THE GENUS VIOLA IN MINNESOTA. 131 
this a sheet of fine fruiting specimens. V. subvestita is 
therefore a violet of the northeastern and wooded section of 
the State,and need not be expected southward or westward. 
25. V. CARDAMINEFOLIA, Greene, Pitt. iv. 289. Founded 
by me quite recently on a plant from Quebec, it is most 
interesting to find this inhabiting the northeastern moist 
wooded section of Minnesota, adjacent to Lake Superior. 
Two excellent sheets by E. P. Sheldon are in the Herbarium, 
the one from near Brainerd, the other from Nichols, both in 
the Mille Lac district, collected in 1892, and labeled 
“V. longipes, Nutt.” Again, last year, it was obtained at 
Lake Itasca by Lyon and Rosendahl. It is a beautiful 
species, perfectly distinct from V. Labradorica on the one 
hand and V. sudvestita on the other, and of more restricted 
range than either. 
26. V. pupEscens, Ait. Kew. iii. 290. The species seems 
to prevail throughout western Minnesota, both north and 
south, as evinced by a considerable parcel of specimens, while 
of the analogous V. scabriuscula I find no trace in the collec- 
tion. Some of the more imperfect specimens are to me 
ambiguous between this species and the next. 
27. V. acHLYDOPHYLLA, Greene, Pitt. v. 87. Although 
the collection contains a half dozen sheets which I readily 
refer to this new segregate, the best specimens of all are those 
constituting the type material and collected by myself, 
although they were in apetalous flower and fruit only. The 
sheets of it in the Minnesota collection are two obtained 
in 1892 by W. D. Frost, one from Acton, the other from 
Lichfield, and neither of these was referred to V. pubescens, 
but both to V. Canadensis! This, it seems to me, must sig- 
nify that the flowers are scarcely yellow, but perhaps almost
