124 PITTONIA. 
15. V.rnprvisa, Greene,n.sp. In maturity 6 to 10 inches 
high, very erect both as to leaves and peduncles of apetal- 
ous flowers, these in fruit of scarcely one-third the length 
of the petioles: leaves all undivided and of a peculiar out- 
line between deltoid and transversely rhomboid, the largest 
34 inches broad, the length usually less, some cuneately ta- 
pering to the petiole, others almost truncate at base, all 
deeply toothed or cleft into subfalcate lobes or rounded teeth, 
the lobes themselves when deep and broad crenate-toothed 
on one margin, both faces glabrous except as to a few short 
and obscure hairs along the nerves and margin, the petioles 
and peduncles both slender and wholly glabrous: sepals in 
petaliferous flowers lanceolate, 3-nerved, strongly and trun- 
cately auricled, glabrous even marginally: capsules from 
apetalous flowers oblong, their sepals small, with long auri- 
cles. 
This most remarkable violet, with rank flabelliform and 
faleate-toothed foliage, first became known to me in the 
summer of the year 1898, as I was botanizing on the prairies 
of southwestern Minnesota. Its aspect is so very strang® 
the pattern of its rank foliage so peculiar, that had it come 
to me first from some correspondent, and in herbarium 
specimens, I think I might have been long in guessing 
rightly its affinities. But, in the field, its habitat was that 
of V. pedatifida; that is to say, it grew in such soil as in 
which one expects to find that species, in the prairie regions, 
and not only so; where this plant was abundant, on the out- 
skirts of the field which it occupied I found a few specimens 
- of real V. pedatifida, though with scarcely a hint of inter- 
gradation between the two. With this knowledge of the 
plant I labeled my specimens V. pedatifida, var. indivisa at 
the time. 
It was after having seen these specimens of mine, and 
heard my statement of the plant’s affinities, that Mr. Pollard
