 species. 



Carex teretiuscula Good. (C. diandra Schrank). At another 

 spot between Shapwick and Edington Droves, at some distance from 

 the original enclosure, 1912 ! And in still another, nearer Ashcott 

 Station, 1914 ! Mrs. Sandwith. 



C. Goodenovii Gay y&r. juncella Fries. A large tussock of this 

 well-marked form on the peat of Shapwick Moor, 1916 !

 Mr. Noel Sandwith, 1914 ! Plentiful near Hallatrow, 1917 ; B. V.

G. filiform is L. (C. lasiocarpa Ehrh.). In 1914, guided by 

 Mr. T. H. Green, I saw this in abundance at Thos. Clark's locality on 

 Glastonbury Moor, and Mr. H. S. Thompson reported it from three 

 enclosures to the westward. For an important discovery by this 

 acute observer of the hybrid X evohita Hartm. ■= filiformis X ri- 

 paria, not previously known in Britain, see Journ. Bot. 1915, 

 p. 309. 



G. vesicaria L. It is feared that the original station near Iron 

 Acton, G., was destroyed in 1910 by trimming the bank and clearing 

 the channel of the ditch in which it grew. Nothing bas been seen 

 of it lately. We always thought it unlikely that this little patch was 

 all that really existed in the Frome Valley, but the river has a 

 tortuous course, often through private policies, and in many places 

 its banks are not open to inspection. In May 1916, Mr. Harold 

 Eobbins, whilst fishing, discovered the plant's headqviarters in a 

 swamp at some little distance from Iron Acton and on the opposite 

 bank of the stream. The find is of importance, the sedge having no 

 other habitat in West Gloucester and being unknown in the county 

 of Somerset.

X Spartina Toicnsendi H. & J. Groves.- Introduced on the coast 

 of North Somerset for the purpose of mud-binding and protection of 

 low-lying marshland from inroads of the sea. The results bid fair to 

 prove as extraordinary as those achieved by this grass on the mud- 

 fiats of Poole Harbour, where its wonderful progress has been sys- 

 tematically survej'ed, photographed, and reported on b}" Mr. R. V. 

 Sherring. Three or four years ago I was informed b}'' the Eev. E. 

 Ellman that Spartina was being planted on the foreshore of the 

 Bristol Channel below Clevedon. The following account of this 

 proceeding and its sequel is based on details obtained from the local 

 Wharf Warden by Mr, F. Samson and from his own observations on 

 the spot. At that part of the Channel shore the scouring effect of 

 the tides on the existing mud-flats had been such that whereas
