This list adds 41 species to the 240 recorded in the article 

 above cited. Of the 26 Filefjeld species included in Hst, but not 

 definitely recorded for the limited district around Maristuen 

 worked by Miss Møller & the Rev. C. H. Binstead, two, viz. 

 Cynodontium gracilescens and Andreœa nivalis were verified by 

 us within that area, so that 257 species have now been definitely 

 recorded from the 48 square kilometres lying within the limits 

 defined by them. It may be added that in our case, as 'with 

 them, the weather was unpropitious for any careful examination 

 of the higher grounds. Dr. G. IN. Best who has published a 

 Revision of the N. American species of Pseudolekea (Bull. 

 Torrey Bot. Club 27, May 1900) has paid much attention to the 

 plants of the atrovirens group, and in the course of his investi- 

 gation has studied the types of several of our European species. 

 The result has been to elucidate several somewhat difficult points 

 and to throw some welcome light on a very obscure group. 

 What has come out most clearly is that under the term „Pseudo- 

 leskea atrovirens B. & S." have been grouped, and confused, a 

 number of forms, some at least of which are clearly specifically 

 distinct from one another. The first to be separated was the 

 plant described as Leskea? patens by Lindberg, (Soc. pro Fauna 

 et Flora Fenn. 1880), subsequently defined and described by 

 Limpricht as Pseudoleskea patens (Lindb.). This plant has 

 proved to be widely distributed over the European and North
