imbricated, brown ; inner ones (fig. 2.) the longest, generally the 
two or sometimes three innermost ones are floriferous, of which one

This plant, which is rare in most parts of England, and still 
more rare in Scotland, is said to be so plentiful in the Fens of 
Cambridgeshire, as to cover hundreds of acres, to the total exclu- 
sion of all other plants. It serves for thatching instead of straw, 
and often grows in such quantities in pools, as to form floating 
islands. It is said to be hurtful to cows. 
'the drawing for the accompanying plate was made from a 
specimen gathered in Anglesea, by Mr. Owen Griffith, in Sept. 
1842, and kindly communicated to me by J. Satterfield, Esq. 
I have also received specimens of it from Mr. W. Willis, of 
Charlestown near St. Austell, Cornwall.
