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

    Type
    Type: Tanzania, Uzaramo, Stuhlmann 6711 (B†, syn.; BM!, lecto.; W!, isolecto.)
    Habit
    Perennial (rarely annual) herb or shrublet, 10–30 cm tall, sometimes sending up annual shoots after burning
    Stem
    Stems erect, simple or ± branched, crisped- to patentpubescent
    Leaves
    Leaves alternate, shortly petiolate, elliptic to obovate, 10–50(–90) × (5–)10–25(–40) mm, rounded to subacute, base cuneate to rounded, sparsely to densely pubescent, mainly on the veins and margin; petiole 0.5 mm, pubescent
    Flowers
    Flowers greenish-white, in ± congested lateral racemes 1–2.5 cm long; rachis pubescent; bracts and brateoles similar, linear-lanceolate, 1–1.3 mm long, pubescent, persistent; pedicels 1.5–2.5 mm, pubescent
    Calyx
    Posterior sepal keel-shaped, 2.5–3.5 mm long, pubescent; wing sepals obliquely elliptic, (4.5–)5–7 × 2.5–3.5(–4) mm, pubescent to glabrous; anterior sepals keel-shaped, 2–2.5 mm long, pubescent, free
    Corolla
    Upper petals obliquely obovate-elliptic, 2–2.25 mm long; carina 3.5–4 mm long; crest ± 1.5 mm long, fimbriate
    Stamens
    Stamens 8
    Fruits
    Capsule obovate to suborbicular in outline, (3–)4–6.5 × 3.5–5 mm, ciliolate and broadly winged (wing ± 0.5 mm wide)
    Seeds
    Seeds ovate or elliptic in outline, 2.5–4 × 1.5–2 mm, sericeous; caruncle 0.5–0.7 mm long, with three appendages 0.7–2(–2.5) mm long
    Figures
    Fig 4: 6, p 10
    Ecology
    Riverine forest and bushland, forest margin, grassland, often on ‘black cotton’ soils; 10–2500 m
    Note
    I do not know what P. erlangeri is; but I do know that it cannot be in subsection Eriopterae ( = Blepharidium), where Chodat puts it, because of the original description of the wings; it is in subsection Tinctorieae or Asiaticae. The material from Somalia and Kenya which Thulin in Fl. Somalia 1: 84 (1993) calls P. erlangeri is a different taxon ( P. kajii Paiva), occurring in Somalia, Kenya and Tanzania, and not in Ethiopia. The type of P. erlangeri mentioned by Thulin, loc. cit., and by Gilbert in Fl. Eth. 2,1: 180 (2000) is probably either P. obtusissima or P. sadebeckiana. The type [Tanzania, Usagara, Madessa, Stuhmann 8112 (B†, holo.)] of P. cryptantha Chodat [in Engl. E.J. 48(1–2): 311 (1912); T.T.C.L.: 456 (1949); Paiva in Fontqueria 50: 307 (1998)] has disappeared and there are no duplicates. It is almost certainly P. sadebeckiana Gürke. The type of P. erlangeri Gürke ( Ellenbeck 1984, from Ethiopia) has been destroyed at B. So
