BOTANY 



Bawtry ; and Hypnum cordifolium occurs along the Rainworth Water, as 

 well as on the Keuper marl at Leverton, where it was discovered by the 

 Rev. A. Thornley. 



The Keuper marl and Lias clays possess few distinctive mosses, 

 Fissidens exi/is, Tortu/a paplllosa^ Earbula lurida^ Welsia squarrosa, Mnium 

 stellare and Erachytheclum illecebrum being among the more interesting 

 Keuper species, while Earbula recuruifo/ia has only been found on the Lias 

 at Gotham. 



In the following list of the mosses of Nottinghamshire, the arrange- 

 ment and nomenclature of Dixon's Handbook of British Mosses are adopted, 

 except that in the genus Sphagnum Horrell's European Sphagnaceae has 

 been followed. Species whose occurrence rests solely on the authority of 

 Howitt and earlier botanists are distinguished by the addition of the 

 name of the observer. For all others the present writer is responsible, 

 and it may be well to mention that specimens of all these species 

 (excepting the Sphagna) have been submitted to Mr. E. M. Holmes, 

 and in the case of all obscure forms to Mr. H. N. Dixon also ; no 

 doubtful species has been admitted to the list, and the identifications may 

 therefore be regarded as authoritative. The Sphagna were kindly named 

 by Mr. E. C. Horrell.
