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

Morphology General Habit
Erect or procumbent annual, perennial or shrubby herb, unbranched to strongly branched; stems up to 1 m long, finely sericeous or sparsely so with retrorse hairs (more rarely subglabrous or pubescent to pilose).
Morphology Leaves
Leaves drying blackish, subequal or smaller down to 1/2 of larger; lamina linear to narrowly elliptic (rarely elliptic near base), largest 5–13.5 × 0.2–1.2(–2.2) cm, margin entire or some with 1–3 teeth per side in basal part, glabrous or sparsely to densely sericeous-puberulous (rarely pilose).
Morphology Reproductive morphology Flowers
Heads globose or elongated, on upper part of stems (rarely at base); sessile or peduncle up to 1 cm long, sericeous (rarely puberulous); axes sericeous or sericeous- puberulous, without or with sparse (rarely dense in T 8) stalked capitate glands; floral leaves and outer bracts lanceolate to narrowly ovate or narrowly elliptic, up to 2(–4) cm long, sericeous-puberulous and with few to many capitate glands; inner bracts similar or elliptic, up to 1.8 cm long.
Morphology Reproductive morphology Flowers Calyx
Sepals puberulous to pubescent, with few to many glands, ciliate; dorsal ovate-elliptic with long ligulate apical part (in annual plants slightly spathulate and narrowed below apex), 18–26 mm long, apex acute to truncate, 3-toothed and sometimes with 1(–2) lateral teeth per side; ventral elliptic, not ligulate, 15–22 mm long, usually deeply bifid, usually with central tooth and always with 1–2 lateral teeth per side; lateral 14–22 mm long.
Morphology Reproductive morphology Flowers Corolla
Corolla pale blue to bright blue or mauve, (22–)25–37 mm long of which the tube (4–)6–9 mm; limb distinctly 3-lobed, below with dense brown capitate glands, callus with two large lateral ribs, central ± absent, two lateral apical flanges much larger than central.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments (5–)6–10 mm long, glabrous; appendage (1.5–)2–3 mm long, obtuse or tapering to an obtuse tip, curved; anthers 4–6 mm long.
Morphology Reproductive morphology Fruits
Capsule ± 1 cm long.
Morphology Reproductive morphology Seeds
Seed not seen.
Distribution
Range: Mozambique Range: Tanzania. Flora districts: T3 T6 T8 Range: Mozambique
Ecology
Brachystegia woodland, usually on loamy soil, coastal bushland and grassland, riverbanks; near sea level to 500(–900) m
Note
But it dries blackish and has the corolla callus typical of B. affinis. It has very long floral leaves, and in some respects approaches Blepharis stuhlmannii. Bidgood et al. 430 from the foothills of the Nguru Mts is from much higher altitude (900 m) than the rest of the material. In most of its area Blepharis affinis is easily distinguished by the perennial habit, appressed indumentum, leaves drying blackish and the inflorescences towards tip of the stems. An extreme form from T 8 is represented by Issa 116 and Migeod 20: a small ephemeral herb with inflorescences in the axils of the cotyledons, but with large corolla and appressed indumentum. These specimens differ mainly from B. panduriformis in the larger corolla and usually entire leaves, but there are also differences in the shape of the ribs and flanges of the callus on the corolla limb (see descriptions). The indumentum here is often spreading, the annual habit is more common as are inflorescences towards the base of the stems, and the upper sepal is often slightly spathulate. But in T 8 some specimens become ± intermediate with B. panduriformis.
