MILLER AND STANDLEY—NORTH AMERICAN NYMPHAEA. 95 
DESCRIPTION. 
Petioles and peduncles slender, glabrous; floating leaves glabrous, thin, ovate, 14 
to 23 cm. long and 8 to 14 cm. wide, conspicuously narrowed at the apex, broadest at 
or just above the base; sinuses 3.5 to 6 cm. long, very narrow or closed, the lobes some- 
what unequally rounded; submersed leaves similar in outline, 15 to 23 cm. long, 
rounded at the apex, crisped, very thin and delicate; flowers 30 to 35 mm. in diameter; 
sepals 6, 12 to 20 mm. long, oblong, obtuse; fruit not seen. (Ficures 13, ¢, 23.) 
In Mohr’s Plant Life of Alabama this is listed as Nymphaea sagittifolia. The distri- 
bution of this species in Alabama is given as the 
“Central Pine belt to Coast plain. Still-flowing water. 
Most frequent in the coast region. Tuscaloosa County 
(E. A. Smith). Montgomery, Mobile, and Baldwin 
Counties. Flowers lemon yellow. June, July; not 
rare.”’ Just how many of the plants thus listed belong 
to our new species it isimpossible to tell. Probably 
most of them belong here. At any rate, none of the 
plants thus referred to are N. sagittifolia. We are re- 
luctant to describe a Nymphaea from dried material, 
but in this case there can be no doubt about the dis- 
tinctness of the plant. The leaves, while resembling 
those of N. ulvacea and N. sagittifolia in texture, are 
very different in outline. From our studies in this 
genus we may confidently expect that when fresh ma- 
terial of this plant is secured it will present other 
marks of distinction. 
We have seen the following additional dried mate- 
rial that seems to belong here. The leaves of the 
Florida specimens are somewhat more obtuse than those 
from farther west, but they are equally thin; the flowers have the very thin sepals 
so characteristic of this and Nymphaea fluviatilis.
