32 R. Tuora (Lin. spe. 775.) leaves quite smooth, radical

The root of this plant is reported to be extremely acrid and 
poisonous ; its juice having been used formerly by the Swiss 
hunters of wild beasts, to envenom their darts, whose wound, by 
that means, becomes speedily fatal and incurable. Hence the 
name from Sopa, phthora, corruption or venom.
