height of the foliage. The capsules of these are about three- 
fourths of an inch long in the longest. The real V. Bernardi 
is, then, a strongly characterized mutate. 
The plant I had from Rock Co., Wis., from Mr. Bernard 
Saunders in 1897, is intermediate between V. Bernardi and the 
parent species. 
V. PERPENSA. Tall and slender, even at petaliferous flower- 
ing 8 or 9 inches high and with peduncles and petioles of equal 
length, all slender, glabrous or nearly so: leaves small in pro- 
portion, thinnish, broadly subcordate in outline, deeply cleft, 
or the small earliest only subserrate-toothed or lobed, the seg- 
ments of all the later regular and even, a little falcate, the lower 
margin of each apt to be serrate-toothed ; largest summer foliage 
3 inches wide near the base, the length a trifle less, all the veins 
and even now and then the leaf-surface strigulose-hirtellous, 
most so beneath, sepals oblong-lanceolate, acutish, very lightly 
and delicately ciliolate : apetalous summer flowers on short very 
slender prostrate and even sometimes hypogeous peduncles: 
petaliferous flowers often fertile, their oblong capsules middle- 
sized. 
The type specimens as to early state are on U. S. Herb. sheet 
441,069, and were collected on a moist prairie at Dunning, near 
Chicago, Ill., 18 May, 1902, by Dr. H. S. Pepoon. There is 
_ another from Ottawa, Ill., by C. F. Johnson, May, 1889, and a 
third from “ Low prairies, Dupage Co.,” Ill, by Dr. W. S. Mof- 
fatt; all these from the same region roundabout Chicago. But 
the plant was first known to me as seen and collected by myself at 
Dixon, UL. from a low prairie, 18 June, 1898. I incautionsly label- 
led the specimens V. Bernardi, not so much overlooking the almost 
or quite hypogeous nature of their summer flowers as suspecting 
that this might prove to be a character of that plant, the sum- 
mer flowers of which were not then known. It was from a view 
of these specimens of mine, labelled wrongly V. Bernardi, that 
the character of the summer peduncles was taken by Mr. Pollard 
for his account of V. Bernardi in Britton’s Manual. 
I doubt that V. perpensa has any intimate relation to V. 
pedatifida ; but I find it convenient to name and define it here, 
as having been mistaken for that evident mutation, V. Bernardi.
