881. A. alba, L. 



Native ; in marshes and damp pastures everywhere. 

 The var. J3 stolonifera has been gathered on sea-sand 

 at Burnham and Weston-super-Mare, and on mud 

 in the New Cut by Bathurst Wharf. VII. 



POLYPOGON, Desf. 



882. P. monspeliensis, Desf. 



Alien. Until a few years ago this beautiful grass was 

 connected with the Bristol Flora solely through a 

 communication (" Near Bristol ") made by Miss 

 Alice Worsley (afterwards Mrs. Russell) to Mr. 

 Hewett Watson, and published in the New Botanists' 

 Guide, 1835. In 1883 it was found growing luxuri- 

 antly upon the material dredged from the bed of 

 the Avon and from the basins, which had been 

 placed the year before in a river-side quarry. 

 It has continued there to the present time. 

 Although the circumstances under which it was 

 gathered by Miss Worsley are unknown, the re 

 currence of this species on the bank of the river 

 goes toward showing that it may formerly have 

 been an inhabitant of the Avon valley. 



883. P. littoralis, 8m. 



Possibly native in St. Philip's Marsh, G., where we 

 have known it many years. 



In weighing the claim of this plant to be indigenous 

 in a locality where the original soil is in process of 

 conversion into bricks and pottery, and of replace- 

 ment by mounds of ashes, rubbish, and refuse of 

 all sorts, it should be borne in mind that, in its 

 primitive condition, St. Philip's Marsh undoubtedly 

 was a fitting station for the species under notice,
