202 SOME MORE NOTES ON DOVEDALE PLANTS. 



exhibit its form. Mr. Baker tells me that he has met with a 

 limestone Epipactis in the Lake district, which he at first thought 

 might be oralis, but which he afterwards decided to be latifolia. It 

 seems likely to be identical with the Herefordshire plant. 



Paris (juadrifolia. Dovedale, but scarce. 



Poh/(/()iiatum officmale. Dovedale. 



Allium 2irsinu)ii. Abundant in one part of Dovedale. — A. 

 oleraceAim. I had the pleasure of meeting with tiais, last August, in 

 the clefts of one of the Dovedale rocks, about 1100 ft. I think not 

 previously recorded from the county. 



Scirjius setaceus. Dovedale. — S. sylvaticus. By the Dove, above 

 Hartington. 



Carex muricata. Between Hartington and Beresford Dale. — 

 C. vulpina. Between Sandy Brook and Eose Cottage, near Ash- 

 bourne. — C. riparia. Near Bradbourne Mill. — C. paludosa. Banks 

 of the Bradford, at Youlgrave. 



Avena puhescens is abundant in limestone pastures. — A. pratensis. 

 Very much less common. 



The Ghjceria which is so abundant in the lower reaches of 

 Dovedale is G. pediceUata. — There are two forms of (x. plicata ; 

 one, which I suppose to be the typical plant of Fries, is glaucous, 

 with blunt broad leaves, which are folded in vernation ; the other, 

 a much taller plant, quite green, like G.Jluitans, and with narrow- 

 pointed simply-folded leaves, and with a much larger panicle ; 

 both of these, as well as G. pediceUata, were observed by Mr. C. 

 Bailey and myself about the upper Eeservoirs of the Via Gellia. 

 These forms seem to have received little notice from botanists, but 

 their diiferences are obvious if a little attention is given to them. 

 Of G. pediceUata the fruit seems invariably abortive, if not infested 

 with ergot, to which it is peculiarly liable. I observe that Mr. 

 Townsend in his original description gave no account of the cary- 

 opsis, probably never having seen it. 



Festnca. There is in Dovedale and various other places a very 

 glaucous form, which I presume to be that intended under the 

 name of F. ovina, var. (jlauca, of the ' Student's Flora.' — F. elatior. 

 Dovedale and elsewhere ; especially plentiful in the Via Gellia ; 

 when in flower its divaricate panicle-branches make it conspicuous. 



The absence of Bromiis ercctus has always struck me as remark- 

 able ; I see, however, that Mr. Painter records it from Miller's Dale. 



The Ferns of the district have grievously suffered from the 

 ravages of the guides. — Ceterach officinarum, which, I am credibly 

 informed, was formerly abundant on the rocks of Dovedale, is 

 almost absolutely extinct. I have this day, after a careful search, 

 succeeded in finding a single small plant (which I of course left 

 undisturbed) in a place which had been mentioned to me, but 

 I know not where I could find another on the Derbyshire side. 



Pob/podium U«hertianum is no longer to be found on the Derby- 

 shire side of Dovedale. The extremely dry summers of 18G8-1870 

 seem to have destroyed it ; the spot on which I am told that it grew 

 i)lentifully is much exposed. I have seen it, but in very small 

 quantity, on the Staffordshire side.
