New England has been found only in northwestern Connecticut. 
Mr. E. E. Brewster found it in a swampy meadow at 1100 feet eleva- 
tion in Cornwall in 1879, and it also occurs in a swampy wood-margin 
in Canaan. Both of the foregoing are species of the northeastern 
Mississippi basin east of the prairie and the adjacent Alleghenian 
region, and just reach western New England. They are not, perhaps, 
strictly calciphiles but our stations for them are in more or less cal- 
careous districts. 
Ranunculus longirostris is rare in Vermont and local at Salisbury, 
Conn. Its New England range is thus similar to that of the two 
preceding species, but according to the manuals, its general range is 
much more extended. 
Ranunculus delphinifolius is a water plant with scattered stations, 
not reported from the northern half of Maine and New Hampshire, 
southern Vermont and Cape Cod. More reports are needed for con- 
clusions. ' 
R. Purshii was discovered by Prof. M. L. Fernald at New Limerick, 
Aroostook county, Me., and later at Phair in the same region by C. H. 
Bissell and R. W. Woodward. These are evidently southern limits 
of a circumpolar species. R. reptans, var. ovalis is more southerly 
than the species in its range, but not enough specimens are available 
for generalization. 
Thalictrum dasycarpum is known only in southeastern Connecticut 
at Franklin (R. W. Woodward) and at Groton (C. B. Graves). The 
specimen from Milton, Mass., quoted in RHopora xviii. 168, 1916 
was incorrectly determined.

CARDAMINE OLIGOSPERMA AND ITS NEAR ALLIES.

WILHELM SUKSDORF. 
In Mr. G. S. Torrey’s article “The Varieties of Cardamine oligo- 
sperma” (RHopora 17 p. 156, 1915) my notes on C. oligosperma and 
related forms were quoted. Since that time I have been able to make 
some further examinations and still believe that these forms should
