merated here, the author would be happy to receive Communications adressed to Mr. Sonnewald, the publisher. ■ An almost uninterruptcd succcssion of fir- and pine forests covcrs tbc teddish sandstone lieigbts of tbese moun- tains. The red fir is predominant in tbe higher regious, while fartber down tbe silver fir becomcs morc conspicuous. The shady ground of tbese woods presents tbc aspect of a soft mossy quilt, interwoven witli bcautiful ferns, of whicli tbe inost remarkable are: Aspidium spinulosum, Lonchitis, Oreopleris, Filix mns. and Filix foemina, fragile, aculeatum , and anlhricifolium ; Polypodium pltegopleris, thelypleris, oreopleris , dryopteris, and dilalalum; Blrchnum boreale; and Osmunda regalis. All tbe prominent rocks left free from liioss, are clotbed witli lsidium corallimim, and Byssus (Chroolepus Jolilhus) , wliile tbosc most exposed to tbe north- winds aie overgrown witli an array of grey or black co- loured licbens, connnonly cousidcred as tbe sole property of tbe Flora of tbe scandiuavian provinccs. Of tbese tbe rarest are: Farmelia falilunensis , slygia , and excausla; Gy - rophora glabra , proboscidea , cylindrica, erosa, deusta, puslu- lata; Cornicularia pubescens ; Stercocaulon pasckale. The scarc-est species of tliis Order however are nourished by tbe bark of tbe forest trees; — tbe milk coloured Tbelotrema ( The- lotrema Irjiadinum): Spkaerophoron coralloides, and fragile; also common liverwort ( Sticla pulmonacea), Lecidea san- guinarea; and numerous Parmeliae. ln tbe highest regions, finally, broad, greyisli-green bands are seen between the dark leaves, they mostly are of tbe species: Alccloria jubnta and sarmentosa; Borrera ciliaris, furfurucea • and Usnea fori da , and barbata ; — sickly trees here are overspun witli tbe long tbreads of Usnea longissima , and decayed stems serve as abode to peculiar formations, like Buxbaumia aphglla, and Lecidea comadophila.
