Native. Paludal. A local plant, with its few localities 

 widely scattered. It has heen long known in Shropshire 

 and Yorkshire. Dr. J. B. Wood and others find it in 

 Cheshire and Lancashire. My herbarium is indebted to 

 Mr. Varenne and Mr. Bentall, for specimens from Essex. 

 And I have gathered it in one spot in Surrey, that is, in 

 a field close by the river and canal bridge at Wej^bridge, 

 where drainage may shortly destroy it. These are the 

 only six counties in which I am aware of localities for C. 

 elongata, a plant which seems not unlikely to be found 

 also in some of the intermediate counties.
