Characteristics

Plants small with the basal rosulate leaves inserted close together on a very short ascending stem, giving it a straggling appearance. Roots several, fairly thin and long. Leaves apetiolate, stipules fused to the lamina at the base, free part entire below, fimbriate above, ferruginous, 2 mm long; lamina cuneate to spathulate, rounded at the apex, tapered and slightly hairy towards the base, up to about 2 cm long and 5 mm broad above, bearing both types of tentacles, texture usually soft and thin. Inflorescence borne on a wiry scape, elongating during anthesis, up to 25 cm long, the base straight or somewhat curved, glabrous or with a few straggling hairs below; pedicels up to 5 mm long; flowers small, up to about 10, secund, rarely open. Calyx-lobes ovate, 3 mm long. Petals white, pink or purple, 5 mm long. Stamens with the upper part of the filament and connective dilated. Styles forked from the base and divided again towards the apex, the stigmatic apex somewhat distended. Capsule oblong; seeds fusiform, the testa extended on both sides. Flowering during the summer months.
