racteristie of S. subimmersa. Herr Bryhn, to whom we submitted 
_it later, recognized the differences from S. subimmersa, bul taking 
into account the general resemblance he was inclined to consider 
_iteither a variety or an unusual state of that species. Under those 
circumstances I have thought it best not to create a new species, 
but to place it provisionally under S. subimmersa.

Abisko, cfr. We gathered this species very well characterized at 
Narvik on the Norwegian coast (Tromsô Amt); at Abisko it was 
somewhat less distinct, and the specimens of 7°. cylindricus, which 
was abundant and fruited richly about Abisko, usually showed 
-_ sone approach to it in the shorter, stouter seta, shorter capsule, 
- larger spores, etc. Et 
Ditrichum tortile Lindb. Kiruna, abundant, cfr. Perhaps best .

caule Hampe, st. Common, and very variable. A form with short- 1e 
leaved, caducous flagella, occurred at Abisko and Palnoviken. The _ 
leaf cells are at times distinctly larger than in southern specimens.

Distichium capillaceum B. etS. cfr. Sometimes with capsules 
very short, almost the form of D. inclinalum, but ereet or nearly s0. 
— D. inclinatum B. et S. cfr. In addition to typical inclinatum 
we gathered a plant which in form of capsule and some other 
characters manifested a resemblance to D. Hagenü Ryan; the 
spores and peristome however show it to belong Lo D. inclinatum.
