Stock perennial, with stout, erect stems, 

 2 to 3 feet high. Leaves divided into 3 

 large, broad segments, which are again 

 deeply 3-lobed and coarsely toothed, 3 

 to 4 inches long, and often rather rough 

 with a few short hairs, but much less so 

 than in Heracleum ; the lateral segments 

 descend much lower along the leafstalk 

 on the outer than on the inner side. Um- 

 bels large, terminal, of 40 to 50 rays, 

 without any general involucre, and only 

 a few very slender small bracts to the par- 

 tial ones. Flowers white. Fruit nearly 

 orbicular, about 2 lines diameter. 



A native of mountain pastures in cen- 

 tral Europe ; formerly much cultivated 

 as a pot-herb, and now naturalized in se- 

 veral parts of northern Europe as well as 

 north of England and in Scotland. Fl. early summer.

 and west central Asia.
