NORTH AMERICAN NYMPHAEA. 93 
MILLER AND STANDLEY 
Mr. Andrew Allison, on June 28, 1904, collected in Lake Charles, Louisiana, mature 
fruit that undoubtedly belongs to this species; its description is as follows: 
Subglobose, abruptly constricted above, 35 to 40 mm. high and of the same diameter, 
smooth at the base, rather conspicuously ribbed above; edge of the disk 5 or 6 mm. 
high, diverging; disk usually 
oval, its center mostly umbo- 
nate, depressed 6 or 7 mm.; 
stigma rays linear, or widened 
at the base, usually slightly 
confluent at the base, with a 
distinct median groove; seeds 
about 4 mm, long and 3 mm. 
in diameter, the raphe only 
acutish and not conspicuous. 
Additional specimens examined: 
Dry— 
In bayou, Vermilion, Lafa- 
yette County, May 27, 1883, 
Langlois (Greene); near Lake 
Charles, July 10, 1893, Langlois 
(Greene); vicinity of Lake 
Charles, 1904, Andrew Allison 
219 and 323. 
The collector writes further: 
‘The plants can nearly always 
be found in the ponds or very 
slow-flowing streams of the pine 
barrens. The leaves are always 
floating on the surface with 
stems sometimes,a foot or two 
long. The plant can be found 
blooming from March to De- 
cember.”’ 
Not all the material from the vicinity of New Orleans belongs to this species, as 
noted elsewhere. 
In the National Herbarium there are two sheets of a Nymphaea collected at the 
south end of Long Pond, Lowndes County, Georgia, September 
4, 1902, Harper 1611. These specimens represent a plant 
resembling N. ludoviciana, and possibly identical with it. 
The leaves are floating, the sinuses closed, and their outlines 
similar to those of this species. Unfortunately Mr. Harper was 
unable to secure fresh material.
