The Mosses of Java — “Die Musci der Flora von Buitenzorg ” (Zugleich 
Laubmoosflora von Java) Max Fleischer. 2 vols. 8. vo. pp. .643 XXXI, 
with 120 illustrations. E. J. Brill, Leiden, 1904. 
These two interesting volumes contain not only many additions to the 
Flora of Java since the publication of The Bryologia Javanica in 1861, but 
they also emphasize the importance of the peristome in classification as may 
be seen by the Systematic Synopsis given in the preface, where the Bux- 
baumioideae, Tetrapoidoideae and Encalyptaceae constitutes separate 
orders and classes to which Prof. Fleischer has given new names. Thus far 
only the Sphagnales and Bryales have been issued, but these include many 
new species and original illustrations. The remaining volumes will be 
awaited with much interest. Elizabeth G. Britton,

MUSCI IN ENGLER AND PRANTL’S NATURLICHEN PFLANZEN= 
FAMIL1EN. 
John M. Holzinger. 
This great work on the mosses of the world was begun in December, 
1894, by Dr. Carl Muller Berolinensis, who, as he himself explains, must be 
distinguished from Carl Muller Hallensis. The Hepaticae are treated in 
pp. 3-141 by V. Schiffner. Musci begin on p. 142, and in the last number 
recently issued continue to p. ^24, approaching the close of Acrocarpi, but 
Dr. Muller’s contribution ceases on p. 202, comprising a very valuable 
enumeration of the most important literature, which covers twelve pages of 
closely printed lists of works, both early and recent, dealing both with the 
developmental history, the systematic arrangement, and the geographical 
distribution, this last arranged according to continents and countries. 
This author’s treatment from pp. 154-202 does not pass beyond the stage 
of the introductory discussion of the life history and of forms of propagation 
and the anatomical investigations of organs. On p. 203 Dr. Engler 
explains that the author by reason of pressure of official duties could not con- 
tinue the elaboration of Musci for the Pflanzenfamilien, and that in con- 
sequence Dr. W. Ruhland will complete the elaboration of the propagation 
and life history of the Musci. Dr. Carl Warnstorf will contribute the sys- 
tematic treatment of Sphagnaceae, and Dr. V. F. Brotherus that of the 
remaining families of Musci. Therefore from p. 203-243 Dr. Ruhland goes 
into great detail in discussing and illustrating by figures the propagation by 
sexual and vegetative methods of Musci and their life history. He also 
contributes an introductory chapter on general relations both to Sphag- 
nales, to Andreaeceae and Bryales. Dr. Warnstorf then treats Sphag- 
naceae systematically, pp. 248-262. Dr. Brotherus covers Andreaeceae, 
on pp. 265-268, and Bryales from p. 277 on to p. 624, this last number of 
Pflanzenfamilien having recently appeared (April, 1904).
