 be expected to occur: —

 Anthoxanthum odoratum

(4) Places where acidic humus is present in good 

 quantity. The oak remains dominant: the birch and the 

 mountain ash are often abundant : the wych elm and the 

 ash are rare or absent : shrubs are rather rare and sometimes 

 almost absent ; whilst heathy dwarf shrubs, especially the 

 bilberry, are typically abundant (see figures 3 and 7). Ground 

 species with showy flowers are rare : the soft-grass {Holcus 

 mollis) is local and often absent ; but the silver hair-grass {Des- 

 champsia flexuosa) becomes exceedingly abundant : the bracken 

 varies from being very abundant to very rare. This type of 

 vegetation was termed by Woodhead (1906: 347) a "xero- 

 Pteridetum," It is characterized by the following species : — 



Nephrodium dilatatum 

 Blechnum spicant 

 Pteris aquilina 

 Potentilla erecta 

 Ulex Gallii (local) 

 Cytisus scoparius (local) 

 Lathyrus montanus 

 Polygala serpyllacea 

 Pyrola media (v. rare) 

 P. minor (rare) 

 Calluna vulgaris 

 Vaccinium Myrtillus 

 V. Vitis-idaea (local) 

 Teucrium Scorodonia 



Digitalis purpurea 

 Melampyrum pratense 

 var. montanum 

 var. hians

The two last-mentioned types of ground vegetation occupy 

 by far the major portion of the woodland area, and they have
