THE GENUS VIOLA IN MINNESOTA. 125 
gave out in Britton’s Manual, concerning V. pedatifida, that: 
“Forms occur, in which the leaves are merely slightly lobed.” 
The Minnesota University Herbarium gives evidence that 
V. indivisa was collected as early as the year 1892, at Oshawa, 
by Mr. Ballard, who labeled his plant V. palmata, just as he 
had done in the case of V. Bernardi; though these two plants 
are,as shall presently indicate very different, the one from the 
other. Again, in 1902, Mr. C. O. Rosendahl obtained fine 
specimens, also in the summer state only, at Spring Grove, in 
southeastern Minnesota. These specimens, as preserved in 
the University Herbarium where Mr. Rosendahl isa student, 
are exceedingly fine, the leaves being of an elegant cut, 
somewhat different from those of my type (see plate XIII). 
They are more evenly, rather more deeply and falcately cut ; 
and the pubescence of the veinlets and margin are in these 
not obscure. Otherwise they are quite like mine. I regret 
that we do not yet well know the early petaliferous-flowering 
condition of the plant. The sheet collected by Mr. Ballard, 
is of the plant in its æstival stage (July), but with some ab- 
normally late petaliferous flowers; and it is from these that 
I have drawn the description of the sepals. I trust it may 
hold for those of the early and normal flowers, when this 
plant shall have been detected in its normal stage. 
I take this strangely marked violet to be either a recently 
produced specific offshoot from V. pedatifida, or else the sur- 
vival of an ancient type of which V. pedatifida may be the 
more vigorous and the now prevailing descendant. I also 
regard V. Bernardi as in the same category; though that, but 
for its greater fleshiness of texture, and the pronounced hairi- 
ness of its stout petioles, might be viewed as nearer V. peda- 
tifida than is the present plant. But V. indivisa notwith- 
standing its remarkable foliage, is of the thin texture and 
almost complete smoothness of V. pedatifida. 
The drawing of the corollas of V. indivisa was made from
