Native. Agrestal, Viatical, &c. Has probably been 

 carried to the altitude indicated, by the upward progress 

 of habitation and cultivation. Carduus (Cirsiura) setosus 

 has occurred near Culross, in Fife, apparently plentiful and 

 during some successive years ; but whether a native variety, 

 or one introduced to that very " infected " county, I am 

 unprepared to say. Mr. Babington (Man. Brit. Bot.) men- 

 tions a variety " latifolius," which he queries may be a 

 distinct species, found in Derbyshire.
