THE BOTANY OF BIDDULPH.

Rudyerd Basin .—The geology of this district is more 
diversified than is that of the others. On Biddulpli Moor a 
small patch of Yoredale rocks occurs ; at Rusliton Spencer 
the Permian rocks crop out; and at Rudyerd Reservoir a 
large piece of Alluvial is to be found, but all the high ground 
is composed of Millstone Grit. 
The whole of these districts was, until the Enclosure Acts 
were passed, a large tract of moorland. The result is, that 
here and there patches of ground are to be found representing 
the former state of the land, upon which plants now grow 
representing a moorland flora. 
The altitudes from which I have worked, taken from the 
Ordnance Survey maps, 6in. scale, are as follows :— 
Biddulpli Church. 515 feet. 
Troughstone Hill.1,017 ,, 
Biddulpli Park. 786 ,, 
Methodist Chapel, ditto. 960 ,, 
Wickenstone Rocks. 857 ,, 
Lask Edge, summit.1,100 ,, 
Rushton Dingle. 625 ,, 
Rudyerd Reservoir I found to be 600ft. above the sea-level by 
aneroid, and the altitudes which are given in the following 
pages have been obtained, for the most part, by actual 
measurement from the above bases. 
Thus it will be seen that this part of Staffordshire lies in 
the mid-agrarian zone of Mr. H. C. Watson, and is 
characterised by the presence of such plants as Uiex Gallii, 
Viburnum Lantana, and Calystegia Sepium.

The total number of plants mentioned in the following 
pages, omitting those which are known to have been planted 
within the memory of man, is 389 ; thus there is a dis¬ 
crepancy between the number of plants seen, and those 
tabulated above ; a fact which is partly accounted for by the 
arrangement of the Rubi in the London Catalogue, Ed. 8, 
which has been followed as regards the nomenclature and 
the species enumerated, differing from that of Mr. Watson’s 
“ Compendium.”
