BARNHART: A NEW UTRICULARIA 581 
the calyx, while those of U. juncea are conspicuous. U. juncea 
is a species of distinctly southern range, and has not been hitherto 
reported as occurring on Long Island, as far as I am aware. It 
was found by me, however, in September of the present year 
(1907), near Riverhead, in a pond adjoining that from which U. vir- 
gatula was first taken. Its occurrence on Long Island is not at 
all remarkable, but it is surprising that it has so long escaped 
detection. 
Closer still is the relationship of U. virgatula to the U. simplex 
of Charles Wright, first described from Cuba, and since reported 
from Florida. The resemblance is indeed so close that I am unable 
to name any character by which they may be distinguished. How- 
ever, the name U. simplex has been in use for nearly a hundred 
years for an entirely different Australian species (U. sémplex R. Br.), 
So that Wright’s species is without any tenable name; instead of 
renaming it, it seems better to refer the material from Cuba and 
Florida provisionally to U. virgatula. If future comparisons should 
prove that the southern material is distinct, it will then be necessary 
to assign it a new name. 
It might seem unreasonable to suggest that a gamopetalous 
Spermatophyte found in Florida could be conspecific with one 
found in New Jersey, no intermediate stations being known ; yet 
as a parallel case may be cited another species of the same genus. 
U. resupinata B. D. Greene was discovered about seventy-five 
years ago in eastern Massachusetts ; one by one other localities 
came to light, until now it has been found in every one of the New 
England States, New York, New Jersey, Pennsylvania, Michigan, 
and Indiana. The same species, or one so closely resembling it 
that no one has yet distinguished it, is now known to be fairly 
common in Florida, and has been collected in southern Georgia ; 
but no stations are known intermediate between these extreme 
southern ones and those in New Jersey, Pennsylvania, and Indiana.
