6 BOTANICAL WALKS ROUND DERBY. 



if the plants that I had gathered there in previous years were still 

 living in the old habitats, and this I found to be the case. 

 But besides finding these I lighted upon some that had not been 

 recorded as growing in this part of Derbyshire, such as Ranunculus 

 fiuitans {Linn.), Rosa fonieiitosa (Sni.), with itshairy and compound- 

 serrate leaflets, the Black Poplar, Popubis nigra [Linn.), Trisetum 

 flavescens {Benin'), evidently here a cultivated grass, Catabrosa 

 aquatica {Beam.!), which I found in a ditch, all of which I met 

 with at Swarkestone, Then between Chellaston and Swarkestone, 

 or at Chellaston, I noticed the following : the Common Water- 

 cress, Nasturtium officinale {R. Br.), the Creeping Scorpion Grass, 

 Myosotis repens {D. Don.), and the Water Knotwort, Sciophularia 

 aquatica [Linn.), Hordeum pratense {Huds.), a grass that I had 

 not previously gathered in the county, Leontodon hirtiis {Linn.), 

 another plant not previously seen by me in these parts, the Lamb's 

 Tongue, Plantago media {Linn?), a common plant in the Limestone 

 Districts, as is also Picris hiiracioides {Linn.), the Hawkweed- 

 picris. Passing over Swarkestone Bridge, at Stanton I came upon 

 a Bramble, near an old quarry, which I was much delighted to 

 meet with, Rubus thyrsoideus { Winini), the discovery of which, 

 both here and at Repton, enabled the Rev. W. Moyle Rogers, 

 our present authority upon this genus, to settle the point whether 

 this plant was growing in Derbyshire. The white felt underneath 

 the leaves, and the irregular and jagged serration of the margin of 

 the leaves should be noticed. R. rusticanus {Merc), a Bramble 

 related to the one just mentioned, was also abundant here. Then 

 in a small pool of water here I met with a Duckweed, Lemna 

 trisuka {Linn.), which I had not before seen in Derbyshire, and 

 upon a wall, Poa compressa {Linn.). 



Keeping on this side of Derby, Willington and Repton are the 

 next places that I would take you to. The canal bank at the first 

 mentioned place is good hunting ground. Here I found the 

 Zig-zag Clover, Trifolium medium {Linn.), with its large heads, 

 Lindley's Bramble, Rubus Lindleyanus {Lees), which is dis- 

 tinguishable by its polished stem, the Marsh Bed-straw, Galium 

 palustre {Linn.), var. WitJieringii {Smith), the prevailing variety
