    Acanthaceae (part 1), Kaj Vollesen, Flora of Tropical East Africa, 2008

    Habit
    Procumbent perennial herb; stems up to 20 cm long, with a narrow band of finely sericeous hairs.
    Leaves
    Leaves: lamina lanceolate, largest 2.5–4 × 0.3–0.5 cm, margin entire, glabrous.
    Inflorescences
    Spikes solitary, dispersed whole when mature; bracts purplish brown, ovate to elliptic, puberulous and ciliate, with a reflexed tip about half the length of the bract, this tip ending in a bristle and on each side without or with 1–2(–5) smooth or indistinctly scabrid bristles 0.5–1.5 mm long; lower pair (excl. tip) 3–4 mm long, second pair 5–6 mm long, third pair 7–8 mm long, inner pair 8–10 mm long; bracteoles absent.
    Calyx
    Sepal colour and indumentum as bracts; dorsal ovate-elliptic, 10–12 mm long, narrowing gradually to the acute apex; ventral similar, 9–11 mm long, with two subulate teeth; lateral 9–10 mm long.
    Corolla
    Corolla mauve, 11–13 mm long of which the tube 4–5 mm, callus on limb without apical flanges.
    Filaments
    Filaments ± 1 mm long, ± included in tube, glabrous; appendage broadly rounded, almost as long as the 2–2.5 mm long anthers.
    Fruits
    Capsule (fide Mildbraed) ± 7 mm long.
    Seeds
    Seed (fide Mildbraed) ± 6 × 5 mm.
    Distribution
    Range: Tanzania. Range: Not known elsewhere Flora districts: T6 Range: Not known elsewhere
    Ecology
    Brachystegia woodland on sandy soil; 400 m
    Note
    Closely related to Blepharis involucrata from which it differs in being a perennial herb with smaller glabrous leaves and in the recurved bract-tip without or with 1–2(–5) short, smooth or indistinctly scabrid bristles per side. Only known from this collection. The isotype of var. pinnatispina shows all transitions from no lateral bristles on the recurved bract-tip (var. refracta) to having 1–2(–5) bristles per side (var. pinnatispina).
