On Sciadium ArbuSCUla, Braun.— This very rare, interesting, 

 and minute plant, was collected in the Curling Pond, Haughton, by Mrs. 

 Farquharson, in the beginning of last winter. This, as far as I can make 

 out, is the first time it has been found in Britain. True, Dr. Cooke, in his 

 " British Fresh-Water Algae," figures it, but in the text, he has no reference 

 to locality, and hence we infer that he knew of none, and that he inserted it 

 as a plant likely enough to be found in this country. It was originally de- 

 tected in Germany, and more recently in Sweden, and in the United States of 

 America. It is usually found among the leaves of Afyriophylium, and similar 

 plants. I picked it up this spring in a pool between Loch Kinnord and Cam- 

 bus o' May, in a fragmentary condition, and no doubt it will be found in 

 other localities. John Roy.
