330 SOUTH DERBYSHIRE PLANTS. 



Shirley this summer. Primula vulgaris Huds., var. caulescens Bab., 



as well as P. veris x vulgaris^ are found sparingly in the spring. 



Cuscuta Trifolii Bab. has been seen on cultivated land in Bradley. 



Mentha viridis L. and M. rubra Sm. occur by Shirley Brook, and 



M. Piperita Huds. at Yeaveley, the first and the last being not 



indigenous. Betula glutinosa Fr. is to be seen not unfrequently in 

 hedges. 



Salices of the Smithiana group are found in several places, some 



agreeing more closely with S. Smithiana Willd. proper, others 



coinciding with S. rugosa Leefe. In them the foliage varies very 



little, the main differences being exhibited by the stigmas, which 



are linear and long, or oval and shorter, entire bifid or bipartite in 



different plants examined. S. repens L. though not observed in the 



district, has been seen by me further south in the county, by the 



road-side near Etwall. The usual form of Populus tremula L. which 



occurs about here is the var. glabra Syme ; and Iris Pseudacorus L. 



only occurs as acoriformis Bor. Juncus diffusus Hoppe has not been 



noticed, I believe, in many places in the county, and has only been 



recently added to the county Flora; I have seen it in Shirley 



growing plentifully, and still more abundantly some few miles to 



the north, near Corley. In both cases it appears to be a species, 



as described in Bab. Man., rather than a hybrid, as described in 



Hooker's ' Students 1 Flora/ J. tupinus Moench, var. Kochii Syme, 



I have seen in Shirley Wood. Potamogeton serratus Huds. is the 



common form which P. crispus takes in brooks and streams in the 

 district. 



Carex curta Good, is to be found, but not plentifully, in a marsh 

 m Yeldersley. One patch of 0. Goodenowii J. Gay, v&v.juncella Fr., 

 occurs in Shirley Wood. C. prcecox Jacq. almost covered the 

 ground in several fields, in 1887, in Shirley; this year I have seen 

 no trace of it. C.fulva Good., I believe the type, is found in one 

 meadow in Shirley. C. paludosa Good, very frequently takes the 

 form Kochiana Gaud. 



Among grasses, I have seen the form Arrhenatherum nodosum 

 Bchb., and Bromus arvensis L. as a casual by the road-side. Ayro- 

 pyron repens Beauv. frequently occurs as var. barbata Duval- Jouve. 

 I can see no Characea in the district. 



The more or less boreal character of the district is shown by the 



absence of Clematis Vitalba L., EpUobium tetragonum L., Bryonia 

 dtoica L., and Lysimachia Summularia L. ; and by the presence of 



several members of the subcristate section of Bma emina, Circaa 

 alpina L., which is more frequent than C. tutetiana L., Campam^ 



latifohu L. and Sallv pentandra L„ which last I have noticed in 

 three places. Appended is a list of such of the plants mentioned 

 above as are, so far as I can find, additions to the County Flora :— 



Strllaria media var. neplecta Weihe. 



Jtubus car pinif alius W. & N. 

 Rosa mollis var. ccemlea Woods. 

 & canina var. surculosa (Woods).
