of Austria and Russia. The American S. opulifolia occurs, or 

 has occurred, under similar circumstances in a wood at Easby 

 near Richmond ; James Ward ! 



Dryas octopetala L. Highland type. Native. Montane. 

 Subxerophilous. Area 9. Range 600. With Helianthemutn 

 caelum upon the Sugar Limestone of Cronkley Fell, 



Geum urbanum L. British type. Native. Area general. 

 Range 0-350. Frequent in woods and upon hedge-banks 

 throughout the lower zone, ascending to the foot of Widdale 

 and the Swale side west of Keld. 



Geum rivale L. British type. Native. Area general. 

 Range 0-800. Frequent in damp and shaded places, ascending 

 to the Main Limestone of Mickle Fell. G. intermedium Ehrh., 

 which is frequent in woods, appears to be a hybrid between this 

 and the preceding. 



Agrimonia Eupatoria L. British type. Native. Area 

 general. Range 0-400. Frequent in grassy places, ascending 

 in Swaledale to the Main Limestone Scars of West Stonesdale 

 Moor. 



Agrimonia odorata Mill. On the slope of Penhill above 

 West Burton, and in Bishopdale west of Thoralby ; J. Percival. 

 Hedge-bank near Codi)eck between Sowerby and Dalton. 



Potentilla fruticosa L. Intermediate type. Native. 

 Montane. Area 9. Range 250-400. This species in Upper 

 Tecsdalc is one of the most prominent plants of the river-side. 

 It begins at Upper C!ronkley, is plentiful al)out the Fligh Force 

 and Winch Bridge, and continues down the river as far as the 

 Middleton Bridge. It is given by Ray as a plant of the Tees 

 side near Egglestone Abbey, but I have not seen it there, and 

 probably it was only ca.sually washed down. Its abundance in 

 Tecsdalc, considered in connection with its rarity in the rest of 

 Britain, is one of the most salient facts of plant-topography 

 which it falls within the scope of these notes to register. 



Potentilla anserina L. British type. Native. Area 

 general. Range 0-350. Frequent along road-sides and in
