student can say with considerable certainty what ferns will be 

 found in a given locality when still some distance from it.

We thus find ourselves at the beginning of another period in 

 the study of ferns. Our principal forms are well known ; to what 

 shall we now turn our attention? Shall it be the cultivation of 

 ferns and the hybridizing of species, or shall we follow European 

 precedents and give more attention to variant and abnormal 

 forms? As we have said, the amount of technical matter is 

 decreasing, and we have some doubts in selecting matter for this 

 magazine, whether it is best to use articles bearing on fern 

 culture or to use material of a more general nature to supply 

 the deficiency. We would be glad if our subscribers would in- 

 dicate their desires in this matter.

It has seemed to us that American fern students are familiar 

 enough with our ferns to welcome information about exotic ferns, 

 especially those from the American tropics. In subsequent num- 

 bers we shall endeavor to pay more attention to this phase of 

 the subject. It is not intended, however, to overlook the ferns 

 nearer home and articles and shorter notes upon our ferns will 

 be gladly received.

Mr. Aug. H. Hahne, of Bonn, Germany, has kindly under- 

 taken to supply us with an index to the current literature of 

 Europe relating to ferns. The first installment appears in this 

 issue. Americans as well as Europeans will doubtless be inter- 

 ested in it. Any corrections or additions to the index may be 

 sent to Mr. Hahne or to this office. 



In publishing upon a collection of ferns from Southern 

 Brazil in Hedwigia, Dr. E. Rosenstock describes a new species of 

 Nephr odium as N. pseudothelypteris. It grows in situations 

 similar to our well known marsh fern. It is interesting to note 

 that Osmunda cinnamomea is also found in that far away region.
