Fruits ascending to spreading, narrowly linear, straight or only slightly curved inward, not torulose, 2-5(-7) cm × 2-3 mm, angustiseptate, not striped; valves with prominent midvein, pubescent outside, trichomes 2-4-rayed, glabrous inside; ovules 36-50 per ovary; style cylindrical or slightly flattened, stout, 1-4 mm, sparsely pubescent; stigma slightly 2-lobed, lobes as long as wide.
