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. OENiTHODES. 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 Eock 

 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 the other. 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. variabilis, 

 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 toll 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 3} inches long, a little wider than that across
