The most interesting aliens are OEnothera hamarhiana, the striking 

 Evening Primrose, which still exists in great profusion on the St. Annes dunes, 

 Ambrosia artemisfolia (American Wormwood), and Sisymbrium pannonicum 

 (Tumbling Mustard), found elsewhere along the Fylde coast, which are also 

 maintaining themselves. 2 



The Built-up Area. 



Rossall Point, and the dunes to the south as far as Rossall School, are more or 

 less free of property. The northward extension of the built-up area associated 

 with Blackpool is first met at Cleveleys, although here it does not extend far 

 inland. One-and-a-half miles down the coast is some of the most recent 

 evidence of the popularity of Blackpool for both seasonal and permanent 

 residence, and to-day, as may be seen from the map, Norbreck, Bispham, 

 Carleton (Sheet 29, B. 3), and Poulton-le-Fylde, are ever-widening groups 

 linked by long lines of houses. Blackpool stretches due east from the Central 

 Pier to Great Marton (Sheet 29, C. 3) and into the former bog land around 

 Marton Mere. Market-gardening, mainly for the provision of green vegetables 

 and spring flowers, is a big feature of this reclaimed land, and reaches south- 

 ward to Blowing Sands (Sheet 29, D. 3), where large glass-houses are common 



Blackpool is stretching southward and St. Annes eastwards, but there 

 remains a mile of untouched dune between the two, whilst between St. Annes 

 and Fairhaven, the dunes, although backed by houses, are still in evidence ; 

 Lytham has increased relatively little. At Warton (Sheet 29, E. 6), poultry 

 farming is a popular means of remuneration, and a phenomenon as catastrophic 

 for the botanist as building, apart from the interesting casuals which the 

 poultry food provides. 



Area VI. 



Grazing land in the Marton region is very wet, with poor grass, and much 

 rush and sedge. South of Inskip the moss has been converted into rich 

 arable land, which formerly supported corn. 



The region enclosed within lines drawn through Marton, Weeton (Sheet 29, 

 C. 5), Singleton (Sheet 29, B. 5), and Poulton-le-Fylde, supports the 

 following : — 



Castalia alba White Water Lily. 



Pimpinella major Greater Burnet Saxifrage.
