species which 1 have ever seen. They fall under var. vulgaris 
Doell. — J. E. Lousley. The sheets included with these 
specimens bear impressions of the stem section of the plant 
taken about lOcms. from the base of the stem, and are intended 
to show its acutely triquetrous shape. This is also indicated 
by the splits which appear in the stems during pressing. The 
rhizomes are worthy of study and comparison with those of 
S. lacustris andx$. carinatus. — J. E. Lousley. Has long been 
there, favoured b}’ the brackish, tidal water. The impressions 
of the cross section of the stem will be useful to go with the 
dried specimens. — J. Fraser.
