Calyx 10–15 mm long in flower, inflated in fruit; sepals unequal, ovate, about 8 mm long, concave, softly pubescent, with 6–7 purple-brown nerves deeply sulcate-plicate and with small purplish spots, hairy on the nerves. Corolla widely funnel-shaped, 15–20 mm long, yellow or whitish with a purplish centre, shallowly 5-lobed to pentagonal, hairless or thinly pubescent towards the base.
