NOTES ON YORKSHIRE MOSSES AND HEPATICS. 

 By G. Stabler. 



Whilst looking over some recent numbers of the Naturalist, it 

 occurred to me that it might be of interest to its readers if I noted 

 down a few of the rarer mosses and hepatics which have been 

 gathered in the Dent valley, or more correctly speaking, in that part 

 of Yorkshire to the left of the Dee, and which joins Westmoreland, 



The lists of Yorkshire mosses and hepatics in my possession are 

 the following : — the Musci and Hepaticce of Teesdale, found by Dr. 

 Spruce ; the list of mosses in Baker's " North Yorkshire "; and 

 Hobkirk's "Mosses of the West Riding of the County of York" 

 (1873). I will therefore abstain from mentioning any found in the 

 foregoing lists. 



I have the permission of my friend Mr. Barnes to say that on the 

 27th of December, 1872, he gathered Grimmia conferta on the hills 

 growing on a crumbling kind of dark-coloured rock or clay. In the 

 same year I also found Spliagnum teres and Habrodon Notarisii — the 

 latter on an ash near the river, and since that time on sycamore near 

 the same place. 



Dr. Spruce's list is the only one of the three above mentioned 

 which includes Hepatica, and being a record of plants observed by my 

 eminent friend during one journey in one valley in the county, it is 

 necessarily less comprehensive than the lists of the other two 

 botanists, and this is why I have to enumerate more hepatics than 

 mosses. 



In the year 1872 I paid two visits to Dent, and along with many 

 other species, were collected the following : — PlagiocJiila spinulosa, 

 N. ab E ; Jungermannia Genthiana, N. ab E. ; J. pumila, With, ; Sacco- 

 gyna viticulosa, Dum. ; Mastigohyum trilobatmn, N. ab B. ; Lejeunea 

 minutiss'ma, Dum. (on trees) ; Frulla?iia fragilifolia, Tay ; Metzgeria 

 conjiigata, Lindb. ; Rehoidla hemispJirica, Radd. ; Pellia calyclna, N. 

 ab E.' 



On the 1st of September, 1877 (I will not disguise my feelings on 

 the occasion) I was delighted to find Lejeunea hamatifolia growing in 

 the same district ; and this leads me to think that I could not find a 

 more fitting opportunity to place on record something I have done. 

 It is this : Dr. Moore, of the Royal Botanic Garden, Glasnevin, with 

 his usual liberality sent me fine living specimens of Dumortlera irrigua 



N. S., Vol. iv., Mae., 1879.
