the attention of the physician, I have given a figure of 

 it, it being frequently confounded wuh another spe- 

 cies of this genus, which probably may not have quite 

 so strong an effect, as the inhabitants are very careful 

 to have the true Lions-fvot, in case of accidents hap- 

 pening, and usually call the other species of Prenan- 

 thes False Lions-foot. Gronovius, in his Flora, 

 pag. 1 13, mentions Dr. Witt's Snake-root under P. au~ 

 iumnalh or Willdenow's ruhicunda, as a remedy for 

 the bite of the rattlesnake; vi'hich shows that he had 

 information of the use made of this plant, though 

 he did not know the genuine species. In the 

 Eanksian Herbarium is a specimen of P. rulicunda, 

 with the following note in the hand-writing of Clay- 

 ton : " This is the rattlesnake-root that Dr. Witt 

 supposes to be the best cure for the bite of the snake, 

 a very odd plant, hardly two leaves alike upon a plant, 

 as to shape or the indentings of the leaves."
