Area III. 



A small tract of country along the river Cocker below Cockerham is worthy 

 of some mention. It consists of low, flat alluvium drained by ditches, and 

 yields the following : — 



Ranunculus Baudotii 

 OEnanthe fistulosa 

 Bidens cernua .... 

 Hottonia palustris 

 Samolus Valerandi 

 Callitriche autumnalis .... 

 Hydrocharis morsus-Ranae

Slender Sand Sedge. 



Clean-cut ditches along the Cocker below Cockerham are rapidly clothed 

 with lichens, whilst the surface of the water soon becomes a mass of algal 

 filaments. Algae are very common throughout the sluggish Fylde ditches, 

 and benefit by the drainage of the heavily-manured fields. Potamogeton 

 natans (Broad Pondweed) is common throughout the Fylde ditches and 

 numerous ponds.
