Vermont may fairly be called the home of Calypso, but if some bot- 

 anist between Sitka and Superior shall write me that he finds Calypso

NOTES AND NEWS. 



J. W. Toumey has been elected botanist to the state college and 

 experiment station at Tucson, Arizona. 



The last part of a key to the genera and species of British mosses

The summer school of botany at Harvard University closed August

Proe. Dr. Karl von Xageli, of the University of Munich, author of 

 many valuable botanical works, and a philosophical botanist of deep 

 insight, is dead at 74 years of age. 



The library of the late Dr. Schenk and that of Dr. Karl Sanio, 

 who died last February, have been purchased by Weigel (Leipzig) and 

 the works will shortly be offered for sale. 



Dr. Edward Palmer, the well known collector, started about the

Von Tubeuf has lately published a book 1 which contains good and 



practical hints as to the identification of German forest-trees at a stage

 structure of the P&tamogetonacem.* The principal purpose of his in- 

 vestigations were not only to give a general sketch of the interna 

 structure of the leaf, but also to show the importance of anatomical 

 characters in identifying species, when represented merely by frag-

 medium After giving some introductory remarks concerning the 

 classification of this group and the general influence of medium upon
