Very variable. The cliff form is very constant, and very 

 different from the form of open, sandy fields. The bracts 

 vary in colour from almost black to a dehcate fawn-colour. 

 The leaves also vary much in breadth. The forms seem in- 

 extricable at present, even with the help of Mr. F. N. 

 Williams' elaborate examination in his " Prodromi FloriE 

 Britannicee Specimen," and I follow Mr. Arthur Bennett's 

 advice and " call them all C. nigra for safety." 



2. C. SCABIOSA L. 



Native '? perhaps only a casual. Sandy waste places. Very 

 rare. July, August,
