Column short, straight, erect, much shorter than the corolla-lobes; anthers didymous, 4-celled and 4-lobed; lobes ultimately spreading; stigma placed between the anthers, 2-lobed, lobes spreading and deflexed. Ovary 2-celled or 1-celled by imperfection of the dissepiment; ovules numerous, attached to the centre of the dissepiment. Capsule coriaceous, indehiscent or tardily rupturing, more or less completely 2 - celled. Seeds numerous, obovoid; testa lax, cellular.
