RANUNCULACE^. 
1. AxEMONE CYLixDRiCA {sp. nov.) ; sericeo-pubescens ; foliis 
ternatim sectis, segmentis lateralibus bipartitis, intermedio Iri- 
fido, laciniis lineari-lanceolatis apice inciso-dentatis, involucra- 
libus petiolatis conformibus ; involucellis nullis ; sepalis obo- 
vatis, obtusis, subcoriaceis ; carpellis lanatis, in capitulura cy- 
lindricum congestis. 
Root perennial, fibrose-fasdculate, Stem 1 — 3 feet high, and with the 
leaves, covered with an appressed silky pubescence. Radical leaves 
mostly on long petioles, finely and reticulately veined, light green 
above, paler beneath. Peduncles 2 — 6 (rarely 1), 1-flowered, all 
arising from the same point, 8 — 12 inches in length when the fruit is 
mature. Leaves of the involucre on short petioles, twice or three 
times the number of the peduncles, somewhat crowded. Involucels 
none. Sepals 5, pale yellowish-green, obovate, obtuse, somewhat 
coriaceous, sericeous beneath. Carpels acuminated into a very short 
style, with the apex deflexed ; in every part densely covered with a 
long, silky tomentum, and disposed in a cyUndrical elongated capi- 
tulum, about an inch in length. 
Hab. In dry pine barrens, near Oneida Lake, New York. 
Flowers in June. 
Obs. This species, although closely allied to A. Virginiana, 
Linn, is quite distinct. It must be referred to the section 
Anemonaxthea of De Cand., and be placed next to A. alba, 
which it resembles in many respects. From A. Virginiana it 
is readily distinguished by its more finely divided leaves, by the 
greater number and length of its peduncles, the absence of in- 
volucels, its obtuse sepals, and especially by its long, cylindri- 
cal and very woolly head of carpels. In this species also all
