This is, after C. arvensis and C. lanceolatus, our commonest thistle. 

 White-flowered forms (/. alba) are by no means uncommon, as at 

 Cumnor {Morrison), Newbury, Bagley, Radley, Sandhurst, Windsor 

 Forest, Stubbing's Heath, &c. The anthodes are quite viscid. Th<^ 

 form with densely aggregated anthodes is the common one, but forms 

 with stalked anthodes are not uncommon ; some of the.se are possibly 

 owing to a cross with C. arvense.
