 The large (5-5½ × 2-2½ cm), more or less pendulant, star-symmetrical, hermaphrodite flowers stand individually in the axil of the leaves on a short flower stem.The calyx consists of eight to ten, free, concave, and spirally arranged sepals which gradually increase in size from outer to inner, overlap in the bud, and do not fall after flowering.These sepals are approximately oval in shape, leathery in consistency and are covered in simple one-celled straight or slightly curved hairs of 0.2-0.6 mm.
