BOTANICAL WALKS ROUND DERBY. 29 



Crocus [Cokhicum atitiimnale, Lin.), which grows in the Breadsall 

 meadows, the flowers of which appear in the autumn, and its 

 leaves in June. In these meadows, also, in the spring, the large 

 Bitter-cress [Cardamiue amara, Lin.) is to be found growing 

 abundantly on the banks of the Derwent. 



The banks of the Derwent below Derby are a good hunting- 

 ground for the botanist, as several good aquatic plants may be 

 found upon them. The chief of those that I found there were 

 two species of Nasturtium — N. amphibium, R. Br., the great 

 Water Radish, and N. sylvesfre, R. Br., the annual Yellow Cress, 

 both of which grow to a great size. The former of these is 

 remarkable for its small pods as compared with the size of the 

 plant, whilst the last-mentioned one may be readily distinguished 

 by its linear pods, which easily distinguish it from N.palustre, D.C., 

 with its swollen turgid pods. 



Quarndon must not be overlooked by the botanist, as several 

 good plants are to be found in its neighbourhood, such as the 

 Bird's-foot Trefoil {Ornithopus perpiisillus, Lin.) ; and in Lord 

 Scarsdale's park at Ireton, JVarcissus poeficus, Lin., a remnant of 

 former cultivation, and G'llanthus nivalis, LJn., the Snowdrop, 

 are to be found. Here, many years ago, Mr. Whittaker, of 

 Morley, found Tulipa sylvestris, Lin., the Yellow Tulip; may 

 this interesting plant be re-discovered by some member of this 

 society. 



Passing over Derby to the meadows about Normanton, we find 

 there the Green-winged Orchis {Orchis Morio, Lin.) and the 

 Meadow Saxifrage {Saxifraga graniilata, Lin.), distinguished 

 from the other saxifrages by the granules of its root, hence its 

 specific name. 



Sinfin Moor I found to be a most disappointing tract of country, 

 the only plants I noticed there being the common ones that 

 are invariably found upon cultivated land. At Swarkestone 

 Bridge, in the pools there, an abundance of aquatic plants grow, 

 such as Llelosciadum iniinJafujn, Koch ; CEnanfhe fistniosa, Liu. ; 

 and Phellandrium, Lam., tlie Horsebane ; and the Great Grass 

 ( Glycerin aquatica) ; but unfortunately I failed to find two
