the attention of the phvsician, I have given a figure of 
it, it being frequently confounded with 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-footy in case of accidents hap- 
pening, and usually call the other species of Prenan- 
thes False Lions-foot. Gronovius, in his Flora, 
pag. 113, mentions Dr. Witt’s Snake-root under P. aum 
tumnalis or Willdenow’s ruVicunday as a remedy for 
the bite of the rattlesnake; which shows that he had 
information of the use made of this plant, though 
"" he did not know the genuine species. In the 
Banksian 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.”
