phoriim moor, Racomitriiim moor, Scirpus moor, Calluna, Vaccinitnn, 

 /uncus. The Calluna association Covers the lurgest surface and occurs 

 on peat which is well drained ; on steep rocky slopes this gives way to 

 Vaccitniiin, while in places supplied with water from Springs the Junciis 

 association forms islands in the Calluna, The „black bog" or water- 

 logged peat at higher elevations is occupied by Scirpus and Erio- 

 phoruni moor, The Racomitrimn moor is a siimmit Vegetation which 

 occupies very broken ground made up of higher bosses of peat with 

 much water in the hollows between ; the Vegetation includes much Cal- 

 luna, Erica tetralix, Scirpus caespitosus and Eriophorum spp.^ but over all 

 there is an abundance of Racomitriuni lanuginosum, which is used to 

 designate the association. The Hill Pasture zone is represented by 

 four colours on the map: Pteris association, Ulex associations (2 colours) 

 and Nardus heath. The Nardus Grass Heath is very limited in com- 

 parison to other areas mapped in Britain, and almost all the hill 

 pasture zone is made up of the other associations. Pteris aquilina and 

 its associates occur on deep well-drained soil, and the association is 

 intrusive into the Ulex and the Calluna. It is noted that on undulating 

 ground Calluna frequently occupies the slopes exposed to the prevailing 

 westerly winds, where as Pteris is dominant on the sheltered slopes with 

 an eastern exposure. Two distinct zones of Ulex are recorded on the 

 map: Ulex gallii in the higher hill pasture zone, and U. europaeus at lower 

 elevations in the agrarian zone. The association of U. galli consists of plants 

 which are smaller in size and more xerophytic than those found with U. euro- 

 paeus. Forest is poorly represented in the area ; Oak (Quercus Robur) 

 appears to have formed forests in tlie Valleys, being replaced at higher 

 altitudes by Birch {Betula) scrub, which is found as remains in the 

 peat up to 520 metres ; Scots Pine {Pinus sylvestris) is now present 

 in plantations on the margin of the Calluna moorland, but remains occur 

 in the peat up to 380 metres. 



The associations, only briefly referred to here, are described in 

 detail and füll lists of associate plants are given ; the features are illu- 

 strated by a good series of photographs. The map printed by the Ord- 

 nance Survey Department is an cxcellent production; the scale is 

 1 : 63 360. W G. Smith (Leeds).
