Floating leaves oval to broadly oblong or suborbicular, thin, broadly rounded at the 
apex, 35 to 100 mm. long and 35 to 75 mm. wide, the sinus 15 to 35 mm. deep, two- 
thirds as long as the midrib or more; sinus narrowly tri- 
angular, or closed, the lobes just meeting, these triangular, 
acutish; veins rather inconspicuous, glabrous above, gen- 
erally somewhat pubescent beneath, especially when 
young; submersed leaves orbicular, very thin, somewhat 
crispate, of about the same size as the floating ones, their 
sinuses usually more open; peduncles and petioles terete, 
very slender; flowers depressed-obovoid, about 18 mm. in 
diameter and 12 mm. high when normally open, the 
perianth when spread measuring about 30 mm.; sepals 5, 
obovate or elliptical, about 10 mm. long and 6 to 8 mm.
