o o Involucral leaves slender-petioled ; leaf-segments broad. 



8. Anemone Virginiana, L. 



A. Virginiana, L., Sp. PI., 540 (1753). 



A. Ursula, Moench., Metb. Suppl., 105 (1802). 



Abelemis petiolaris, Raf. in Herb. Paris. 



Hairy, 60-90 cm. high, stout, branching at the primary involucre, the 

 lateral peduncles bearing secondary involucres. Radical leaves long-petioled, 

 broader than long, three parted, the divisions broadly cuneate-oblong, vari- 

 ously cleft and divided into acute, serrate lobes ; leaves of both primary and 

 secondary involucres similar, on petioles 25-50 mm. long ; sepals generally 

 5 [4—5], white or greenish, acute or obtuse; flower 20-40 mm. broad; head 

 of fruit oblong, 20-30 mm. long ; achenia compressed, woolly tipped with the 

 persistent subulate styles, which are about 1| mm. long. 



Distrib. New Brunswick and Nova Scotia to South Carolina, 

 west to Kansas and Manitoba and the Canadian Rocky Mountains 

 (Lyell, Macoun). 



Type of A. Virginiana, L., in Herb. Linn. 



In the British Museum Herbarium are two sheets, one from the 

 Chelsea Garden, 1722, the other from Kew, differing from typical 

 Virginiana by longer petioles to the involucral leaves, and narrow 

 leaf-segments. There is also a specimen of the same in the Herba- 

 rium of Columbia College, received from Meisner, grown in some 

 European garden. I have not seen wild specimens which would 

 exactly match these. 



X X Lateral peduncles usually naked ; involucral leaves slender-petioled. 



9. Anemone cylindrica, A. Gray. 



A. cylindrica, A. Gray, Ann. Lye. N. Y., iii, 221 (1836). 



Silky-hairy throughout, 30-70 cm. high, branched at the involucre. Radical 

 leaves tufted, long-petioled, broader than long, 3-5 parted, the divisions 

 cuneate-obovate or cuneate-oblanceolate, narrow ; those of the involucre 

 similar, on petioles about 1\ cm. long ; sepals 5-6, greenish-white, oblong, 

 generally obtuse ; flowers about 2 cm. broad, on elongated, generally naked 

 petioles ; head of fruit cylindrical, 2^-3 cm. or more in length ; achenia com- 

 pressed, woolly, tipped with the minute styles. 



Distrib. New Brunswick, eastern New England, Ontario, New 

 York, and northern New Jersey to Kansas and Manitoba; also 

 in the Black Hills and Rocky Mountains south to Colorado, and 

 New Mexico and in British Columbia (Macoun). Plants with
