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-foot, in case of accidents hap-

thes False Lion s -foot. Gronovius, in his Flora, 
pag. 1 13, mentions Dr. Witt’s Snake-root under P. au- 
tumnalis or Willdenow’s rubicunda , as a remedy for

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 rubicunda , 
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.”
