Calyx tube shorter than  calyx lobes, with calycine colleters. Corollas pale lilac, funnelshaped; corolla tube is longer than corolla lobes. Short-styled flowers with long filaments and free, sagittate anthers without sterile, apical appendages. Long-styled flowers with short filaments and connate, non-sagittate anthers with sterile, apical appendages. Anthers basifixed. Filaments often hairy. Stamens inserted in lower part of the corolla tube. Pollen released as monads (single pollen grains). Ovary unilocular, ovoid, with parietal placentas, tapers into the distinct style.
