Native. Littoral. The second of these species has 

 only very recently been distinguished from T. junceum 

 by the botanists of England, and its localities, &c. cannot 

 therefore be separated from those of T. junceum, under 

 the name of which they have doubtless always been re- 

 corded. I cannot even yet satisfactorily assign the speci- 

 mens in my own herbarium to the respective species. 

 The aggregate species (junceum and laxum, — one or other, 

 or both) has been recorded from the coasts of every pro- 

 vince, either in j)rint or by unpublished notes. It is also 

 named in Mr. Buckman's short list of littoral and sub- 

 littoral plants, which occur in the vale of the Severn, 

 many miles from the sea, and are suggested by him, with 

 considerable show of i^lausibility, to be the remains of a 

 maritime flora, formerly bordering a strait of the sea, then 

 running between England and Wales. T. laxum is said 

 to have been found in Sussex (Mr. Mitten !), Pembroke 

 (Mr. Babington), Lincoln (H. C. Watson), Durham (Mr. 

 Hort), Edinburgh (Dr. Balfour), Arran (JVIr. Babington).
