BOTANICAL NOTES FROM BUXTON TO MILLERS DALE. 35 



in various parts of the county. When looking over broken 

 ground near the Lover's Leap, my attention was attracted to a 

 tall cruciferous plant, which I immediately discovered to be 

 Draba t/iuralis {Linn.), one of the Whitlow grasses, a plant which 

 grows only upon the mountain limestone, and which I have also 

 gathered at its most southern habitat, Stone Eaton, in Somerset- 

 shire. Close to it was the little Hutchiusia petrcea {/?. Ba.), a 

 plant which is plentiful in the limestone dales, and one which I 

 once travelled thirteen miles in a gig to find. In company with 

 these was the little Alchemilla arvensis, {Lam.), or Parsley Picrt, a 

 plant which is not of frequent occurrence in Derbyshire, and also 

 Valerianella olitora {Moetich), or Lamb's Lettuce, another plant 

 which is not frequently met with in the county, especially in the 

 hilly parts. 



Close to these, but hidden away in the grass, grows Saxifraga 

 Genin {Lhm.), or London Pride, which has been growing here for 

 many years, and has thus become naturalized. On the rocks 

 above the spot where this plant grows is to be seen early in July 

 the beautiful Polemonium coenihim {Linn.), the Blue Jacob's 

 Ladder, a plant which extends southwards from the limestone 

 dales of Yorkshire, and which is found only in a wild state in 

 similar dales in Derbyshire, though it is frequently found as a 

 garden escape. Specimens of these two plants are exhibited, 

 though they were not gathered in the course of this excursion. 



The next plant of which a specimen is exhibited is Cardamine 

 Hexuosa { Willi.), which is said to be considered a variety of 

 Cardamine hirsuta {Linti.), but it will be seen that it is a well- 

 marked species, easily distinguished by its fiexuous stem and 

 spreading fruit pods. This plant abounds all through the dales 

 in the gutters by the sides of the roads. 



The sides of the river Wye all down this dale are fringed with 

 several species of willows, such as Sa/ix fragilis {Linn.), var. 

 Britannica of Dr. F. Buchanan White, which prevails through- 

 out Britain, the true Salix fragilis not being known in Great 

 Britain; and Salix viminalis {Linn.), easily distinguished by its 

 long and narrow leaves.
