which in this conntrj grows only near the sea or in 

 marshes washed by tidal rivers. Unhappily, our 

 interest in the question whether P. littoralis truly

 only in our herbaria. 



GASTRIDIUM, Pal. de Beauv. 



884. Gr. lendigerum, Gaud. 



Native; scattered over a very small area on the 

 Gloucestershire bank of the Avon, below Bristol. 

 There is little doubt that all the published records 

 of the occurrence of this grass on St. Vincent's 

 Rocks, Durdham Down, and the bank of Avon, 

 may be referred to the same small tract of lime- 

 stone upon which it now grows ; although its ex- 

 tent is less than it was formerly. Mr. T. B. Flower 

 tells us that he used to find it behind the New 

 Hotwell House, long since removed. That spot is 

 situate on the river-bank, some distance from the 

 present station for the plant. VII. VIII. 



HOLCUS, Lvin. 



885. H. lanatus, L. 



Native ; in meadows, pastures, hedge-banks, and 

 waste places. Very common and universally dis- 

 tributed. VI. VII. 



886. H. mollis, L. 



Native ; in woods, hedge-banks, and pastures, very 

 much less common than the preceding species.
