‘EXCURSION FLORAS”’ are useful in Europe, but no one has as yet 
included the whole of Europe. Franz Thonner* has just made the attempt, 
but is able to include only the genera of flowering plants. Characters are 
used so far as possible which do not demand the microscope for determina- 
tion, and the keys have been constructed with a view to rapid and easy use. 
Not only are the genera of Europe included, but also those of Iceland, the 
Azores, the Urals, and the Caucasus. The work follows the families and 
their sequence as given in Engler and Prantl’s Die nattirlichen Pflanzen- 
familien.—J. M. C. 
Dr. AUGUSTIN GATTINGER 5 has published a list of the vascular plants 
of Tennessee. This veteran botanist has long been active in the study of 
the very interesting flora of his state, and this volume forms a permanent 
record of his results. It includes 2218 species and follows the Engler and 
Prantl sequence. The title “Philosophy of botany” covers general papers 
under the titles “An epitome of the history and philosophy of botany,” “ The 
forest,” “ The introduction of a national forestry policy in the United States,” 
and “Modern thoughts on the origin, evolution, and significance of life.” 
Applications for copies should be sent to the author at Nashville, and should 
enclose ten cents for postage.—J. M. C.
