80. ALISMACE.E. 477 



reford (Duncuinbe, quoted in B. G.), Glamorgan (Mr. T. 

 B. Flower; Mr. J. W. Gutch), Merioneth (E. F. and B. 

 G.), Caernarvon (Mr. C. C. Babington, &c.), Anglesea 

 (Davies, W. B.), York (Teesdale, in B. G.), Cumberland 

 (B. G.), Wigton (Hook. Brit. Flo.). From these ten I have 

 selected the six above mentioned, as being most probable 

 or best supported ; the other four will require verification 

 by trustworthy observers. While the species is thus 

 clearly one of western distribution, it cannot be quite ac- 

 curately classed with the Atlantic or south-western group.

 any other botanist among the many who have visited that 

 marsh.
