1900] CURRENT LITERATURE 67 
Without changing the plan of the book its statements have been changed to 
conform to recent discoveries. But a more thorough change, especially to 
strengthen the physiological section (of only 50 pp.), seems desirable. The 
main emphasis is laid on the third part, the taxonomic synopsis of the plant 
kingdom, nearly half the book being devoted to descriptions of families and 
orders of phanerogams. There must be a demand for this sort of thing in 
Germany, especially in the schools of pharmacy, else there would not be so 
many text books in which it is prominent. But it is hard to see of what 
devoted to a thorough discussion of the fundamentals of morphology and 
classification. — C. R. B. 
THE FIRST FASCICLE of the list of the genera of seed plants, according 
to the system of Engler, has appeared.’ The large page is divided into two 
columns, and all of the divisions down to the genera are given. The genera 
are numbered in double sequence, the first number indicating the place in 
the whole series of genera, the second number indicating the place in the 
family. In these first signatures 1268 generaare listed, beginning with Cycas 
and closing with Marica (Iridaceze). Under each genus there are given the 
important Citations, the synonymy, the approximate range and number of 
Species. In the case of larger genera the section names and their synonymy 
are given. This work will not only be indispensable in herbaria, but will be 
amine of handy information to the general student of morphology and tax- 
onomy.—J. M. C, 
A NEW EDITION of the Bonn text book,® the fourth, has been issued by 
Fischer, with the purpose of keeping this incomparable work abreast of the 
Science of botany. The authors have incorporated from the newer literature 
everything which appears to them to be of scientific or didactic value. Cer- 
tain sections of the part on external morphology have been extended, some 
new illustrations have been added and some old ones replaced by better. 
The general Plan of the book is not altered. It has become so well known 
that there is no need to speak of its merits or defects. We hope that the 
translator of the English edition will take advantage of the new German 
edition to bring the English one also up to date and correct some slips of 
translation C. R, B, :
