Between Upper and Lower Heyford, growing with C. amara and U. 
pratensis this year occurred a hybrid, Cardamine amara pratensis. 
The foliage was identical with amara, the flowers darker in colour than 
pratensis, having more of a purplish tint, but slightly smaller than amara ° 
the anthers were violet as in amara, but the style was nearer that of 
pratensis. There appears to be no reference to this hybrid in the Euro- 
pean Floras. 
C’. amara has occasionally the outer side of petals tinged with pink.
