FLORA OF THE IVEL VALLEY, BEDFORDSHIRE. 



839 



instance the bed of a lock was almost solely occupied by Sagittarla 

 in full blossom. 



When the visit was projected, lively hopes were entertained that 

 some CharacecB would be obtained, but although the stream was 

 repeatedly dredged, not the least trace of these plants could be 

 found. A similar experience fell to the lot of Mr. T. B. Blow and 

 Mr. H. Groves, who visited the Shefford district to seek for Chara- 

 ce(B, but found none. 



The primary object of the visit was to make one step in the 

 direction of the production of a Flora of Bedfordshire that should 

 be based on the river systems. Having collected many data in 

 reference to the plants growing in the catchment areas of the Colne 

 and Lea, of the Thames river system, and also of the Ousel, Flitt, 

 Crawley Brook, as well as the main stream of the Ouse system, it 

 was felt to be desirable to continue the observation towards the east 

 of the county where the Ivel is situated. It need hardly be said 

 that many other very common plants were seen, in addition to those 

 now enumerated.
