very peculiar, giving at first the impression that they are very 

 minute, viz. '004-7 mm. across, but such are ultimately seen 

 to be the dimensions of particles of chlorophyll, whereas the 

 cells proper are bluntly quadrate, close, with very thin 

 transparent walls, containing four particles of chlorophyll in 

 each, and ■oo9-'Oi4 mm. across, ultimately dark and opaque; 

 such are found throughout the rest of the leaf, the larger next 

 the nerve. Leaves are minutely papillose, more especially in 

 their upper third, less frequently on the margin ; height about 

 •0025 mm. 



At Onich near seashore in two places ; in one place similarly 

 situated at Gairloch, 1911. 



Scottish Forms of Sparganium. By Arthur 

 Bennett, A.L.S. 



Following up the notes in the January number, I here give 

 the forms of this genus, which I have from Scotland. 



The specimens have all been seen by the late Mr. Beeby 

 and by Dr. Rothert. 



The names are given in the sense and value of the 

 describers, although opinions may differ as to their being 

 varieties, states, etc.
