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

    Habit
    Trailing or straggling perennial herb with several stems from a woody rootstock; stems up to 35 cm long, puberulous to sericeous.
    Leaves
    Leaves: lamina lanceolate to narrowly ovate or narrowly elliptic, largest 5–7 × 0.5–1.5 cm, margin entire, glabrous to sparsely scabrid-pubescent.
    Inflorescences
    Spikes in dense terminal clusters of 2–8(–16) or some solitary, persistent, each subtended by a whorl of small bract-like leaves; bracts straw-coloured to dark brown, obovate or narrowly so, puberulous to pubescent, terminating in a recurved bristle and on each side with 5–7 finely retrorsely scabrid (pilose near base) and finely glochidiate bristles (2–)3–7 mm long; outer pair 6–9 mm long, second pair 8–13 mm long, third pair 12–16 mm long, inner pair 16–20 mm long; bracteoles absent.
    Calyx
    Sepals puberulous and ciliate, colour as bracts; dorsal elliptic, 23–26 mm long, apical part somewhat ligulate, apex subacute to rounded with 1–3(–5) small teeth; ventral ovate-elliptic, 19–23 mm long, with two acute teeth 2–7 mm long; lateral 12–16 mm long.
    Corolla
    Corolla creamy white to pale violet, 27–33 mm long of which the tube 6–8 mm; callus 3-ribbed apically and with 3(–4) distinct apical flanges.
    Filaments
    Filaments 8–9 mm long, sparsely glandular near apex; appendage 1–2 mm long broadly rounded; anthers 3.5–5 mm long.
    Fruits
    Capsule and seed not seen.
    Ecology
    Brachystegia woodland on sandy to stony soil and on rocky outcrops; 1500–1800 m
    Note
    Napper (l.c.) says that this taxon is only slightly different from Blepharis cuanzensis from W Angola, Zambia and SW Congo. But there are in actual fact so many differences that the two must be treated as distinct species. In B. tanganyikensis the flowers are in dense clusters, the sepals are short, the corolla is white to pale violet with the limb uniformly hairy all over the upper surface. In B. cuanzensis the corolla is bright blue or dark purple and the limb is only hairy in the central part.
