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



Sphagnum MuUeri. Dissodon splachnoides. 



teres. Webera albicans, var. glaciale. 



Girgensohnii, Bryum Duvalii. 



Campylopus compactus. latifolium. 



Splachnum vasculosum. Mnium cinclidioides. 



sphsericum. Hypnum trifarium. 



Tayloria serrata. sarmentosum. 



And on rocks in streams, 



Hypnum arcticum. 



At the same elevation, on the dry turfy edges of rocks, 

 are found : — 



Webera polymorpha. Oligotrichum hercynicum. 



Hypnum Mulilenbeckii. 



On dry rocks : — 



Grimmia patens. Dicranum virens. 



On damp rocks : — 



Hypnum callichroum. 



And on debris : — 



Conostomum boreale. Webera Schimperi ( Wils. not oiBry. Eur.) 



The upper portion of the mountain is composed of 

 micaceous schist, here forming precipices of considerable 

 extent, there broken up into enormous masses, tossed 

 about in an infinite variety of forms — and the surface of 

 the whole readily decomposing, and forming one of the 

 finest soils for alpine plants. No streams, and only one or 

 two minute runlets from bogs of very diminutive size, are 

 to be met with at this elevation. 



On ledges of the precipices, on grassy turf, and in deep 

 crevices of the rocks here, we meet with the following : — 



Weisia crispula. Tortula fragilis. 



Arctoa fulvella. Grimmia ovata. 



Dicranum virens. spiralis. 



falcatum. torta. 



Blyttii. Zygodon lapponicus. 



Starkii. Encalypta rhabdocarpa. 



longifolium. commutata. 



Stylostegium caespititium. Distichium inclinatum.
