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

Morphology General Habit
Erect or procumbent annual herb; stems up to 60 cm long, subglabrous to densely scabrid-puberulous when young.
Morphology Leaves
Leaves: lamina linear to lanceolate or narrowly elliptic, largest 2.5–12 × 0.3–1.2 cm, margin entire to sinuate-dentate, scabrid-puberulous or sparsely so, below also with longer hairs on midrib.
Morphology Reproductive morphology Inflorescences
Spikes terminal (in larger plants seemingly axillary due to development of lateral branches), 1–9(–12) cm long; peduncle 0–1(–2.5) cm long, with 1–2 pairs of small sterile bracts; fertile bracts elliptic to slightly obovate, 1.2–3.8 cm long, narrowing abruptly to a recurved pungent tip of 1/3–1/2 the total length, each side with 3–8 straight teeth 1–7 mm long, pubescent to pilose or sparsely so (rarely puberulous) on veins, puberulous or sparsely so between; bracteoles 7–17 mm long, puberulous and with long pilose hairs.
Morphology Reproductive morphology Flowers Calyx
Sepals pubescent to pilose; dorsal ovate to elliptic with ligulate apical part, 10–18 mm long, 5-veined, apex truncate with 1–3 teeth; ventral elliptic or oblong, 8–12 mm long, 5-veined; lateral 5–9 mm long.
Morphology Reproductive morphology Flowers Corolla
Corolla bright blue or bluish mauve, with darker veins; tube 2–4 mm long; limb (9–)12–20(–23) mm long.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filaments 4–8 mm long, anterior pair hairy at base; appendage 3–5 mm long, as long or longer than the 2–4 mm long anthers.
Morphology Reproductive morphology Fruits
Capsule 7–9 mm long.
Morphology Reproductive morphology Seeds
Seed ± 5 × 5 mm.
Figures
Fig. 16.
Distribution
Range: Tanzania. Range: West Africa to Ethiopia and Somalia, north to Egypt and through Arabia and Iran to NW India Range: Kenya. Flora districts: U1 K1 K2 K3 K4 K6 K7 T2 T3 T6 T7 Range: West Africa to Ethiopia and Somalia, north to Egypt and through Arabia and Iran to NW India Range: Karamoja District: near Moroto, 28 Oct. 1939, Range: Uganda.
Ecology
Dry Acacia-Commiphora bushland, Acacia bushland and grassland, semidesert scrub, lava outcrops, hardpans, often on alkaline or saline soils; 150–1450 m
Note
Through the rainy season (and into the dry where moisture prevails) the plants continue to grow and become increasingly branched, in the end producing large procumbent plants with thick semi-woody stems up to 60 cm long. Blepharis edulis shows an enormous plasticity. Plants from the beginning of the rainy season (or in dry years) are small and often only have a single spike.

Morphology General Habit
Annual or perennial herb or occasionally subshrub; stems erect to prostrate, up to 50 cm long, glabrous to pubescent
Morphology Leaves
Leaves lanceolate to ovate, elliptic or obovate, up to 1.5–9(–14) x 0.3–1.4(–1.7) cm, glabrous to pubescent on both sides, margin with 3 to many spreading teeth
Morphology Reproductive morphology Inflorescences
Spikes 1.5–14(–22) cm long, 4–50-flowered; peduncle c. 5–50 mm long; fertile bracts green to glaucous, glabrous to densely puberulous and usually also with longer hairs, narrowly to broadly ovate, 12–57 x 6–18(–20) mm, with a straight to recurved spinose 5–28(–32) mm long tip, and with (3–) 4–8(–10) spines up to 3–8(–10) mm long on each side; bracteoles 7–14(–18) x 1–2 mm
Morphology Reproductive morphology Flowers Calyx
Calyx ± densely pubescent, the upper lobe ± broadly ovate-elliptic, (9–)12–19(–21) mm long, 5–7-veined from the base, 3-toothed at the apex, the lower lobe (6–)8–14(–16) mm long, with 2 teeth at the apex
Morphology Reproductive morphology Flowers Corolla
Corolla blue, mauve or purple, (15–)17–27(–30) mm long; tube 3–7 mm long; limb 8–16(–18) mm wide.
Distribution
N1–3; C1, 2; S1–3 Djibouti, Eritrea, Ethiopia, Sudan, Uganda, Kenya, Tanzania and westwards to Mauritania, also on the Arabian Peninsula and eastwards to Iran.
Ecology
Altitude range 0–1400 m.
Note
This is an exceedingly variable species and plants in dry places or from the beginning of the rainy season may be very small with often a single spike only, whereas under more favourable conditions large, procumbent, branching plants may develop.
