66 YORKSHIRE NATURALISTS’ UNION AT POCKLINGTON. 
a lane between Pocklington and Allerthorpe Common, Prunus — 
communis and its variety P. insititia, were noticed (and the fruit 
artaken of). Further on, near an old manure-heap, were gathered 
Melilotus parviflorus, Chenopodium rubrum, and C. album var. 
viride. Proceeding nearer to the Common, the hedge-banks yielded 
following were added to the list :—Genista anglica, Cnicus pratensis, 
Lieracium umbellatum, Parnassia palustris, Erica cinerea, Salix 
repens var. argentea, Carex stellulata, Lastrea dilatata and a few 
belated Gentiana pneumonanthe. The dry weather was responsible for 
the total absence of such water-loving plants as ait: rotundifolia. 
The disused canal was well searched and one member was well 
rewarded by the discovery of Ceratophyllum p Bide probably 
a new record for the East Riding. The cellular cryptogams 
were very interesting, though not many oo Dicranella 
haart Dicranum spurium, Campylopus pyri, ts, C. fragilts, 
C. flexuosus, Bryum erythrocarpum, Plagiothecium steers and 
A mibweree riparium. ‘The rare hepatic, Fossombronia dumortiert, 
found by the late Dr. Spruce in 1842 on the same ground, was also 
found by Mr. Marshall. It may be mentioned here that in the 
circular issued before the meeting Carduus heterophyllus was stated 
to have been found. This should read Carduus pratensis. 
For the Geological Section, Mr. J. W. Stather, F.G.S., gives the 
following report :— 
Looking at the. Geological map, the town of Pocklington, 
situated as it is on the Keuper Marls, just outside the western 
fringe of the chalk wolds, with the Lower Lias intervening, appears, 
and actually is, an excellent centre for geological research. But it 
must be confessed that our geological party, chiefly through the 
want of a local guide, were able to do but scant justice to the 
district. 
As suggested in the printed programme, the geologists assembled 
at Nunburnholme Station, and during the pleasant walk between 
that place and Wartar Priory, caught good views of the escarpment 
of the Wolds to the east, but did not see any open sections. Near 
the village of Wartar the famous brickfield mentioned by Tate and 
Blake was visited, and although much overgrown and obscured by 
sliks, proved a most interesting section. 
Here the red chalk was seen to rest directly on the Lower Lias, 
a fact which bears eloquent witness to the amount of denudation 
accomplished in this area during the secondary period. Here also 
a few common Lower Lias fossils were obtained, and Professor 
Naturalist.
