found it about Lake Winipeg and Red River, and intro- 

 duced it into the Garden of the Horticultural Society, 

 where our drawing was made in August last. 



It is a hardy perennial, with a handsome foliage and not 

 inelegant inflorescence. 



Dr. Torrey cites to this species, with a mark of doubt, 

 the Geum agrimonoides of Pursh,- said by that writer to 

 have a white flower. We have examined the Lambertian 

 Herbarium, in which this plant is deposited, and have re- 

 cognised it as a species previously well known to us, which 

 we believe, although an undoubted Potentilla, to be distinct 

 from this. Mr. Don at the same time pointed out the 

 original specimen of P. arguta of Pursh, of which we think 

 with him P. confertiflora is a synonym. 



The following is Dr. Torrey's description of the plant. 



Root thick, fuscous ; whole plant with a dense browniish 

 pubescence, and when young viscid. Stems numerous, 

 about 2 feet high, terete, striate. Leaves mostly in tufts 

 about the root, on very long petioles ; leaflets 5-7 pairs, an 

 inch and a half or more in length, often with foliaceous 

 bracts, or minute leaflets, at the base, coarsely and doubly 

 serrate ; the serratures rather obtuse. Flowers crowded in 

 a terminal panicle, nearly sessile. Exterior segments of 

 the calijx ovate-lanceolate, subincised ; the interior ovate 

 and acute. Petals yellowish-white. Stamens about 25; 

 filame/its inserted on the margin of a 5-lobed glandular disk, 

 which surrounds the base of the receptacle, and is adnate 

 to the calyx ; anthers subpeltate, margined. Receptacle 

 ovate, oblong, somewhat villous. Acines smooth and even.
