RANUNCULACE^. 



1. Anemone cylindrica {sp. nov.) ; sericeo-pubescens ; foliis 

 ternatim sectis, segmentis lateralibus bipartitis, intermedio Iri- 

 fido, laciniis lineari-lanceolatis apice inciso-dentatis, involucra- 

 libus petiolatis conformibus ; inyolucellis nullis ; sepalis obo- 

 vatis, obtusis, subcoriaceis ; carpellis lanatis, in capitulum cy- 

 lindricum congestis. 



Root perennial, fibrose-fasciculate, 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, S — 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 cylindrical elongated capi- 

 tulum, about an inch in length. 



Hab. In dry pine barrens, near Oneida Lake, New York. 

 Flowers in June.

 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
