Perennial. July, August. 



One of our largest herbaceous plants, being from 6 to 8 feet high. 



. Root fleshy, branching, not creeping, by which, as Mr. Curtis 

 very correctly observes, it differs essentially from the following 

 more common, species j the whole herh being moreover twite 

 or thrice as large, though ihejlowers are smaller, and usually a 

 little paler. Stem cylindrical, though angular and furrowed, 

 scarcely branched, leafy, hollow, with many transverse internal 

 partitions. Leaves large, deeply pinnatifid, smooth, except at 

 the edges, where they are fringed with copious, short, rigid, 

 bristly hairs ; their lobes narrow, acute, for the most part di- 

 rected downwards j the uppermost leaves simply hastate, ses- 

 sile, linear, serrated. Panicles terminal, umbellate or cymose, 

 their stalks rough with black, bristly, glandular hairs, as is like- 

 wise the calyx. Cor. lemon-coloured. Seeds furrowed. Down 

 simple, smooth. 



Haller only guessed this to be a variety of S. arvensis, without 

 - having compared them ; a rather rash mode of judging, calcu- 

 lated to mislead all who practise it. 



3. S. ai'vensis. Corn Sow-thistle. 



Flower-stalks and calyx bristly, somewhat umbel late. Leaves 

 runcinate, finely toothed, heart-shaped at the base. Root 

 creeping.
