    Flora Zambesiaca Acanthaceae (part 2) by Iain Darbyshire, Kaj Vollesen and Ensermu Kelbessa

    Annual or perennial herbs or subshrubs; cystoliths present; stems sub-angular, sulcate or ridged.
    Leaves opposite-decussate, petiolate, pairs equal or anisophyllous, usually evergreen.
    Inflorescences axillary and/or terminal, comprising a series of monochasial cymules, arrangement of cymules variously fasciculate, umbellate, spiciform, strobiliform or cylindrical, sometimes compounded into verticillate or paniculate thyrses; main axis bracts paired, equal to highly unequal, free or basally fused, sometimes foliaceous; cymule bracts paired, equal to unequal, free or fused for up to – their length; bracteoles paired, equal to ± unequal, free, narrower than cymule bracts.
    Calyx divided almost to base or with a distinct tube, 4- or 5-lobed, lobes subequal to ± unequal in length, often hyaline.
    Flowers protandrous.
    Corolla bilabiate, variously white, pink or purple, usually with darker guidelines; limb resupinate, tube twisted through 180°, cylindrical below twist, weakly to strongly expanded from above twist to mouth; lip held in upper position recurved distally, 3-lobed or with only median lobe well-developed, palate longer than lobes; lip held in lower position unlobed, apex acute, obtuse or shallowly emarginate, recurved distally.
    Stamens 2; filaments attached at corolla mouth, exserted, initially straight, becoming divergently reflexed and bending out of corolla in female phase; anthers monothecous, thecae ellipsoid; staminodes absent.
    Disk cupular with V-shaped slit, 2-awned.
    Ovary oblong-ovoid, glabrous, bilocular, 2 ovules per locule; style filiform; stigma bifid, exserted from corolla tube, held below anthers.
    Capsule clavate, shortly stipitate, placental base inelastic.
    Seeds held on retinacula, lenticular or compressed-ellipsoid, with a hilar excavation, smooth or tuberculate.
    Genus confined to the Old World tropics and subtropics from Africa to Australia, with the highest diversity on Madagascar where a revision is sorely needed.
