underneath, round-reniform to cordate, lightly and often ob- — 
scurely crenate, obtuse, ł to 14 inches in diameter, all but the — 
earliest distinctly cucullate: peduncles minutely and subulately — 
bibracteolate above the middle, sepals lanceolate, or the two 
broad ones lance-oblong, rather short, auricles very prominent, 
margins partly naked and partly bristly-ciliate: corollas of 
middle size, scarcely ł inch broad, deep-blue rather than violet, 
upper petals largest, all very broad and rounded, the laterals 7 
bearded with very short hairs strongly clavate from a slender 
ase, 
Type collected by myself in an open and sunny but very wet ; 
meadow of sedges, near Jackson, Michigan, 17 May, 1902. 
This is genuinely a bog-meadow violet, and more truly allied 
to V. cucullata than some others. On proceeding down a hill- 
side to the low meadow where I found it, I first encountered, on 4 
the highest border of the wet land, a diminutive blue violet — 
which, although I had not before seen it growing, I immediately 
suspected would prove to be my V, crenulata ; and passing t0 
lower land more distinctly boggy, I left that behind. V. crassula 
had its own area, with no congeneric associate. Its size, fleshi- 
ness and stoutness, as also the leaf-outline suggested V. vagula, 
which also I had never seen growing; but it proves, to my re- 
gret, wholly irreconcilable with that, and I am compelled to 
recognize it as another proper species of the same group. 
Six years ago I had the good fortune, after a single season's 
study of certain acaulescent violets of the East, to be able to- 
indicate, among other facts relating to the group, the strong and 
plain distinctions between the common upland plant with un- 
cut cucullate foliage, and the analogous one inhabiting bog- 
meadows exclusively.’ While I felt a doubt, and openly ex 
pressed it, as to the correctness of every application of the names — 
V. obliqua, Hill, and V. cucullata, Ait., as to the perfect distinct- 
ness of the species, there was no room in my mind for ‘doubt ; 3
