 Fragaria n. 1 126. Hall. Hist. d. 2. 5 1 . 



In osier holts and spongy meadows, frequent. 



Perennial. June, July. 



Root tapering. Stems several, procumbent, trailing to a great ex- 

 tent, round, smooth, taking root at their joints, where also they 

 produce leaves and flowers. Leaves from 3 to 6 inches long, 

 interruptedly pinnate, in a somewhat lyrate manner, deeply and 

 sharply serrated ; clothed most abundantly beneath with splendid 

 silvery hairs ; the upper side deep green, either smooth or hairy, 

 Fl. large, bright yellow, each on a long simple stalk, mostly erect. 

 Cal. hairy j its outer segments generally notched at each side, 

 approaching in that respect to Fragaria indica of authors, Nestl. 

 Potent. 21. See Duchesnea, Rees's Cycl. v. 39. suppl. Germens 

 very hairy. Seeds seldom perfected. 



Dr. Nestler's citation of Lobel, Hist. 39, which Mr. Haller jun. 

 copies, has cost me no small pains to unraveL Morison's plant 

 is not a variety. 



It is this species which, according to Linnaeus, indicates clay under 

 the surface, and not P. argentea. Mr. Rose in his Elements of 

 Botany 382, was misled by the name Argentina. 



3. P. rupestris. Strawberry-flowered Cinquefoii. 

 Leaves lyrate-pinnate ; leaflets seven, five, or three, ovate, 



serrated, hairy. Stem erect.
