Description

Perennial herbs or shrubs. Stems erect, procumbent or clambering, pubescent or occasionally glabrous. Leaves petiolate, opposite pair connected by transverse ridge; blades narrowly lanceolate to ovate, margin entire or somewhat dentate. Inflorescences terminal or axillary racemes, these lax or dense, often secund, flowers single or paired, pedicels short; bracts 2, small, linear to narrowly deltoid; bracteoles 2, similar to bracts. Calyx 5-lobed, lobes linear-setaceous or lanceolate, subequal; corolla more or less regular, infundibuliform, limb 5-lobed, purplish, blue, yellow, or white, tube short to long, funnelform, ventricose or narrow, throat ampliate or campanulate, lobes 5, equal, spreading, imbricate in bud, abaxial lobe with a palate in form of longitudinal fold; stamens 4, inserted in pairs in widened part of corolla tube, included, didynamous, or occasionally posterior ones reduced to filiform staminodia, anthers 2-thecous, thecae parallel, inserted equally, approximate, minutely spurred or muticous at base; disk cupulate or annular; ovary with 2 ovules per locule, style long, subulate, stigma thickened, obtuse or minutely 2-lobed or subcapitate. Capsules stipitate, pubescent, elliptic, base contracted and solid, lacking seeds, retinacula present, septae with retinacula remaining attached to inner wall of mature capsule; seeds 2 or 4, ovate or compressed orbicular, irregularly angular, rugose or tuberculate.
