SECT. III. TnbRA (<j>$opa, phthora, venom or corruption ; be- 

 cause the Swiss hunters of wild-boars use the roots of R. Thora 

 to envenom their darts) D. C. prod. 1. p. 30. Carpels smooth, 

 almost globose. Roots grumose. Flowers yellow. 



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

 ones stalked, stem ones sessile, kidney-shaped, crenated, floral 

 ones cut ; stem 2-3-flowered, smooth. If. . H. Native of the 

 Alps of Switzerland, Austria, Greece, Apennines, Carpathian 

 mountains, on rocks and in pastures near to the limits of perpetual 

 snow. Jacq. fl. aust. 5. t. 442 ; obs. 1. p. 25. t. 13. 



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 tyfyopa, phthora, corruption or venom.
