287. 1916.) 



The treatment of the forms of the genus Rosa has recently in 

 Scandinavia been altered completely through the investigations 

 of S. Almquist, R. Matsson and others. The main principles of 

 their Classification of the numerous forms are the foUowing: they 

 admit a number of groups: Vülosae, Tomentosae, Rubiginosae, etc., 

 answering to the old collective species. On the other hand the 

 same special characters, especially as regard the leaves, reappear 

 in each of the groups; in this way we get so-called "special types", 

 and by using them it is possible to arrange the forms in a manner 

 quite different from the Classification according to the groups. If we 

 combine these two methods, the arrangement becomes like that of 

 a chess-board, and Almquist has also compared it with Mende- 

 lejeff's System. 



In the present paper the author has given a general introduction 

 into the modern rodology from which the above remarks have been 

 taken. Then follows his enumeration of the "species" found in 

 Den mark, arranged according to the "special types", and within 

 the special types according to the groups. This arrangement makes 

 a Strange Impression at first sight as we are accustomed to use the 

 groups as the principle of Classification. 



From examination of the Copenhagen herbarium and some 

 other herbaria the author records about 75 "species" for Denmark; 

 of these 11 are described as new (besides several new "sub-species"). 

 An artificial key arranged according to the well-known groups is 

 added to the paper and increases its usefulhess.

E. australiana n. sp. has been known as the "narrow-leaved 

 peppermint". It was formerly included under E. amygdalina, but 

 proves to be distinct and allied to E. piperita. E. M. Cotton.
