The high range of hills called the Yorkshire Wolds, 
beginning at the coast near Bridlington, is composed of 
chalk. This formation extends by Driffield, forming a bow 
betwixt Beverley and Pocklington to the Humber. In this 
part the Ericag are not found. The only rare plants are a 
few common to limestone, viz. Festuca pumilis, bromoides, 
Oentiana amarella yS, Chlora perfoliata. Astragalus hypo- 
glottis. Passing the Vale of Pickering (lately rendered 
notorious by the fossil bones discovered in the Kirkdale 
jCave), we come to the Oolite, extending from Scarborough, 
by Kirkby Moorside, Hemsley, to meet the Alluvium near 
Easingwold ; it then takes a turn to the east, and passes 
Malton, and we find on it the following plants : Chara his- 
pida, flexilis, Veronica montana, Utricularia minor, Schae- 
nus mariscus, albus, Scirpus pauciflorus, acicularis, sylva- 
ticus, Bromus pinnatus, Arundo epigejos, calamagrostis, 
Lolium arvense, Elymus europaeus, Galium tricorne, Pota- 
imogeton gramineum, Viola hirta, lutea, Gentiana pneumo- 
nanthe, Bupleurum rotundifolium, Caucahs daucoides, 
Pimpinella magna, Linum perenne, Drosera Anglica, lon= 
gifolia, Paris quadrifolia, Pyrola rotundifolia, Potentilla 
verna, Geum rivale, Papaver hybridum, Ranunculus lin- 
gua, parviflorus, &c. 
The only district which I have not been able to examine 
is the Alum-shale, rising on the coast, from Whitby to the 
Tees, including the Vale of Esk. The small line of Basalt 
found in Yorkshire, passes through the above.
