383 Callitriche verna. 



Counties all, except 42 74 93 

 105 106 107. Such is the 

 recorded distribution of C. 

 verna ; but no doubt more 

 or less including the two 

 other very unsatisfactory 

 species treated underneath 

 as nos. 384 and 385. 



384 Callitriche platycarpa. 



Counties all, from 1 to 112; 

 but with many exceptions 



to the records through bota- 

 nists not generally distin- 

 guishing this from the pre- 

 ceding. My list of counties 

 affords no sufficient autho- 

 rities for the following : 4

 84 90 93 95 97 103 106 

 to 109 ; in some of these 

 counties very likely seen by 

 myself without special notes 

 being kept.

(C. pedunculata). 



Counties all, from 1 to 112 ; 

 but with still more nume- 

 rous exceptions. Several 

 segregates are included, very 

 dubiously distinct, and va- 

 riously named at different 

 dates. The plant varies 

 much according to its situa- 

 tions, in deep water, in
