204 NEW LOCALITIES FOR RARE WARWICKSHIRE PLANTS. 
As to the origin of the little nodules, I believe that they are 
little pebbles, so to speak, of the same finer ash as the matrix in 
which they lie, flattened and squeezed at the edges by the general 
regional pressures of the district. 
The fragments of slate in the coarser and more unmistakable 
ash are very similar to those which occur in the ashes of Cader, as 
mentioned by Messrs. Cole and Jennings in their paper on that 
mountain (Q.J.G.S., 45, p. 422). 
Since the meeting of the Union at Birmingham, Mr. Nicholson, 
of Oswestry, has kindly sent me another specimen of this curious 
nodular rock, from which I have been able to make sections. 
These tend to confirm the opinion expressed above that the rock is 
really a very fine ash. In this specimen there is no evidence, so 
far as I can see, of the finer structure round the edges of the 
nodules; between crossed nicols the nodules disappear utterly. 
Using ordinary light, however, there is a distinctly concentric 
structure visible in some of them. Mr. Nicholson informs me that 
the nodular rock occurs as a band about 18in. thick near the 
middle of the ash beds. 
NEW LOCALITIES FOB BABE WABWICKSHIBE PLANTS. 
I have lately received from valued correspondents records of 
new localities for several rare or local plants, and as most of these 
are too late for insertion in their proper sequence in “Notes on 
the Flora of Warwickshire ” now appearing in the “Midland 
Naturalist,” I think it will be better to give the new matter as a 
separate article. 
From Miss Sawyer, to whom I have already been indebted for 
kind help, I have received a specimen of the rare Verbascum virgatum, 
found near Haseley Hall. This is a rare alien of the Atlantic 
English type, and has only been recorded from one other Warwick¬ 
shire station. 
My friend, Mr. H. Stuart Thompson, sends me several records 
from the Blythe district, amongst others Dipsacus pilosus (the 
Shepherd’s Bod), in abundance in a lane near Mercote Hall!
