NEW SPECIES OF VIOLA. 217 
V. EMARGINATA, var. SIMULATA. Plant of the size, habit and 
also exactly the leaf outline of V. sagittata, but of the deep color, 
peculiar smoothness and subsucculent texture of V. emarginata ; 
in summer stage 7 to 9 inches high, with petioles thrice as long 
as the blades, these 2 to 3 inches long, 14 inches broad across 
the quite roundedly sagittate base: petals narrower than in the 
type, not emarginate: capsules from apetalous flowers obovoid, 
ł inch long. 
On steep openly wooded slopes looking westward in Rock 
Creek Park, D. C., May 7 and 31, 1906, collected by the writer ; 
no typical plants found in the vicinity, nor even as yet by me in 
any part of Rock Creek Park or its outlying hills. 
V. VESPERTILIONIS. Reotstock stout, simple, at petaliferous 
flowering with about 3 leaves and 2 flowers, rarely more, all 
long-stalked and very erect, the peduncles slender and glabrous 
the petioles stout and villous-hirsute, the plant at this stage 3 
to 6 inches high, its earliest blades cordate and subreniform- 
cordate, the one developing with the corolla larger and com- 
monly hastate-lobed, never palmate; sepals subfalcate-oblong, 
obtuse, strongly hispid-ciliate toward the base; corolla rich 
violet, 2 inch long and the petals broad. Plant in early sum- 
mer with the one or two newer leaves extremely large, variously 
reniform in general outline, in robust plants 4 to more than 6 
inches wide and only 2 or 2} in length, often not lobed but 
coarsely crenate-toothed, more usually deeply 3-lobed, sinuses 
nearly or quite closed, the petioles of these leaves not villous, only 
sparingly hairy, but foliage pubescent, plant at this stage com- 
monly a foot high, or even more; the few apetalous flowers 
short-peduncled and, with the capsules, subterranean. 
Common in certain woods of the Potomac Basin in Maryland, 
Virginia and D. ©., my type specimens from about Brookland, 
D. C., April, May and June, 1897. I have never until now 
given this plant any specific name at all in my herbarium. 
The less cautious, and they who must first of all have a name 
for a form, have called this V. palmata, and V. palmata var. 
dilatata. The only violet that can with any degree of propriety
