is without proper representation. The alpine flora has received full treat- 
ment, and special attention has been paid to the endemic genera. The editor 
says that he has also illustrated a number of plants of special interest “either 
on account of their economic value, or from biological or morphological reasons, 
or from their peculiar geographical distribution.’”” He has not thought it 
necessary, however, except in a few special cases, to figure plants occurring 
in other countries as well as New Zealand. 
It is interesting to note the result of the selection, as expressing in a 
general way the editor’s opinion of what constitutes the main features of the 
New Zealand flora. Without going into detail, it may be stated that i 
families represented in this selection by more than ten species are as follows 
Compositae (35), Gramineae (17), Filices (17), Orchidaceae (15), Unibelliferns 
(12), Scrophulariaceae (12).—J. M. C. 
MINOR NOTICES 
Pharmacognosy.—K RAEMER? has published a textbook of pharmacognosy 
which is encyclopedic in its wealth of information. He recognizes the synthetic 
character of the subject, especially in its combination of botanical and chemical 
aspects. Moreover, both of these aspects are shown to involve the ecological 
conditions under which plants grow, s o that scientific pharmacognosy is a 
involved, the great plant groups are presented, the large majority naturally 
being families of angiosperms, 94 in number, from which drugs are obtained. 
As stated by the author, the book is intended for students of pharmacy, 
pharmacists, food and drug analysts, and pharmacologists. We might add 
to this list students of economic fans for pharmocognosy is one of the 
great fields of applied science.—J. M 
Citrus fruits—Corrs has published as a volume of Bartey’s ‘Rural 
Science Series’? an account of the citrus fruit industry, with special reference 
to the requirements and practices for California. It seems that the citrus 
industry has not only reached a high state of development in California and 
Florida, but is still progressing rapidly. The present volume discusses the 
underlying principles in such a way as to emphasize the importance of certain 
fundamentals which must be kept in mind. The industry as it exists at present 
is described, and all current information that seems valuable is organized and 
made available. Of special interest to the botanist are the chapters dealing 
with the geography and climate of California, the gross structure and habits 
- of growth of citrus plants, and the citrus diseases and their control.—J. M. C
