MONOGRAPHS FOR AN AMATEUR GARDENER'S LIBRARY. 371 
botanical monographs published in the present century ; and though, 
with two exceptions, the sixty-one parts so far issued are in German, 
with Latin diagnoses and critical notes, certain parts dealing with plants 
important for gardens are of great service to amateurs interested in 
those families. 
The great value of these lies in the excellent keys, not only to the 
genera, but to the sections of large genera and the species of each 
section, and the mass of references to literature and geographical 
distribution. 
There are a few outline figures in the text which are good in repre- 
senting dissections, so good and so few as to make one wish for more. 
In times of peace it was easy to purchase the various parts sepa- 
rately, if desired ; and, in the hope that it may be possible again before 
very long, I give a list of the more interesting families included in 
those published already :
