198 SOME MORE NOTES ON DOVEDALE PLANTS. 



Taraxacum officinale, var. pahistre, occurs in a swampy part of 

 Dovedale. 



Crepis paludosa. Near the source of the Dove, and I think on 

 the Derbyshire side of the stream, but ceasing when the hmestone 

 is reached. 



Uieracmm. Mr. Baker remarks on the absence of H. murornm 

 and H. ca'sium. The plant, however, which Mr. Baker regards as 

 H. caimim, var. Smithii, occurs on the rocks of Dovedale, ascending 

 to nearly 1100 ft, and has been recorded by Mr. Painter. I first 

 met with this, some twenty years ago, on the rocks of Middleton 

 Dale. Mr. Baker, to whom I lately sent some Dovedale specimens, 

 considers it identical with the plant of the limestone rocks of York- 

 shire, and to be truly H. ccedum, var. Smithii. Dr. Boswell, on the 

 other hand, as confidently refers it to H. pallidum. Between these 

 opinions it is not for me to attempt to decide. I will only say that 

 the Derbyshire (and Staffordshire) plant is very glaucous, and that 

 the leaves are much more suddenly narrowed at the base than in 

 Dr. Boswell's Fifeshire H. p(dlidum; and with radiating teeth, 

 which, as in that, are often half an inch long. On the other hand, 

 the Derbyshire plant differs notably from a Herefordshire plant 

 which I have known for many years, and of which examples 

 pronounced by Mr. Baker to be iJ. c^sMtm were sent to the Botanical 

 Exchange Club by the Eev. A. Ley (see Eeport for 1882). The 

 leaves of this plant from the limestone rocks of the Herefordshire 

 Wye Valley are broader in outline than those of the Derbyshire 

 plant, and, instead of long radiating teeth, have scarcely more than 

 denticulations on their margin ; the Derbyshire plant also wants 

 the reddish purple so noticeable on the under surface of the leaves 

 of the Herefordshire " H. ccBsium.'' I have met with this Derbyshire 

 HieraciuDi. at Linton, N. Devon, and on rocks near Tenby, from 

 which latter place it was recorded by Mr. E. Lees in the 'Phytolo- 

 gist,' 0. S., 1853, p. 1018. It is a form which departs from 

 H. murorum rather in the direction of H. amjlicum than of H. 

 sylvaticum.. — True H. murorum, seems to be very rare in Derbyshire ; 

 I have, however, met with it well marked between Miller's Dale 

 and Cressbrook, as also in Ashwood Dale, Buxton, but in small 

 quantity only. I have cultivated this Ashwood Dale plant for 

 several seasons side by side with the green typical H. viurornm from 

 the woods of Herefordshire, and I can see no farther difference than 

 that the Ashwood Dale plant has just a slight tendency to be 

 glaucous. — The form of H. vuhjatum, which Dr. Boswell has distri- 

 buted under the name of "/i. rusulatum" from Fifeshire, occurs 

 with the type on the rocks of the Dove Valley. — H. umhellatum. 

 On the Yoredale Eocks of the upper part of the Dove Valley, 

 I think on both the Derbyshire and tStaflbrdshire sides of the 

 stream, which is there very narrow, but ceasing when the limestone 

 is reached. 



Jasione montana, like the last, occurs freely on the Yoredale 

 Eocks of the upper part of the course of the Dove ; but I have 

 never seen it on the limestone, and I think there must be some 

 mistake as to its having been met with in Dovedale. On the 

 millstone grit at Eobin Hood's Stride, near Birchover.
