FOUR NEW VIOLETS. 65 
of the plant in full vernal flower were sent me this season, 
from the same spot, by my niece, Miss Nellie C. Greene, so 
that I have now all needful data from which to determine 
itsrank. Of its distribution I know little; but it may safely 
be inferred that it is common iu low prairies of at least 
southern Minnesota, northern Iowa, and parts adjacent. 
Itis to be observed that in V. pratincola, as in perhaps 
not a few of the more northerly acaulescent violets, capsules 
and seeds are produced freely from the early and petaliferous 
flowers, these, of course, being borne on peduncles that are 
erect in maturity as at flowering time; but still, the greater 
proportion of seeds is produced from the later more or less 
subterranean and horizontal peduncles. 
V. Dicxsontr. Allied to V. cuspidata, but the herbage 
light-green, the pubescence more sparse and hispidulous, the 
petaliferous flowers on nearly terete peduncles about equal- 
ling the leaves and bibracteolate near the base: sepals lanceo- 
late, either naked or ciliolate: corolla about ? inch long, of a 
fine lavender-blue, the paired petals, especially the two up- 
permost, obovate-rhomboidal, the laterals white at base and 
strongly bearded with indistinetly clavellate hairs, the keel- 
petal shorter and narrower than the others, more or less 
conduplicate or convolute especially at apex, white at base, 
and purple-veined above the white: summer foliage less 
broad in proportion to its length than in V. cuspidata and 
more apt to be cucullate: apetalous flowers on short but 
nearly or altogether hypogeous peduncles. 
A common Canadian violet of woods and thickets, re- 
ferred by me to V. cuspidata when first seen in dried mate- 
rial; also commented upon by Mr. J. M. Macoun at page 
186 of volume xii of the Ottawa Naturalist (Jan., 1899), under 
that name. But the description given is only a reprint of 
that of V. cuspidata and is now fouud to be very inappli- 
cable to the plant of Canadian habitat. The plates issued 
by Mr. Macoun are also, most unfortunately, and through
