an idea that the supposed Orobanche " lucorum," of Surrey, 

 may possibly be identical with Smith's O. caryophyllacea. 

 Otherwise, the South-east of Kent is the only habitat cer- 

 tainly ascertained for the present species. 



Orobanche lucorum, Braun. 



Area [3]. 



Incognit. It is very doubtful whether this name ought 

 to appear in lists of British plants ; but it was given to a 

 species which has been found in plenty near Epsom, in 

 Surrey. What that species truly is, I must confess myself 

 still unable to say with any feeling of confidence, although 

 I think it is not O. lucorum. Mr. Williamson, of the Royal 

 Gardens at Kew, gives the following directions for finding 

 the plant : — " From the back of the Grand Stand, on Ep- 

 som Race-course, proceed through the fields to the town 

 of Epsom, and the plant will be found among clover 

 (rarely among wheat) on the right hand side, on the back 

 of the hill." (July, 1846.)
