    Polygalaceae, Jorge Paiva. Flora of Tropical East Africa, 2007

    Type
    Type: Congo-Kinshasa, Katanga, Kundelungu, Kassner 2771 (B†, holo.; K!, lecto.; BM!, BR!, E!, P!, isolecto.)
    Habit
    Annual herb, 1–3 m tall
    Stem
    Stems erect, simple or few-branched, sparsely pilose, mainly on the young parts, or glabrous
    Leaves
    Leaves alternate, shortly petiolate (petiole 0.5–1 mm), linear and grass-like to very narrowly elliptic, 3–25 × 0.3–1.8(–2) cm, acute, base cuneate, slightly rough with short hairs, mainly on the upper surface, to glabrescent
    Flowers
    Flowers purple to whitish, in many-flowered simple or few-branched terminal racemes up to 60 cm long, rachis pilose; bracts ovate-lanceolate, 4–10 × 0.5–1.5 mm, caudate with a thread-like apex, persistent; bracteoles ovatelanceolate, 2.5–3 × 0.5–1 mm, persistent; pedicels 5–14 mm, pilose
    Calyx
    Posterior sepal keel-shaped, 4.5–6.5 × 3–4 mm, pilose; wing sepals obliquely suborbicular, (9–)10–13.5 mm in diameter, glabrous or minutely ciliate; anterior sepals keelshaped, 4–6 × 3–4 mm, pilose, free
    Corolla
    Upper petals obliquely elliptic, 5–7 × 3–4 mm; carina 8.5–11 mm long; crest 3–4 mm long, fimbriate
    Stamens
    Stamens 8
    Fruits
    Capsule oblongobovate in outline, 8–11 × 5.5–7.5 mm, winged, wing 0.5–0.8 mm wide, ciliate
    Seeds
    Seeds cylindric, 3.2–4(–6) × 1.8–2 mm, with white silky hairs ± 2 mm long, exceeding the base of the seed; caruncle subsymmetric, kidney-shaped, with three very short appendages.
    Ecology
    Open woodland and wooded grassland, sometimes in marshes; 600–2500 m
    Note
    I did not find the type [Tanzania, Kiriba, Scott-Elliot 8287 (B†?, holo.)] of P. elliottii Chodat [in Engl. E.J. 34: 199 (1896); Paiva in Fontqueria 50: 308 (1998)], but I am almost certain that it is conspecific with P. macrostigma Chodat. If so, P. elliottii Chodat [in Engl. E.J. 34: 199 (1896)] has priority over P. macrostigma Chodat [in E.J. 48(1–2): 319 (1912)]
