    Erect herbs or shrubs to 3 m tall, often glandular or viscid pubescent, unarmed. Leaves entire, sessile or petiolate, sometimes large; minor leaves often present as auricles or cauline stipule-like processes. Inflorescence a terminal, many flowered panicle, bracteate, and the pedicels bracteolate, articulating at the base. Flowers regular or somewhat zygomorphic, 5-merous; calyx campanu- late, somewhat accrescent but not enclosing the fruit; mostly 5-lobed, the lobes short or elongate, persistent; corolla tubular, salverform or elongate, campanu- late, variously colored, prefloration contorted-plicate, rarely imbricate; stamens 5, equal or not, filaments equally or unequally inserted at various levels in the corolla tube, often pubescent, sometimes geniculate, anthers included or nearly so, dehiscent longitudinally, 2-thecate, the connective apparent or not; ovary 2-loculed on an annular hypogenous, sometimes nectiferous disc, the placentae axillary, somewhat proliferated, ovules numerous, anatropous, stigma included or exserted. Fruit a chartaceous or coriaceous capsule, dehiscent apically by septicidal and locucidal slits; seeds many, minute, globose or often prismatic, the embryo small, straight, curved, bent or arched. Chromosomes mostly n-12 or 24.

  • Morphology

    Fruit capsular, membranous to slightly woody, 2(or rarely 4)-locular, retaining the loose placentas, apically dehiscent by 2 rather long, septicidal slits, the 2 dry valves often 2-fid (or sometimes the capsule 4–many-valved).
