320 MR. G. E. HUNT ON THE RARER MOSSES 



somewhat firm growth; leaves rotundo-ovate^ rather con- 

 cave, suddenly apiculate, texture very close, areolae long 

 and very narrow ; nerve double, short, slender, but well 

 defined. Growing at a low elevation. Localities in 

 Britain — North Wales, Yorkshii'e, Perthshire, Clova, 

 Braemar ; widely distributed on the Continent. 



H.molle, Dicks. [H. alpestre{?), Bry. Eur., not of Swartz) . 

 Plant very weak and flaccid, the tufts falling to pieces on 

 being removed from the water ; leaves varying from ovate 

 to rotundo-ovate, flat, or sometimes very slightly reflexed 

 towards the apex, gradually tapering upwards, or very 

 rarely suddenly apiculate ; texture somewhat loose, areolae 

 larger and wider than in H. dilatatum ; nerve rather long 

 and thick, ill defined, single or double. Growing at a 

 great elevation. Localities in Britain — Ben-mac-dhui, 

 Ben Nevis; on the Continent — Norway and Switzerland. 

 This plant is very liable to be passed over as H. ochraceum, 

 as it much resembles, in general aspect, some forms of 

 that species. 



H. alpestre, Sow., is to be expected in Scotland ; it is to 

 be distinguished by its elliptical, very concave leaves, with 

 the margin conspicuously reflexed towards the apex, which 

 is usually itself recurved; nerve double, rather thick, 

 distinct. Found in Norway. 



Dicranum arcticum, Sch. (Z). Starkii y8. molle, Wils.). 

 Although described under the latter name in Wilson's 

 ^ Bryologia Britannica,' it has for some time past been 

 nearly lost sight of in Britain, and is so little known 

 in Europe that in 1866 it was figured and described in 

 Part 3, Suppl. to Bry. Eur., by Dr. Schimper as a new 

 species, allied to Starkii, the only European station there 

 mentioned as known being the Dovrefjeld, in Norway; 

 also found in Greenland and Labrador. Its general ap- 

 pearance better distinguishes it from D. Starkii than its 

 microscopic characters. It is quite erect, growing in large
