be called V. palmata, Linn. is very different from this, and is 
palmated, which V. vespertilionis never is. There are other 
names, V. asarifolia, Pursh, and V. congener, Le Conte, that may 
perhaps embrace among other different forms, this also. 
V. ORNITHODES. Mode of growth as in the last, the leaves and 
flowers as few and strict, all far more slender, even taller, 5 or 6 
inches high, the petioles long-villous, but not densely so; foliage 
at all stages much smaller, the very earliest reniform, the leaf 
accompanying the flowers, lobed but cucullate, concealing its 
lobes; corolla more than an inch long, its petals narrower, 
spatulate-oblong, the sepals also longer and narrower and nearly 
or quite devoid of ciliation. Summer state of plant not large in 
proportion, 7 to 10 inches high, the foliage various, but con- 
figuration always peculiar, the undivided leaves somewhat tri- 
angular or even semiorbicular, the largest hardly 2 inches wide, 
the divided ones always or nearly always 3-lobed or -parted, with 
middle lobe largest, oval or oblong, subentire, the pair spreading 
away from this, leaving almost rectangular sinuses, crenate on 
the outer margin and curiously bird-wing-like in cut, the 
leaf as a whole suggesting the outline of a bird with spread 
wings. 
On open hills bordering woods and looking eastward, in Rock 
Creek Park, D. C., also in like situations on the Virginian side of 
the Potomac, below Chain Bridge, April to June, 1906. 
The relations between these two types last defined I, of course 
do not know. They may be subspecific descendants of some 
other type known or unknown. They are not, I think, varieties 
one of theother. Each of them, now after long study, confirms me 
in the view I took when studying that kindred plant of the 
mountain sides above Harper’s Ferry, which I called V. variadilis, 
namely, that one must allow in this group, without even varietal 
distinction, plants with all leaves undivided, and other plants 
with leaves all, and variously, cut or cleft or lobed. 
V. FONTANA. Larger plants 9 to 11 inches high at petaliferous 
flowering, the flowers surpassing the foliage by an inch or more; 
herbage light-green, glabrous, subsucculent : leaves cordate-ovate, 
obtuse, about 24 inches long, a little wider than that across
