Floating leaves rather thick and leathery, narrowly oblong or usually narrowly 
oblong-lanceolate, 14 to 28 em. long and 5 to 10 cm. wide, not conspicuously narrowed 
at the apex, rounded; sinus 30 to 35 mm. deep, open, V-shaped; submersed leaves 
well developed, similar in outline to the floating ones but larger, sometimes 36 cm. 
long and only 7 cm. wide, very thin and delicate, crispate, glabrous 
like the floating ones; petioles slender, glabrous, cylindrical, 8 or 
9 mm. in diameter; rootstocks 20 to 25 mm. in diameter, densely 
leafy; leaf scars narrowly oval to semioval, 6 to 8 mm. long; 
flowers depressed-globose, 26 to 29 mm. in diameter and 19 to 22 
mm. high; sepals 6, glabrous, the outer ones 21 to 26 mm. long 
and 17 to 20 mm. wide, oblong, slightly narrowed towards the 
base, thin; the inner sepals of about the same length, orbicular, 
thin; stamens in 5 or 6 rows, the anthers scarcely if at all longer 
than the filaments; color of sepals canary yellow, tipped with 
green; petals and stamens yellow but paler than the sepals; fruit 
ovoid, 31 to 34: mm, high and 23 to 28 mm. in diameter, considera- 
bly constricted above, smooth or almost so below, conspicuously 
ribbed above; edges of the disk raised 4 or 5 mm., vertical or 
slightly spreading, orbicular in outline, almost or quite entire, 15 
to 17 mm. in diameter, its center depressed about 3 mm., smooth, 
3 to 6 mm. in diameter; stigma rays 10 to 14, linear, 4 mm. long, 
extending to within 2.5 mm. of the edge of the disk, distinct, with 
no trace of a median groove; color of fruit shining apple green, a 
little darker towards the top, occasionally darkening to oil green 
throughout; seeds ovoid, pointed but not sharply so, 4 to 5 mm. 
long and 3 mm. in diameter, the raphe rather obtuse and not con- 
spicuous. (PuLates 42, A, facing p. 96. 44, A, facing p.99.  Fia-

In Mohr’s Plant Life of Alabama this species is reported as 
occurring within that State. The specimens thus referred belong, for the greater part 
at least, to Nymphaea chartacea. In Gray’s Manual it is reported as occurring in 
southern Indianaand Illinois; but the ponds in which the plant grew are now drained, 
and we have been unable to procure fresh material from the region. It is exceedingly 
improbable that the species is found outside the States of North and South Carolina,
