Acanthaceae (part 2), Kaj Vollesen. Flora of Tropical East Africa. 2008

Morphology General Habit
Erect shrubby herb, 2 m tall; stems densely glandular-pubescent on upper nodes Perennial or shrubby herbs, shrubs or small trees; stems quadrangular; cystoliths conspicuous
Morphology Leaves
Leaves with petiole of stem-leaves 4–5 cm long; lamina of stem-leaves cordiform, ± 11 × 9 cm, apex cuspidate, base cordate with sinus ± 1.5 cm deep, margin grossly doubly dentate with teeth to 1 cm long, sparsely pubescent on both sides, densest along veins, with longer spreading hairs along midrib beneath Leaves opposiste, often with conspicuous “blisters” along veins beneath
Morphology Reproductive morphology Inflorescences
Inflorescence narrow, racemiform, with long branches from basal nodes, ± 12 cm long; flowers in 3-flowered cymes towards base of inflorescence, solitary upwards; bracts green and leafy towards base of inflorescence, bract like upwards, all persistent, with indumentum as leaves; branches and pedicels densely glandular-pubescent to tomentose (hairs to 2 mm long); pedicels to 3 mm long
Morphology Reproductive morphology Flowers Calyx
Calyx glandular-pubescent all over (to within 1 mm of apex of lobes); dorsal lobe ± 17 mm long, ventral and lateral lobes ± 13 mm long; lobes filiform to linear, 0.2–0.5 mm wide, subacute. Corolla white (no notes on throat and patch on lower lip), with dense band of long hairs on lower lip, sparser on lateral lobes and absent on dorsal lobes, ± 17 mm long, cylindric tube ± 1 mm long, throat ± 8 mm long; lobes all similar, elliptic, ± 8 × 6 mm; papillate area on lower lip crescent shaped Calyx 5lobed, divided almost to the base into linear-lanceolate to narrowly spathulateligulate lobes, dorsal lobe slightly to distinctly longer and wider then the rest
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Free part of filaments 2–3 mm and fused free part ± 1 mm, glabrous; anthers 3–4 mm long, spur ± 1 mm
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigma ± 1.5 mm long, dorsal lobe absent. Stigma with dorsal lobe, absent or much reduced (rarely welldeveloped), ventral lobe linear
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary with dense short stubby nonglandular hairs in apical 2/3, glabrous towards base Ovary with 6–8 ovules per locule.
Morphology Reproductive morphology Fruits
Capsule and seed not seen. Capsule 6–8-seeded, ellipsoid-obovoid, valves strongly sulcate; retinaculae strong, hooked
Ecology
Margins of wet montane forest; no altitude recorded
Morphology Reproductive morphology Flowers
Flowers in condensed racemiform to open panicles; bracts caducous or persistent; bracteoles 2, linear to narrowly ligulate, caducous or persistent
Morphology Reproductive morphology Flowers Corolla
Corolla glabrous on the outside, contorted in bud, subactinomorphic, basal cylindric part of tube usually very short, throat long and much expanded at the mouth, with illdefined herring-bones ventrally; lobes 5, two lateral in lower lip held horizontally to more or less vertically, similar to the two in upper lip, central in lower lip similar or longer and narrower, deflexed, with a papillate area above, throat with dense band of long stiff retrorse hairs on lower lip, this band becoming thinner on lateral and upper lip but often more or less continuous, also with longitudinal band from lower lip to base of tube
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 4, didynamous, inserted near base of throat, free part of filaments fused at base, below insertion forming two hairy ridges to base of tube; anthers 2-thecous, thecae oblong, glandular and often also hairy dorsally along connective, rounded at apex, outer theca of longer pair with long spur at base, other six thecae mucronate
Morphology Reproductive morphology Flowers Gynoecium Style
Style filiform, hairy but for apical few mm.
Morphology Reproductive morphology Seeds
Seed discoid, circular in outline, glabrous on faces, with dense hygroscopic hairs on rim
Note
About 15 species in tropical Africa and Madagascar. A very distinctive species known only from this one collection. It is clearly related to the M. alpinakilimandscharica complex. It differs most conspicuously in its very narrow sepals and small corolla with elliptic lobes.

Acanthaceae (part 2), Kaj Vollesen. Flora of Tropical East Africa. 2008

Morphology General Habit
Shrubby herbs; stems quadrangular; cystoliths conspicuous
Morphology Leaves
Leaves opposite
Morphology Reproductive morphology Flowers
Flowers in open much-branched panicles with long spreading branches; bracts leafy, persistent; bracteoles 2, linear to narrowly ligulate, caducous or persistent; pedicels straight or sharply bent or geniculate where attached to branch But the peculiar red flowers without long stiff hairs (obviously adapted to bird pollination) are strikingly different from anything seen in Mimulopsis
Morphology Reproductive morphology Flowers Calyx
Calyx 5-lobed, divided almost to the base into linear-lanceolate lobes, dorsal lobe longer than the rest but same width. Corolla straight or resupinate through backwards genuflexion of the pedicel, bright red to crimson or maroon, glabrous or puberulous on the outside, contorted in bud, subactinomorphic to distinctly 2-lipped, basal cylindric part of tube short or long, throat long, expanded at the mouth, with ill-defined herring-bones ventrally; lobes 5, the two in the upper lip and the two lateral in lower lip subequal, lateral in lower lip held vertically and together with two dorsal forming a “hood”, middle in lower lip spreading to deflexed, without a papillate area above, throat without ring of long stiff retrorse hairs. Stamens 4, didynamous, inserted near base of throat, held in the “hood” formed by the dorsal and lateral lobes; free part of filaments fused at base, below insertion forming two glabrous ridges to base of tube; anthers 2-thecous, thecae oblong, glabrous, rounded at apex, outer theca of longer pair with or without spur at base, other six thecae mucronate
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary with 6–8 ovules per locule.
Morphology Reproductive morphology Flowers Gynoecium Style
Style filiform, hairy but for apical few mm.
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigma with dorsal lobe absent, ventral lobe linear
Morphology Reproductive morphology Seeds
Seed discoid, circular in outline, glabrous on faces, with dense hygroscopic hairs on rim
Note
Epiclastopelma is closely related to Mimulopsis and might with some justification be considered congeneric 3 species in Tanzania.
Morphology Reproductive morphology Fruits
Also the fruit is constantly 4-seeded as opposed to 6–8-seeded in Mimulopsis. Capsule 4-seeded, ellipsoid-obovoid, valves strongly sulcate; retinaculae strong, hooked

Native to:

Burundi, Cameroon, Ethiopia, Guinea, Gulf of Guinea Is., Kenya, Liberia, Madagascar, Malawi, Mozambique, Nigeria, Rwanda, Sierra Leone, Sudan, Tanzania, Uganda, Zambia, Zaïre, Zimbabwe
