Five years ago, in the Society's Manchester Memoirs, 

 vol. 47, No. 2, 1902, the occurrence was reported of four 

 somewhat conspicuous alien plants on the sandhills of 

 St. Anne's. In the subsequent years many other non- 

 aboriginal plants have been noticed in the same locality, 

 and the object of the present communication is to put 

 their names on record. 



The source of this adventitious flora was puzzling, 

 but there seems no reason to doubt that the sweepings of 

 corn ships and of docks, and the siftings of grain imports, 

 used as food for poultry, are the main source of the species 

 about to be enumerated. The sandhills of the St. Anne's 

 coast have long been utilised for housing poultry, and, 

 with the rapid advance of the township in population, the 

 building area has extended, and more and more of the 

 sandhills has been absorbed, or removed, in the process. 

 When the hen-pens are taken down, and the ground- 

 surface is disturbed, plants spring up quite different from 

 the herbage native to the neighbourhood. Few of these 

 aliens reach maturity, as the passage of workmen and 

 vehicles over them, in numerous cases, destroys large 

 numbers, and the surprise is that so many species remain 

 to reward the search of the botanist. A list of more than 

 forty species is quite worthy of a large ballast-discharging 

 port.
