SOME MORE NOTES ON DOVEDALE PLANTS. 

 By the Rev. W. H. Purchas. 



(Concluded from p. 184). 



Pyrns nipicola. Mr. Baker did not see this on the Derbyshire 

 side of Dovedale ; had time allowed him to penetrate farther up the 

 Dale he would have fallen in with numerous small trees of it. 

 Many of them grow in maccessible situations, but all which I have 

 been able to examine belong to P. rupicola. — True P. Aria exists, 

 as Mr. Painter stated on my authority, as a single tree at the edge 

 of a plantation near the fifth milestone on the road from Ashbourne 

 to Buxton, but it has the appearance of having been planted ; the 

 tree is an old one, and flowers freely, but there are no traces of 

 young seedlings. 



Epilobiniii rosew)! occurs sparingly at Fenny Bentley. The late 

 Rev. G. E. Smith told me also that it grew near Osmaston, by 

 Ashbourne, but it is a scarce plant in the district. — E. ohacurum 

 occurs also at Fenny Bentley, in company with E. montanum. 

 Some few specimens growing with E. montanum and E. obscuriim at 

 Fenny Bentley have much the appearance of being hybrid between 

 these two, although chiefly akin to E. montanum. I have also 

 found on the hanks of the Dove a form having characters inter- 

 mediate between E. parcijiorum and E. obscimnn. Specimens of 

 this were lately sent to the Botanical Exchange Club with other 

 intermediates between these two species from this part of Stafford- 

 shire. — E. palustre, which is common in the Staffordshire moor- 

 lands, seems wholly to avoid the limestone. 



Mi/rinpJn/lhim sjiicatum. Li the Reservoirs at Cromford, where 

 my attention was called to it last year by Mr. C. Bailey.
