“REVUE BRYOLOGIQUE 
on examination at home it was found that part at least ofthe 
wegian Arctic Expedition (Kristiana, 1907), and I have tabulated 
their occurrence or non-occurrence below. 
gathering was dioicous. I sent a specimen to Herr Bryhn, contain- 
ing some rather poorly developed © flowers among the fruiting 
stems, for his opinion; and he wrote that while the leaf-structure 
- would apply equally to €. arcticum or C. slyqium, the © flowers 
were not the large terminal discoid ones of €. arcticum, and he 
was disposed to look upon it as a lusus naturæ of €. stygqium. 
Further examination of my plants however revealed several of the 
conspicuous terminal discoid © flowers entirely agreeing with 
those ot C. arcticum, in my herbarium, and M Nicholson finds 
the same on his specimens, 50 that I have no doubt it is correctly 
referred to C. arcticum. | 
. Another Cinclidium from Vassitjakko without fruit had young 
flowers containing archegonia alone. 
= Paludella squarrosa Brid. Abundant, but so far as we saw 
always sterile. se 
Meesia trichodes Spr. cfr. — M. triquetra Angstr. st. e 
Catoscopium nigritum Brid. cfr. Sometimes very dwarfed. In 
some of the drier peat bogs producing fruit, as already remarked, 
in immense quantities. 
_ Aulacomnium palustre Schwægr. st.— À. turgidum Schwægr., st. 
Bartramia üthyphylla Brid, cfr.

Conostomum boreale Sw. Vassitjakko, st. : 
Philonotis tomentella Mol. Abisko, cfr. Common on the rocks inf 
the cânon, generally a form with most abundant caducous ramuli 
(£. gemmiclada). 
immia comata Lindb. et Arn. (7°. elegans Hagen). Abundant on . 
wet rock ledges, Abiskojokk, Koppajokk, st. There can I think be 
no doubt of the identity of 7’. elegans with Lindberg and Arnells 
species. It is a distinet species, having something of the habitofa 
very slender 7. norvegica, With the leaves, especially the comal 
ones, highly brittle. — 7. norvegica Zett. st. — T. austriaca 1 
Hedw. st. À form from Vassitjakko had curiously secund leaves. 
Olicotrichum hercynicum Lam. st. À very dwarf, bright green, 
small-leaved plant covered large patches of ground near Abisko. : 
 Pogonatum capillare Brid. Abisko, mostly sterile (only Lwo cap- 
sules found) ; Vässitjakko, up Lo 1300 m., st. À plant from Bjürkli- 
den had the terminal cell of the lamellæ less flattened and more 
like that of P. urnigerun, but seems nearer P. capillare, P. urni-
