Aquilegia vulgaris now seems to be a frequent Norfolk fen 

 plant. The flowers vary greatly in colour — white, blue or red to 

 nearly chocolate. 



Habenaria conopsea grows with its roots under water. The 

 flowers are larger but fewer than when it grows in dry localities. 



Foulden and Seaming Commons, Stow Bedon and Wretham 

 marshland. 



For these localities I shall only give additional uncommon 

 plants as I have given above a typical flora. 



They are heath- in contradistinction to meadow-marshes. At 

 Stow Bedon there are many marshy pools amongst sandy hillocks, 

 Foulden is in parts similar, but hillocks are chalk, and bear a 

 characteristic chalk flora : —

The Droseras grow among Hypnum and not in connection 

 with Sphagnum, although that occurs in some quantity in each 

 locality. 



At Seaming in May, 1912, I collected a monstrous form of 

 Cardamine pratensis, in which, after seeding of the plant, each 

 seed had produced a double flower, without stamens or pistil. 

 Professor F. W. Oliver, to whom the matter was referred, remarked 

 that "such a happening may be rare or even unique, but the latter
