As long ago as in 1886 Dudley (Cayuga Flora, p. 34) called atten- 
tion to this plant, listing it as “ A. canadensis, Torr. and Gray; (form). 
(In sphagnum marshes, and agreeing with var. oligocarpa in charac- 
ter of the leaf and length of petals, but racemes usually have 4-6 
flowers.) Round Marshes. South Hill Marsh." In the first of — 
the above cited papers in Ruopora (p. 135 and 149) the writer again 
called attention to it, noting its affinity with A. oblongifolia. Since 
that time the plant has continued to give trouble in Central New 
York, where it is abundantly distinct from any local species; yet in 
all this time it has not been reported from outside the New York 
region. Species with a limited range of this sort occur very excep-
