Part VI. of the second series of the Minnesota Botanical Studies 

 has recently appeared. It contains three articles, as follows : Lichens 

 of Northwestern Minnesota, by Bruce Fink ; Corallinae verae of Port 

 Renfrew, by K. Yendo, and Observations on Pfe^-ygopJiora, by Conway 

 MacMillan; also an index to the volume. 



Editorial. 



We have observed some comments on the existence of two societies 

 devoted to plant protection, and there have been inquiries as to the 

 reasons why a consolidation has not taken place. It may be well to dis- 

 cuss this matter at some length, in order to prevent possible misunder- 

 standing and appearance of rivalry. The Wild Flower Preservation 

 Society of America, soon after its organization as a national body, with 

 representatives of all sections on its board of managers, extended to the 

 Society for the Protection of Native Plants, in Boston, an invitation to 

 become the first of its local chapters ; but the offer was courteously de- 

 clined by the older society for the reason that its policy was already 

 established, with definite lines of work in operation, and that although 

 strictly local in management its membership represented a number of 

 States. While it is to be regretted, from many standpoints, that the 

 uaiion could not have taken place, yet there is room for such wide activ- 

 ity in the common cause that no possible harm can result, and the two 

 societies will undoubtedly work together as harmoniously as if they ex- 

 isted under one head. 



In the current issue of Rhodora, Dr. B. L. Robinson has given a 

 most excellent presentation of the work of the New England Society, and 

 of the conditions demanding missionary efforts. In this connection we 

 would recur to the much discussed advertisement of the botanical fea- 

 tures offered by a trip to northern Maine via a certain railroad, an 

 advertisement which has appeared for some months in Rhodora, and 

 which we notice has been recentlj^ rewritten and considerably amplified. 

 It will be remembered that we made some editorial utterances on this 

 subject in our issue for October, 1901, though without mentioning by 

 name the journal in question. This editorial elicited strong protests 

 from several of our New England friends, who regarded our remarks as 

 an affront to the local fraternity. We had not supposed that the lan- 

 guage of the editorial could be so construed, but in the light of the earnest
