 carnafa L. for the Ivel' basin. The majority of our plants have 

 unspotted leaves. On Oughton Head Common in 1915 I could only 

 find a few with spotted leaves. The leaves, though often naiTOw and 

 hooded, are not of the short rather rigid type narrowing all the way 

 from the base, I have never seen a plant with flesh-coloured flowers 

 in this district. The bracts vary much in length.
