SOME MORE NOTES ON DOVEDALE PLANTS. 183 



purple than I have elsewhere seen them ; but the species uot to be 

 mistaken. — V. IiUck, which occurs in some plenty on some of the 

 limestone hills of the Staffordshire side of Dovedale, seems nearly 

 or quite absent from those on the Derbyshire side. In general it 

 shows a preference for sandstone ; and the Ordnance Geological 

 Survey Surveyors report that they often obtained help in detecting 

 the boundary between the shales and the sandstone by the presence 

 of V. lutea, "a crowded belt of which, perhaps not many yards broad, 

 is often seen along the outcrop of a sandstone-bed, whilst not a 

 single plant will be found on the shales which come out on either 

 side" (Mem. of Geol. Survey N. Derbyshire, p. 4). 



Alsine tenidfuUa used to occur on one of the rocky banks near 

 the path-side in Dovedale. In the summer of 1879, however, on 

 looking for it as usual when I passed, I found that every one of the 

 plants which I had noticed not long before had been taken away by 

 some ruthless and inconsiderate plant-collector. Since that time 

 it has never reappeared. It is greatly to be wished that such 

 collectors would bear in mind that they not only deprive everyone 

 else, but themselves also, of the pleasure of gathering the plant 

 again. I am glad to say that there is another station at Brassing- 

 ton, some few miles to the east. 



Stellaria media, var. umhrosa, Opitz. Hedge-bank at Fenny 

 Bentley, and near the railway-station at Ashbourne. 



Hypericum montanum occurs, but not in great quantity. I do not 

 think I have ever seen H. humifusum on limestone, and I suspect 

 that a starved state of H. perforatum was mistaken for it in 

 Dovedale. 



The Malva growing on Thorpe Cloud is M. stjli^estris, not M. 

 rotundi folia, which seems absent from the district. 



Tilia / There are one or two scrubby bushes of either T. 

 grandifolia or intermedia — it would not be safe to say which — at an 

 elevation of over 1000 ft. on one of the cliffs of Dovedale. It is 

 difficult to suppose it other than wild. 



Euonymus europmis. Dovedale, in very small quantity, and 

 overlooked until a member of my family detected it last summer. 



Geranium smujuineum. I have seen one weakly root of this on a 

 rock north of Hartington. 



Ulex Gallii, although preferring gritstone, is not excluded from 

 parts of the limestone Ijanks. 



Sarothamnus. Wholly absent from the limestone ; appears on 

 the millstone grit at Birchover, about the curious rocks called 

 Eobin Hood's Stride, and Cratcliff Tor, 



Trifolium frayiferum. Side of the road between Fenny Bentley 

 and Tissiugton. 



Ononis arvensis. Near a quarry on Hollington End, near Thorpe, 

 and also in the Via Gellia. 



Prunus Fadus. In some quantity on a stony slope near the 

 upper end of Dovedale, and also by the brook at Fenny Bentley. 



Of Ruhi, Mr. Baker notices the absence of suberect forms from 

 the limestone. — It. fisstis, the only one of that group which I have 

 yet met with anywhere in this neighbourhood, occurs on the New
