 Tall Marsh Sow-thistle. Petiv. H. Brit. t.XA.f.l. 



In marshes near the banks of large rivers. 



About Greenwich and Blackwall. Ray, Curtis. Near Streatham 

 ferry, in the isle of Ely. Relhan. 



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 herb being moreover twice 

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

 little paler. Stern cylindrical, though angular and furrowed, 

 scarcely branched, leafy, hollow, with many transverse internal 

 partitions. Leaves large, deeply pinnatitid, 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 ; 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. arvensis. Corn Sow-thistle. 



Flower-stalks and calyx bristly, somewhat umbellate. Leaves 

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

 creeping.
