- The fruit is a subglobose five-Ioculed capsule, sometimes breaking up into pieces. Dehiscence loculicidal, dorsal sutures not thickened. The walls of segments are not clearly three-layered. The outer surface of the fruit is noticeably rugose and transversally wrinkled. Style one, short, straight, ascending inside crater- like depression in the apex of capsule. The fruit peduncle is very short. Calyx persistent with five lobes longer than half the length of capsule. Joint between calyx and pedicel distinct. There are many crescents or half-moon-shaped seeds in each locule. Their surface knobby-reticulate. The seeds laterally f1attened with straight or concave ventral margins and semi-circular dorsal margins. Outline of the seed on the distal regions is acuminate and somewhat bent. Seed axial placentation in medial and upper part of the filamentous bundle of conducting tissues running from pedicel to style.
