The other, S. alterniflora, was discovered by Loiseleur in the 
estuary of the River Adour near Bayonne in 1803, and then in 1829 
by Borrer in the Itchen River near Southampton. A very com- 
plete account of it as it appeared there in 1836 was given by 
Bromfield.* It has since then spread to some distance north of 
Northam Bridge in the Itchen River and to the Southampton Water 
as far as the Titchfield River on the eastern, and from Hythe to 
Redbridge on the western bank and from there to Millbrook. In 
France the grass has extended its area over a coast line of about 
extreme points of which are over fifty miles distant. It would be 
tedious to trace the advance in detail; a few instances may ce. 
In 1893 [Rey. E. F.] Linton found “several strong patches ” of it 
lontagu ass _ there was no trace of it in the Beaulieu 
River ; now it predominates everywhere to beyond Buckler’s Hard, 
to quote from a manuscript report by Mr. J. F. Rayner, of
