circumstance of its gregariousness, and it is also an index 

 of the persistence of the plant in its present locality. It 

 must have been established for several years to account 

 for the size of the patches, and it is surprising that it has 

 not been detected and described earlier. As far as my 

 observation has gone the species is confined to that 

 portion of the sandhills which lies off the South Drive 

 both to the north and to the south of St. Thomas's Church. 

 But it is only a question of time how soon the localit)- 

 will be built over, as the plot is on sale, and three of its 

 sides already front roads or dwelling-houses. It ma}' 

 occur on other parts of the sandhills which I have not 

 yet explored, such as the parts near to Fairhaven and 

 Common Side, and the long stretch of level land which 

 lies to the south of the Golf House ; but from the railway 

 certain parts of the land look quite suitable for the 

 occurrence of the plant. 



It is not easy to determine in what way it has 

 established its foot-hold at St. Anne's. The older residents 

 inform me that at one time the site was used for hen-pens 

 and hen-runs, similar to those which are found at the 

 southern end of the same group of sandhills, and I hazard 

 the conjecture that the fowls have been fed, at times, 

 with the grain-sweepings of the docks, from Fleetwood 

 or Liverpool, in which fruits of the Amhrosia have been 

 included. 



There are a number of interesting native plants 

 associated with it on the St. Anne's sandhills, besides 

 the ubiquitous Salix repens, L., and Rubus ccesms, L., 

 viz. : Reseda hitea, L. ; Viola Curtisii, Forster ; Cicho7-iuin 

 Intybus, L. ; Hieracijini tiinbellatiim, L. ; Convolviihis 

 arvensis, I^. ; EcJduvi vjilgare, L. ; Bartsia viscosa, L. ; 

 Thymus Sei'pyllum, Fr. ; Polygomim Convolvulus, L., &c. 

 But there are several others growing with the A7nbrosia
