Bryum arcuatum, Andreæa obovata, À. Blyttü, being comparatively 
few. No doubt the sheltered conditions in the river ravines … 
accounted for a good deal, but it certainly seemed strange to see 
species of the temperate regions such as. Æncalypta ciliata, Bra-__ 
chythecium velutinum, Hypnum palustre, Bryum intermedium, 
B. pendulum, Leptobryum pyriforme, Swartzia montana, etc., 
not only flourishing but richly fruiting, in à latitude where they 
must be for five months in the grip of an arctic winter, with an 
average temperature for some months of from — 10° to — 20° C., - 
and an occasional drop to — 50°C. 
= We were rather struck with the poverty of representatives of 
the Splachnaceæ, both in species and individuals. Haplodon 
: Wormskjoldii was only seen twice and then in small quantily, 
Splachnum vasculosum and. S. sphæricum only once each, the 
larger Splachna not at all. It is possible that the hot dry summer 
of this year may have been adverse to the development of fruit ; 
and the apparent rarity of large animals may have contributed to 
was frequented by reindeer to some considerable extent. 
In the following list of species observed, where no locality is 
specified it is understood that the immediate neighbourhood of 
Abisko is intended. The latitude is given when, so far as [ am 
aware, the locality is the most northerly hitherto recorded; for 
this purpose 1 have relied on the data given in Hagen's Musci 
Norvegiæ Borealis (1899-1904). For the sake of convenient refe- 
rence I have used the classification and nomenclature of (hat 
work. À few species are included which we gathered at Kiruna, 
100 miles or so S. E. of Abisko. 
‘IL am indebted for help and for many suggestions to Mr W.-E. 
Nicholson, and for assistance in naming some of the critical spe- 
cies and in other ways to D" Hagen, Herr N. Bryhn, Dr G. Roth, 
and Mr A. Gepp. ; ss

above, with the alar cells strongly developed, and the upper cells 
 markedly papillose at back. It closely resembles a slender Dicra-

D' Hagen and other bryologisis ; the fruit however is quite 
the paucity of these plants, though the higher ground at least 4
