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

    Erect to procumbent annual herb (most often erect and single-stemmed); stems up to 45(–75) cm long, pilose or sparsely so with shiny many-celled hairs and with a band of puberulous hairs.
    Leaves with the subequal or smaller down to 2/3 of larger; lamina linear to narrowly ovate or narrowly elliptic, largest 4–11 × 0.3–1.1 cm, margin on some or all with 1–4 teeth per side in basal half, subglabrous to sparsely pilose, densest above and along veins beneath, scabrid above.
    Heads usually elongated, usually only near base of stems; peduncle up to 1.5(–3) cm long, puberulous to pubescent; axes finely sericeous-puberulous, usually with stalked capitate glands; floral leaves and outer bracts lanceolate to narrowly elliptic, up to 4(–7) cm long, indumentum similar, with capitate glands; inner bracts similar or elliptic, up to 1.4 cm long, with capitate glands.
    Sepals with similar indumentum, distinctly ciliate; upper ovate-elliptic, 16–23 mm long, with a long ligulate-spathulate apical part distinctly narrowed below apex, apex subacute to truncate or retuse, 1–3-toothed; lower ovate-elliptic, 12–17 mm long, not ligulate, bifid, usually also with central tooth and a single lateral tooth per side; lateral 13–18 mm long.
    Corolla pale blue to bright blue or mauve (rarely white), 20–30 mm long of which the tube 4–6 mm; limb distinctly 3-lobed, below with many long-stalked capitate glands, callus with 3 equally strong ribs and 3 large apical flanges.
    Filaments 4–7 mm long, glabrous; tooth 2.5–4 mm long, tapering to an obtuse tip, curved; anthers 3.5–5 mm long.
    Capsule 7–9 mm long.
    Seed ± 6 × 4 mm.
    Acacia-Commiphora bushland on sandy to loamy or clayey soil, grassland on black cotton soil, roadsides; 600–1500 m
    A common and often dominant element of the early dry season flora in the Acacia bushlands of Central Tanzania where it can sometimes be so plentiful that it suffuses the ground with a pale blue colour. See also note after B. affinis. The more vigorous of these get a strong superficial resemblance to B. stuhlmannii, but are always immediately recognisable by the characteristic dorsal sepal. Plants which continue to grow into the dry season get larger, more branched and eventually get almost woody stems. In its typical form Blepharis panduriformis is an unbranched or sparsely branched erect herb, but occasionally decumbent plants occur, sometimes mixed with the normal erect plants.
