the appearance of having been carefully drawn), it does not repre- 
sent any species at present known, but it would be rash to deny 
that such a plant exists, until the Southern States have been 
better explored than they are at present. Delessert says of his 
plant “ Crescit in Carolina (Fraser),” and it should be borne in 
mind that Fraser was acquainted with Walter, and is said to have 
attended to the publication of his “‘ Flora Caroliniana’’ in London, 
so that he was in an excellent position to know Walter’s species. 
DeCandolle says of Nymphaea reniformis, ‘‘(v. s.),’’ doubtless re- 
ferring to one of Fraser’s specimens, probably the same one from 
which Delessert’s figure was drawn. So unless there is evidence 
to the contrary this figure must be accepted as representing Wal- 
ter’s Nymphaea remformis, a species which should perhaps take 
rank with Gordonia pubescens and Pyrola oxypetala as being lost 
to science. 
In later years VV. reniformis has been associated in synonymy 
with JV. tuderosa Paine,* a northern species, but probably on insuf- 
ficient grounds. About ten years ago Professors Trelease and 
Hitchcock independently transferred DeCandolle’s Nymphaea rent- 
formis to Castalia, apparently overlooking the fact that Walter 
was the author of the species. Professor Hitchcock’s plant (from 
Towa) is C. tuberosa, and the identity of that of Professor Trelease 
is immaterial, as he gave neither description nor synonymy. A 
few years later Mr. Nash + published the same combination, credit- 
ing the specific name correctly to Walter, but associating it with 
specimens collected by him in Lake Ella, Lake County, Florida, 
in 1894 (nos. 1153, 1180).
