Lying over the limestone shale on the east and north is the mill- 

 stone grit, consisting mostly of massive coarse hard sandstones, which, 

 owing to the underlying shales having been much worn away, present 

 valleys running north and south, topped by lofty escarpments of grit on 

 their eastern side. The grit forms the extensive high tableland of the Peak 

 and Axe Edge, and extends southwards on both sides of the Derwent 

 valley to Little Eaton near Derby. This with the adjoining shales is 

 divided into two by a line drawn east and west through Hathersage, the 

 northern portion forming division II., the southern division III. of the 

 flora. There is one outlier of the grit in the south of the county about 

 Stanton and Melbourne. The following is a list of plants characteristic 

 of the grit moorland, those peculiar to it being marked with an asterisk :

Next above the grit come the coal measures. The lower beds form 



a strip of varying width on the true coal measures. They consist of 



varied sandstones, shales, fireclays and a few thin coal seams, and are 



succeeded on the east by the middle and upper coal measures, extending
