12 Bailey, Adventitious Vegetation of St.Annes-on-the-Sea. 



somewhat starved state. I have collected this species, 

 of course as a casual, on the opposite shore, as at Formby ; 

 it is often found on railway banks, sidings, and goods 

 yards. It is a European plant, naturalised in the United 

 States, and therefore likely to occur with other casuals 

 from that country. 



Solatium rostratum, Dunal. This yellow-flowered 

 spiny-stemmed nightshade of the American prairies was 

 not infrequent. It is a plant which Mr. J. A. Wheldon 

 tells me has been found in several parts of South 

 Lancashire. I named it from cultivated examples in 

 my herbarium from Strasbourg. Buffalo-bur, bull-nettle, 

 Texas thistle, buffalo thistle, Mexican thistle, Colorado- 

 bur, spiny nightshade, are some of the cognomens applied 

 to it in the United States. 



Solatium trifiorum, Nutt, is another sand-loving 

 prairie nightshade, with small whitish straw-coloured 

 flowers, which occurred with ripe fruit, but examples 

 were not numerous. 



Lycopersicum esculentum, Mill. = Lycopersicon Lyco- 

 persicon (Linn.), Karst, might be omitted from this list, as 

 the tomato is so frequently found on waste heaps in this 

 country ; but it is also so fully naturalised in the United 

 States that its association with the other casuals suggests 

 its inclusion with them, as derived from the same over- 

 sea source. 



Leonurus Cardiaca, Linn,, was collected in September, 

 1901, close to Ansdell, and in no way associated with the 

 other plants here named. Nevertheless, it is naturalised 

 in the United States, and may have been introduced with 

 grain siftings of American origin.
