In a swamp at Franklin, Southampton county. Collected 
June 17th, nearly all the specimens being in fruit. Its range, 
as given, has been “S. Carolina near the coast to Texas.” As 
‘shown by examination of the Boston Journal of Natural History, 
in which the Plante Lindheimeriane is published, Déanthera 
humils, Engelm. and Gray, is a xomen nudum, this being all that 
‘is said: «159. Dianthera humilis. In clear water. June.”

_ Hydrolea Caroliniana Michx. F1. Bor. Am. 1: 177 (1803). 
Collected in wet ground on the southern boundary of Virginia 
(Southampton county), near Margarettsville, N. C., on the north- 
ern border of its range, which is given as “N. Carolina to 
So. Florida and Louisiana?’ Kuntze, in his Revisio Generum 
Plantarum, cites both guadrivalvis and Caroliniana as distinct spe- 
cies, whereas we have considered them names for the same plant. 
‘Michaux in his Flora cites Hydrolea quadrivalvis, Walt., as a_ 
synonym of his H. Caroliniana. If they are two distinct species 
we do not seem to have the material in this country to substan- 
tiate it.
