PENTANDRIAe MONOGYNIA. - 149 
The V. papilionacea, and V.asarifolia of Pursh, are 
probably ambiguous varieties of V. cuczllata and V. pal- 
mata. Whether V. claydestina of the same author be really 
a distinct species is also equally uncertain, it appears to 
me nothing more than a smoother variety of V. villosa, 
if the petals of this plant were indeed “chocolate brown,” 
that alone would be a sufficient character, but such ano- 
malies are scarcely to be expected. ; 
7. rotundifolia. Michaux, excluding the synonym of 
Pursh’s V. clandestinu. In this species, so accurately de- 
scribed by Michaux, the leaves are unusually thick, larges 
and round, constantly appressed to the ground, with a 
pubescent petiole, and the sinus more closed than in any 
other species; the flowers, which are of a pale yellow, 
appear before the complete expansion of the leaves, upon 
‘short peduncles; the segments of the calix are oblong; 
obtuse; the 2 lateral petals are a little bearded and striate; 
striz, 3 upon each, the uppermost interrupted by the line 
of pubescence; the lowest petal is uncommonly small, 
and also striate, the striz bifid and crossed by 2 yellow 
callous converging lines near the base; nectary almost 
obliterated; style short and thick, capitulum of the stig- 
ma small and smoot!:, recurved at the apex, but without 
rostrum. Las. On the shady and rocky banks of Wisha- 
hikon creek, about 8 miles from Philadelphia, where it 
was also found by Mr: Rafinesque; always under the shade 
of .Qhies canadensis; in-similar situations I have also seen 
it in the mountains of North Carolina. ; 
8. blanda. Leaves nearly smooth, or slightly pubescent 
on the upper side, petiole and under side entirely glabrous, 
nerves pinnate, also Smooth; flowers white, and odorous, 
see ments of the calix linear-oblong, obtuse; stigma capi- 
tate, depressed, recurved, acutely margined around, pe- 
tals all smooth. eu oN Spe, 
9, primnlifolia. LINN. Persoon, Elliott, excluding the | 
‘ir. Pursh, which appertains to another spe- 
cies: This plant is very nearly allied to V. lanceolata, and 
as such has probably been considered by Walter, Michaux, 
and Pursh; both of them are indigenous to Siberia as 
wellas North America. It also makes a near approach to 
- V. blanda. Leaves oblong, subcordate, crenate, obtuse, the 
base remarkably and abruptly decurrent on the petiole, 
33 do to resemble the leaves of pee. Seto nerves pin- 
“nate, 
mid-rib on the upper side of the with a few scat- 
~ tered hairs; petiole on the under side as well as the nerves 
the same side, and the s hairy; segments of the —
