Fruits elliptic, obovate, or orbicular, flattened or slightly twisted; valves thickened, veins often prominent, glabrous or uniformly pubescent, trichomes subsessile or short-stalked, cruciform and 3-rayed, sometimes mixed with stouter, simple or forked, subsetiform ones to 0.6 mm, not hooked; septum complete, (membranous); ovules 6–12 per ovary; style 0.1–0.2 mm.
