COMPOSITE 125, 



England, where it is, however, rather a common weed 

 of cultivated land. The presence of two varieties,, 

 uliginosus and marittjnus, in marshes and on seashores 

 respectively in South-East Europe, may be a clue to- 

 its origin.

 native there on bare sandy hills. 



Sonchus oleraceus, L. A common weed of cultivated

 rough bushy hillsides in England, though generally 

 recorded from such artificial surroundings as road- 

 sides, hedges, and field-borders.] 



Tragopogon crocifolius, L. A native of bare hills in
