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

Morphology General Habit
Erect to decumbent unbranched annual herb; stems up to 25 cm long.
Morphology Leaves
Leaves subequal, sparsely pilose with many-celled hairs, finely scabrid on margins; lamina lanceolate, largest 4–14 × 0.4–1 cm, margin of all entire or a few with a single tooth near base, pilose with long many-celled shiny hairs.
Morphology Reproductive morphology Flowers
Heads all in axils of cotyledons (rarely also in axils of first leaf-pair), subsessile; axis sericeous; floral leaves and outer bracts lanceolate or narrowly oblong, up to 3 cm long, sparsely to densely pilose with long many-celled hairs, no capitate glands; inner bracts 14–17 mm long, narrowly oblong.
Morphology Reproductive morphology Flowers Calyx
Sepals with similar indumentum, finely ciliate; dorsal ovate, 15–18 mm long, narrowing gradually to the cuspidate apex, no lateral teeth; lower similar, 15–17 mm long, with 2 acuminate teeth; lateral 13–15 mm long.
Morphology Reproductive morphology Flowers Corolla
Corolla mauve to blue or dark blue, 14–18 mm long of which the tube 3–5 mm; limb ± 7 mm wide, distinctly 3-lobed, callus with 3 distinct apical flanges.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments 3–4 mm long, glabrous; tooth ± 1 mm long, rounded, tip curved in towards anther; anthers 2.5–3 mm long.
Morphology Reproductive morphology Fruits
Immature capsule ± 7 mm long.

Seed not seen.
Figures
Fig. 18, 11–17.
Ecology
Open Acacia bushland and grassland on damp pale orange sandy loam or on grey crumbling clay; 1150–1400 m
Note
A very striking species related to Blepharis longifolia but no doubt distinct. It could be interpreted as a neotenous form of B. longifolia with the heads produced in the axils of the cotyledons, but it also differs from B. longifolia in the spreading pilose indumentum and in the smaller flowers. This is quite a widespread micro-habitat in central Tanzania, and the species has probably been overlooked. It grows mainly in the transition zone between ridgetop Brachystegia woodland and Acacia valley bottom grassland.
