5 mm long, free
    Corolla
    Upper petals obliquely obovate, constricted below the middle, 1.5–2.2 × 0.7–1.5 mm, pubescent at the base; carina 2.5–3 × 1.2–1.5 mm; crest 0.7–1 mm long, fimbriate
    Stamens
    Stamens 8
    Fruits
    Capsule elliptic to ovate in outline, 1.5–2.5 × 1.5–2 mm, glabrous, narrowly winged (wing 0.2 mm wide)
    Seeds
    Seeds ovoid to subglobose, 1–1.8(–2) × 0.6–0.8(–1) mm, glabrous, rarely puberulous; caruncle subsymmetric, subglobose, 0.4–0.6 mm long, with the appendages hiding the caruncle, 0.4–0.5 mm long
    Figures
    Fig 5: 7, p 11
    Ecology
    Wooded grassland and grassland; 800–1700 m
    Note
    Polygala welwitschii with its two subspecies and P. melilotoides are very close, and not easy to distinguish. The seed is the most important organ to differentiate them.
    Distribution
