Native. Septal, &c. Mr. Gardiner indicates one lo- 

 cality for each of these alleged species ; considering the S. 

 triandra as "probably planted," and passing the S. amyg- 

 dalina without remark. In the Edinburgh Catalogue S. 

 triandra is entered as a native, though rare. These are

 for either of the species. Winch gives both as natives of 

 the Tyne province. S. triandra is frequent in some of the 

 southern counties of England, though doubtless introduced 

 to many of its present localities. This, like some other 

 species, might be as correctly referred to the paludal, as to 

 the septal, plants.
