Text-fig. 1. Map of part of Hindhead Common at present surveyed. 
Pathways indicated thus = : = :=, clearings indicated thus == =*. The 
contours are indicated by heavy lines, and have been transferred from the 
Ordnance Survey maps. Areas of the common recently burnt are closely 
shaded. The black patches mark the positions of more or less extensive 
groups of Ulex europmis. The unshaded areas on the eastern slope of the 
central ridge represent exposed tracts of gravel (cf. Text-fig. 2). C U, Calluna- 
Ultx facies (cf. p. 153); CUE, Calluna-Ulex-Erica facies (cf. p. 154): Pt., 
Pteridium aquilimm. The thin irregular line running almost vertically through 
the area burnt in 1911 marks the former limit of the C U and CUE facies in 
this region. 
The distribution of Ulex minor Roth (= U. nanus Forster) is 
very different from that of U. enropceus. Together with Calluna, it 
is the dominant feature of the vegetation over the greater part of
