DISTRICT II 



This consists of the Bunter or lower division of the Trias, and includes the fine-grained 

 red or variegated sands of the Lower Red and Mottled Sandstone, and the yellow or brownish 

 sands and conglomerates of the Bunter Pebble-beds. 



The district possesses a distinctive and characteristic flora, although, as will be seen from 

 the list given below, only a few species are confined to it. This is due to the fact that most 

 sand-loving plants find an equally suitable habitat in the sandy patches which occasionally 

 occur in the Keuper Marl, in the tracts of sandy alluvium bordering the Trent in Division III, 

 and in the drift sands which cover a part of District IV on the eastern edge of the county. 



The existing remains of the once far more extensive Sherwood Forest lie entirely in this 

 district, and consist chiefly of oak and birch timber with a dense undergrowth of bracken, and 

 open spaces covered with ling (Calluna), heath (Erica cinerea), bracken (Pteris), Deschampsia 

 fkxuosa, etc., and dotted with old thorn trees much infested with mistletoe. 



A few bits of boggy ground are still to be found along the course of some of the streams, 

 as at Oxton and Rainworth, and to these we owe the survival of some of our most interesting 

 plants. Of late years, however, owing partly to a succession of dry seasons and partly to the 

 sinking of deep wells for the water supply of the surrounding towns, these bogs have become 

 nearly dry at times, with the result that such things as the sundew (Drosera), butterwort 

 (Pinguicula), cranberry (Schollera Oxycoccus), marsh fern (Lastrea Thelypteris), etc., are fast dis- 

 appearing or have already gone.

The Keuper deposits which underlie this extensive district are separable into two 

 divisions. The lower of these, known as the ' Waterstones,' consists of alternations of dull
