The flowers are set on short pedicels (i.e. flower stalks). An epicalyx is present, which is a series of subtending bracts that resemble sepals. It has large, ovate segments that are dentate (i.e. toothed along the margins), though sometimes only very slightly so. They are cordate (i.e. heart-shaped) at the base and acute at the apex. The true calyx is small, measuring only about 5 mm in length. Its shape is cupular, and there are 5 subtle dentations present. The corolla is a pale yellow on colour, sometimes with a purple centre, and occasionally entirely purple. It measures 3 to 4 cm in length. The staminal tube bears the anthers and is 1.5 to 2 cm in length. The fruit is a 3 to 4 celled capsule measuring 1.5 to 2.5 cm across. It is ovoid or oblong in shape and glabrous (i.e. hairless). The surface is pitted and a beak is present at the termnial end. The seeds within are globular and are covered in long white cotton.
