38 BOTANICAL NOTES FROM BUXTON TO MILLER'S DALE. 



visits to this dalei And here, in August, is to be found one of the 

 rarest Derbyshire plants, growing upon a perpendicular rock, 

 Hieraciuin prenanthoides ( VilL), a specimen of which is included 

 with the plants now exhibited. 



Lower down the Dale several bushes of Salix Caprea [Linn ) (the 

 Great Sallow) were noticed ; in the swampy ground Carex rostrata 

 [Stokes) was found ; whilst in the plantations Foa nevwralis [/.inn.], 

 var. angustifo/iu (Farnell) was gathered, a grass which, on being 

 submitted to Mr. C. Bailey, F.L.S., for his verification, was pro- 

 nounced by him to be the above-mentioned variety. 



On a level piece of wet ground in this Dale is to be found 

 another rare plant, Scirpits Carta's {Retz), which flowers in July 

 and August. This is its only habitat in Derbyshire, and thus in 

 this dale two plants are found which do not occur elsewhere in 

 the county. 



Hastening on our way through Miller's Dale, in which during 

 the season several roses are to be met with, we notice here and 

 ihere small plants of Geranium cohanbinum iLitm.), or the long- 

 stalked Crane's-bill, a plant which is generally found on lime- 

 stone banks; Arenaiia serpyllifvlia {Linn.), a tolerably common 

 plant ; Popniiis canescens (Sni.), a tree which grows at the beginning 

 of the Dale, but is mentioned iiere because of its place in the 

 Botanical order of plants ; and last, but not least, Sa/i.x iindtilata 

 {Ehrliardt), a willow upon which 1 have some lengthy remarks to 

 mnke. 



When I first saw this tree in August, 1883, unlike other willows, 

 it had produced summer catkins, which are more or less pubescent, 

 a fact which had misled many Botanists. Upon specimens of it 

 being submitted to our greatest British authority upon the willows, 

 Dr. J. Buchanan White, of Perth, he requested me to visit this 

 tree in June and obtain the spring capsules. 'I'hese turned out 

 to be quite glabrous. Thus Dr. White was enabled to determine 

 the species of this willow, and also to settle the question of its 

 parentage, for this willow is a hybrid of two other willows, and not 

 a true species. To quote Dr. White's own words, given in my 

 " Flora of Derbyshire " : " The great interest," he sa)S, " attaching
