Though this plant is included in most systematic works on the 

 British Alg£e, it evidently has no just claim on our Flora, all 

 the specimens hitherto found on these shores having been doubt- 

 less drifted thither by currents from the Atlantic. It is occa- 

 sionally cast ashore on the Orkneys along with S. vulgar e, but 

 has not been noticed on the west of Ireland, where, nevertheless, 

 tropical drifts of other descriptions are not uncommon.
