Small herbs with tufted rosettes bearing 1-2 fairly long, slightly swollen roots. Leaves apetiolate; stipules represented by 2 minute filaments, one on each side of the margin at the base, deciduous; lamina obcuneate, c. 1 cm long and 5 mm broad, tapered below, truncate at the apex, the marginal apical tentacles with flattened glands much larger than the discal tentacles, lower surface glabrous or glabrescent, 3-nerved. Inflorescence central, scape erect, 5-10 cm long, occasionally somewhat longer, with usually 2-3(1-10) flowers fairly close together; pedicels 2-8 mm long. Calyx-lobes 5 mm long. Petals white or rarely violet, broadly obovate-cuneate, c. 8 mm long, when faded forming a subulate body just exserted from the globose calyx. Stamens on slender filaments with the connective dilated. Styles 3, divided from the base, patent-erect, stigmas capillaceo-multifid. Capsule oblong; seeds ovoid, 0.3 mm, punctulate, blackish brown.
