Floating form: stipe up to 26 cm long, slender, hairless. Leaflets up to 15-28 × 10-29 mm, broadly obovate, outer margin rounded, entire to shallowly irregular, hairless, brownish suberous streaks between the veins of the lower surface. Dry land form: stipe up to 13 (15) cm long. Leaflets up to 6-13 × 4-10 mm, obovate, outer margins subentire to shallowly incised, slightly hairy.
