THE GENUS VIOLA IN MINNESOTA. 123 
only other sheet in the collection is from Tower, June, 1893, 
by E. P. Sheldon, these specimens being in full petaliferous 
flower. Both stations are in the Lake Superior region, and 
the species will hardly be found elsewhere in the State. 
13. V. pepatiripA, Don. Gen. Syst. i. 320. Some six- 
teen sheets of this, now in the Herbarium, show the species 
to be distributed throughout the southern and western or 
prairie sections of the State; sometimes occurring in sandy 
soil among the hills, but as often in the open prairie in the 
richest of prairie soil. It is common from [Illinois and 
Missouri northward into Manitoba. 
14. V. BERNARDI, Greene, Pitt. iii. 260; Pollard, in 
Britt. Man. 635. This not altogether satisfactory species. 
holds its characters well enough in Minnesota. There are. 
six sheets of it in the Herbarium; and such of them as 
` Were in hand when the Metasperme was written were all 
referred, not to V. pedatifida (or V. delphinifolia) to which it. 
is so nearly allied, but to V. palmata. All the old labels 
ear that name, except one in which the species was referred 
to V. pedata. This fact is not insignificant, indicating, as 
it does so plainly, that the idea of its being a form of V. 
pedatifida is not suggested to the field observer. Its pecu- 
liarities as a subspecies near to V. pedatifida are, a lower and 
More robust habit; merely palmatifid somewhat fleshy- 
herbaceous foliage, on very pronouncedly hairy petioles; 
broader, more obtuse and more notably ciliate sepals, and 
broader petals. No specimens, however, of quite such pro- 
nounced characters as the originals from Rock Co., Wis- 
consin, are in the Minnesota collections. It is hoped that 
future field work in Minnesota may result in a more thorough 
knowledge of this interesting plant, which I regard as of 
perhaps recent descent from V. pedatifida.
