This species is nearly allied to P. geoides L e h m. Potent. 

 p. 58, t. 2, but differs in its entire stipules, Sec, It Uby many 

 of our Botanists supposed to be the P. fiennsylvanica ; but. 

 according to Sir J. E. S m i t A, to whom I sent specimens for 

 examination, it is totally unlike that species, or any other that 

 he had seen. The nectary or disk on which the stamens are 

 inserted, is a remarkable character in this genus, and is not no- 

 ticed by Lehmann \\\ his recent elaborate Monography ot 

 PoTENTiLLAc On accouut of this peculiarity Dr. Big e lou 

 proposes it as a new genus under the name of Bootia.I
