figured in 'English Botany,' 1st eel., and thus noticed: — 

 "Found by Mr. G. Don in 1795 or 1796 by the side of 

 rivulets in marshy ground among the mountains of Angus- 

 shire, but very rarely." No one has since found it in Forfar, 

 and it has dropped out of our Floras as a mistake. It is 

 widely distributed over the world from Europe and North 

 America to New Zealand, where, however, my friend Mr. 

 Cheeseman now thinks it may have been introduced. 



Carex trinervis, Degland, found on the Norfolk coast in 1869 

 or 1870 by Mr. H. G. Glasspoole, amongst whose duplicates 

 the specimens had remained until December, 1883, when, in 

 looking over his Norfolk Plants, I found four specimens of 

 this species. It is a Western European species, occurring on 

 the coast sand-dunes in Denmark, Holland, the East and West 

 Friesian Islands, Belgium, France, and sparingly in Portugal. 



Carex acuta, Linn., var. j)rolixa, Fr. — Among Mr. Glass- 

 poole's series of Norfolk plants I found a specimen of this 

 gathered as long ago as 1844 by Mr. Priest, in marshes at 

 Lakenham, Norfolk. These marshes are now drained and 

 partly built over, I am informed by the Eev. E. F. Linton, of 

 Sprowston, near Norwich. In this species the glumes are 

 considerably longer than the fruit, and the fruit is more like 

 that of stricta. 



Carex acuta, L., var. turfosa Fr. — Two specimens gathered 

 in Cambridgeshire by Mr. Fryer. Dr. Almquist wi-ites, 

 "Almost turfosa"; and to other specimens, also gathered by 

 Mr. Fryer, he writes, "C. acuta, var. gracUescens, Almq." 

 This was also sent me by Mr. Beckwith from Shropshire. 



An interesting addition to the Irish Flora is Carex aquatilis, 

 Wahl., a northern sedge reaching beyond the Arctic Circle, 

 but coming south wherever the lines of temperature are com- 

 bined with local conditions. When this was first recorded as 

 a Scotch plant, doubt was expressed by our best botanists 

 whether it was the plant of Wahlenberg, but there is no 

 reason now to doubt this ; specimens from Siberia, Lapland, 

 and British North America are not distinguishable from 

 Scotch specimens from the mountains ; there is, however, a 

 variety, Watsoni, that has often been mistaken for C. acuta.
