Calyx 4-5 mm, glabrous or with some thickish crisped hairs at the lobes, the latter ovate, subacute, +-spreading at anthesis, 2-3 mm, laxly and longish caducously glandular-fimbriate, short-pubescent at the very apex. Corolla cylindric-urceolate, 6-7 by c. 2 mm, contracted both at the base and the mouth, glabrous, or initially with some scattered, appressed, glandular hairs in its upper part, white, lobes 4 or 5, c. 1.5 mm.
