MR. G. E. HUNT ON MOSSES NEW TO BRITAIN. 233 



fruiting less freely than S. cuspidatum. S. laricinum, 

 Spruce^ is a variety of this species^ and not of S. contortum 

 as formerly supposed. A form intermediate between the 

 two occurs abundantly on Carrington Moss. 



Sphagnum curvifolium, Wils. MS. Allied to 8. sub- 

 secundum, but differing in the cortical layer of the stem 

 having two or three rows of cellules (whilst there is only 

 one row in S. subsecundum) , in the absence of marginal 

 pores to the leaves, and the entire acute leaves. A more 

 brittle plant than its ally, discovered by Mr. Wilson in 

 Cheshire, whose description I copy. I believe it to be very 

 abundant near Portree, in Skye. 



Ephemerum tenerum, Br. and Sch. Weald of Sussex, 

 Mr. Mitten. 



Seligeria tristicha, Brid. On calcareous rocks, Blair 

 Athol. Berkeley's Hand-book of Mosses, 1863. 



Seligeria calcicola, Mitt. [S. subcernua, Lindb. ; Gymno- 

 stomum paucifolium, fide Carruthers in ^Journal of Botany^). 

 Allied to S.pusilla, but with the leaves of a brighter green, 

 wider at the base, more acute above, nerve narrow. On 

 chalk, Sussex Downs, Mr. Mitten. 



Dicranella curvata, Hedw. Llanberis, North Wales, 

 Mr. Wilson. 



Dicranum longifolium, Hedw. Ben Lawers, July 1866, 

 Dr. Stirton. 



Dicranum viride, Lindb. Staffordshire, Mr. Bloxam; 

 identified by Mr. Wilson. 



Dicranum trichodes, Wils. Probably a Blindia, but, I 

 think, distinct from our British species Blindia acuta, to 

 which, however, it is allied. Rocks near Bolton, J. White- 

 head. 



Dicranodontiwn aristatum, Sch. First discovered by 

 Mr. A. M^Kinlay on rocks, Lennox woods, near Campsie ; 

 occurs on nearly all the Scotch mountains, always, accord- 

 ing to M^Kinlay, in company with Dicranum circinatum,
