200 SOME MORE NOTES ON DOVEDALE PLANTS. 



Lysimachia nemomm. Scarce iu N. Derbyshire, and only seen 

 by me sparingly in the upper part of the Dove Valley. 



l'oli/i/(inu'm JJifitortd. Fenny Bentley. 



Daji/inc Mezereum exists, although in very small quantity, on the 

 Derbyshire side of the Dove Valley. 



Popuhis tremula would have been seen by Mr. Baker had 

 time allowed him to explore the upper part of Dovedale. It grows 

 about the rocks in which are the caverns called the Doveholes, but 

 in small quantity. 



Salices are fewer in N. Derbyshire than even in N. Staffordshire. 

 — S. vimmalis, alba, cincrea, and Caprca occur in the upper reaches 

 of Dovedale. Near Lode Mill, and again farther down the stream 

 are some small trees of S. Forln/ana (identified with very little doubt 

 by the Kev. J. E. Leefe). The head-quarters, however, of this 

 species are on the Staffordshire bank of the Dove, just below 

 Lode Mill, where there are several old trees about 15 ft. high, 

 and I suspect that the younger bushes have been derived from 

 these through branches which have been torn off" by winds or 

 floods having been carried down and lodged on the banks, there 

 taking root and growing. In other cases I think they must have 

 been planted as cuttings : all are the female plant, I find this 

 to be one of the willows most frequently planted near houses 

 and gardens hereabout, I suppose for the sake of a supply of 

 twigs. — S. Janceolata Sm. A willow found in Miller's Dale is 

 thus named by the Eev. J. E. Leefe. So far as can be decided 

 without comparison of the catkins (for Mr. M. Kay's specimen is 

 without them), this is exactly the same as the plant from Cambus- 

 lang, Lanarkshire, distributed by the Botanical Exchange Club 

 under the name of undulata. The Derbyshire plant was met with 

 late in August, where it was flowering a second time, just as the 

 Triandrcc, and more frequently S. hippophafffolia, will do. It is 

 the pistillate plant (Has the staminate plant been yet found in 

 Britain?), and has the appearance of being native on the river-bank. 



Taxus haccata. Plentiful on some of the cliffs of Dovedale. 



Of Potamogetons, P. crispus is the only species I have been able 

 to find in the Dove. — P. nutans. In a pond near the Ashbourne 

 and Buxton Eoad, four miles from Ashbourne. — i'. ziMcrafolim. 

 In the Cromford Canal, and in Keservoirs at Cromford, where my 

 attention was called to it last summer by Mr. C. Bailey. 



Orchids are less plentiful than might have been expected.— 

 Orchis pijramidaUs. On the slopes of the Via Gellia. I have not 

 met with it in Dovedale. - — 0. masciila and maculata are common. 



Gij)iniad('nia conopsca. In the Via Gellia, sometimes with white 

 flowers. Although occurring plentifully in one of the Staffordshire 

 valleys a few miles west of Dovedale, I have not seen it between 

 that Staffordshire habitat and the Via Gellia, a distance of eight or 

 nine miles. 



Hahcnaria Hridis, Pastures near Hipley Tollbar, on the road 

 between Parwick and Brassington, — H. cJdorantha. Dovedale, 

 and between Thorpe and Mappleton, but capricious in appearing. — 

 H, hifulia I have not seen on the Derbyshire side, although it
