Native. Inundatal, Paludal. The observations made 

 under the preceding species, M. rotundifolia, will indicate 

 that the localities of this one also are liable to doubt in 

 various instances ; although it is probable that the more 

 frequent error between them arises from giving the name 

 of M. rotundifolia to specimens of the present species ; 

 thus causing the fonner to appear less rare, and the present 

 species to appear more rare, than the facts would waiTant 

 if they were clearly and fully ascertained. Suspected to 

 have been inti'oduced to Moray and Forfar. Is it truly 

 wild at Killin, Perthshire, and in Arran ? If so, we may say 

 cends to 150 yards in the East Highland province, on faith 

 of the fonner locality.

Denizen. Paludal, Inundatal, &c. In all likelihood, 

 introduced to most of its recorded localities ; but here, as 

 in so many other instances, that mischievous habit with 

 botanical collectors, of suppressing or misrepresenting facts, 

 in order to make out an apparently favorable case for belief 

 in the nativity of species, interposes a very serious bar 

 against the progress of scientific truth in matters relating 

 to the distribution of plants. On the whole, the evidence
