slight differences in the Mexican plants being due to the locality, 

 and easily paralleled by specimens from the warmer parts of the 

 Old World. In holding this view, Dr. Christ agrees with such 

 fern students as Hooker and D. C. Eaton, and probably expresses 

 the opinion of most students regarding the specimens in ques- 

 tion.

Some of our subscribers have recently complained that 

 The Fern Bulletin reaches them in a very crumpled state. It 

 is our intention to have the magazine appear in a flat and un- 

 wrinkled condition, and if those who do not receive it in this 

 shape will notify us, we will try to remedy the trouble. There 

 is no reason for the magazine being crumpled in the mails. 



NOTES. 



"The Pteridophytes of Minnesota,'" by Harold L. Lyon, has 

 recently appeared in "Minnesota Botanical Studies." Sixty- 

 nine species and varieties are listed, with notes on their distribu- 

 tion. It is to be regretted that the nomenclature of the list is 

 not the one in general use. This fact, however, seems to be ap- 

 preciated by the author, who gives the better known names as 

 synonyms. It is likely to be several centuries before fern s u- 

 denis will adopt Filix for Cystoptcris or Mattcuccia for Sfrutlii- 

 opteris. 



In the Japanese "Botanical Magazine." for April, there is a 

 list of Korean ferns collected by T. Uchiyama, which is of in- 

 terest from the number of species it contains that are also found 

 in Eastern America. Among them are the sensitive fern, ostrich 

 fern, marsh fern, male fern, beech fern, silvery spleenwort. lady 

 fern, bracken, royal fern and grape fern. Among the fern allies 

 are listed Marsilia quadrifolia, Salvinia Xatans. and three of 

 the Equisetums. The number of species that are common to 

 Eastern Asia and Eastern America is a never ending wonder to 

 botanists. No doubt in time there will be students to suggest 

 that the species are not identical because of the distances that 

 separate them.
