*Heracleum pubescens. This species bears yel- 

 lowish-white flowers, in umbels about a foot in diameter,

 leaves are very large, roughish on the upper side, and 

 much divided into elliptical segments, which are pointed 

 and stand close together. Crimea. 



*Heraclenm villosum. A species distinguished by 

 its very downy and fringed fruit, with robust stems, 6-j ft. 

 high or more. Leaves broad, much divided, the segments 

 coarsely toothed, covered with a whitish down on the

*Heracleum Wilhelmsii. The leaves of this species

 The stem is more than 6% ft. high, and bears whitish 

 flowers, in umbels from 10 ins. to 12 ins. in diameter.
