In the Bryologist for May, 1920, the writer reviewed No. 5 of this series, 
dealing with the first part of Polytrichaceae, and expressed, the hope of seeing 
the rest of the series. They are all on hand now, up to date, owing to the kind- 
ness of Mr. Moller, and form a valuable addition to the literature of the per- 
ennially interesting Scandinavian moss-flora. This is always useful to the student 
of the mosses of northern New England, particularly of those of Vermont. 
I. Deals with Splachnaceae, genera Splachniim, Haplodon, Tetraplodon, and 
Tayloria. They are evidently much more frequent than with us, except perhaps 
in the subalpine regions of Maine. In this installment, as in all the rest, a very 
comprehensive list of Swedish stations is given, and most excellent critical notes.
