ADDITIONAL LOCALITIES 

 FOR THE VASCULAR PLANTS OF THE 

 WEST RIDING FLORA. 



WILLIAM WEST, F.L.S., 

 Lectitrcr in Bota7iy a7id Materia Medica at the Bradfo7-d Technical College. 



In glancing through the pages of this welcome book, it struck me 

 that several other localities for some of the more uncommon plants 

 might be cited with advantage. 



Ranunculus auricomus I- is hardly an uncommon plant. 

 I mention it simply with regard to my experience of the form 

 depauperata^ which I generally find to be almost the sole form 

 on our shady banks in the Mid-Aire district, as about Gilstead 

 and Cottingley, while the form with large petals is the one I 

 have noticed chiefly on ' barren calcareous soil,' as in Gordale. 



Ficaria verna Huds. Var. incumbens F. Schultz. ' If not a 

 hybrid with Caltha' Is it possible for a plant of the Ranunculece 

 to hybridise with one of the Helleborece % 



Meconopsis cambrica Vig. occurs between BeU Busk and Airton 

 in the Aire drainage, but within a stone's throw of a farm-house. 



Corydalis claviculata DC. is abundant west of Doncaster. 



Draba muralis L. was still frequent in Upper Wharfed ale in 1887. 



Silene noctiflora L. Several plants occurred in waste ground 

 near Frizinghall in 1886. 



Cerastium glomeratum Thuill. I have seen fine plants at 

 Bingley, and I would go beyond the author's assertion, ' not one- 

 tenth as abundant as C. triviale^ and say ' not one-hundredth.' 



Claytonia perfoliata Don. is frequent as a weed. I have it from 

 Ilkley and Bramham. 



Hypericum dubium Leers, is frequent E. of Doncaster. 



Hypericum elodes L. I have from Grassington, collected by 

 Wm. Nuttall. 



Althaea hirsuta L. This has occurred as a casual this year at 

 Frizinghall. 



Geranium sylvaticum L. Aire. In plenty a few miles N. of 



Skipton. Airton to Hanlith. 

 Euonymus europaeus L. This occurs at a good elevation at 



Hawkswick, and flowers abundantly. 

 Rhamnus catharticus L. The range of this is given up to 



750 ft.; it occurs in a well-grown condition at about 1,100 ft., 



between Malham Cove and the Tarn. 



Oct. 1888.
