Calyx deeply 5-lobed; lobes narrow, equal, apex acute. Corolla pink, resupinate 180° by torsion of tube; tube slender, widened apically, limb 2-lipped; lower lip (in upper position) 3-lobed, lobes ascending cochlear in bud; upper lip (in lower position) entire or emarginate. Stamens 2, exserted from mouth of corolla; anthers 2-thecous; thecae unequally inserted to superposed, base muticous; staminodes absent. Stigma 2-cleft. Capsule substipitate or stipitate, 2-4-seeded; retinacula present; placenta with retinacula separating elastically and rising from inner capsule wall at dehiscence.
