90 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
to 38 mm. in diameter, about 22 mm. high; sepals 6, glabrous; the outer ones obovate, 
rounded, somewhat narrowed at the base, about 32 mm. long and 20 mm. wide; inner 
sepals thinner, deltoid-obovate, retuse; petals broadly cuneate, 10 mm. long, truncate 
or retuse; stamens in 6 rows, their anthers almost twice as long as the filaments; color 
of sepals as in N. advena; disk when young of the same color as the sepals; stamens 
lemon yellow; petals a slightly lighter yellow throughout; fruit narrowly ovoid, 35 
mm. high and 25 mm. in diameter in the largest specimens, only slightly constricted 
above, coarsely ribbed above but almost smooth at the base; stigmatic disk orbicular, 
20 mm. in diameter, depressed about 4 mm. in the center, its edge entire or slightly 
undulate; stigma rays linear, distinct, unequal, with slight traces of a median groove, 
6 mm. long, extending to within 2 mm. of the edge of the disk, 10 to 15 in number, 
usually 12 or 14; body of fruit apple green, the disk chrome yellow. (Puare 36, F, 
facing p, 73. Fiaures 16, a, 17.)

Dr. J. K. Small in the original description of this plant compares it with so-called 
Nymphaea advena, pointing out numerous differences. The plant with which it was 
compared was not advena but the northern Nymphaea americana. In the herbarium 
of the New York Botanical Garden at that time there were practically no specimens 
of N. advena, nearly all of those so labeled being americana. Evidently the Florida 
plant is amply distinct from the latter. The description of Nymphaea advena in Doctor 
Small’s Flora of the Southeastern United States applies to N. americana and the key 
separates americana (under the name advena) from advena (under the name macrophylla). 
It can readily be seen by examination of the key that the characters used for separat- 
ing the two species will not hold for separating true advena from the Florida plant. 
The material at our command, and it seems to be ample, does not warrant us in main- 
taining macrophylla as a separate species. The only difference that we can see lies in 
the larger size of the Florida plant and the longer, more acute, thicker leaves whose 
lobes are rather narrower.! 
It is not certain whether the Cuban specimens belong here. The leaf outline seems 
tobe thesame. Fresh material collected in 1910 in the vicinity of Havana by Brother 
Leén shows that the outer edge of the stigmatic disk is tinged with a dull purplish red. 
This color does not extend to the interior of the crater and is very different from the 
bright geranium red of the following subspecies. 
1 Under the provisions of the American Code we would be justified in substituting a new name for the 
somewhat inappropriate macrophylia.—G. 8. M.
