from oblong to linear-lanceolate, often quite entire, the clefts 
often not extending so far as to the middle of the leaf, the 
petioles very notably pubescent, as also even the leaf margin. 
The plant is known to me only as inhabiting the prairie 
regions of southern Wisconsin, in Rock and Dane counties; 
and it has always been taken for V. palmata by the students 
of Wisconsin botany, where true V. palmata does not occur. 
V. ranunculifolia of Jussieu might possibly be the same as 
the present plant, though that is described as glabrous; but 
it was founded on a specimen obtained by Michaux, whose 
travels did not extend so far north in the Mississippi Valley 
as the known habitat of V. Bernardi. I dedicate the plant 
as à variety or subspecies to Mr. Arthur Bernard Saunders, 
who has done me much service in furnishing both living and 
dried plants of the violets of Rock County, Wisconsin, a 
region with whose flora I had a better field knowledge forty 
years since than now. 
Dr. Britton about a year ago was of the opinion that the 
plant was a distinct and undescribed species; but he has 
since receded from that view. 
PRIMULA Macouxri, Greene, p. 251, supra. Since the pub- 
lieation of this fine Northwest American insular species, for- 
merly mistaken for P. nivalis, Mr. Theodor Holm has kindly 
procured for me, through some European correspondents of 
his, authentic P. nivalis from Siberia; and the points of dif- 
ference between the two are more numerous than I had made 
out from descriptions and the original figure of P. nivalis. 
The foliage in this last is of much thinner texture, much 
more. conspicuously veiny, even reticulately venulose, the 
reticulations showing central glandular dots. The dried 
leaf is so thin as to be perfectly translucent, and its margin 
is finely dentate, as Pallas’ figure shows. But in P. Macount 
the leaves are thick, completely opaque when dry, scarcely 
veiny, not in the least reticulate or dotted; nor is there any 
trace of farinose indument, The species is, then, not at all
