Species Hepathicarum. Recensuit, partim descripsit, iconibusque illus- 
travit J. B. G. Lindenberg. Fasc. 1. Jungermanniez Plagio- 
chila. 
The study of the interesting family of the Liverworts, which fora 
long time had been but slightly cultivated, has of late acquired many 
friends and active attention. ‘The author of the present work, al- 
ready well known to us from his love to this group, at present fa- 
vours us with the commencement of a work which will supply what 
has long been a desideratum. ‘There were descriptions enow of 
Liverworts, but accurate and good drawings were highly desirable, 
and a complete comparison of all known species was still entirely 
wanting. «As a systematic order of succession could not be followed 
throughout in this work, the author has preferred to take the species 
generically, and thus form a series of monographs, which, at the 
conclusion, will be connected by the requisite synopsis and Index, 
in which the other relations also of the family will be treated of in 
general. The present part contains the genus Plagiochila, Nees et 
Mont., with eighteen species. The drawings resemble those of the 
mosses by Schwagrichen, but are lithographed and partly coloured. 
The whole work is exceedingly well got up, and will, undoubtedly, 
meet with a good reception from the botanical public. The text 
is arranged in the following order: diagnosis, synonymy, country, 
with discoverer, descriptions, then observations, and lastly, explana- 
tion of the figures. 
Die Naturlichen Pflanzensysteme, geschichtlich entwickelt, von Dr. 
H. L. Zunck.—A Prize Memoir crowned by the Philosophical Fa- 
culty of Leipzig. 
An historical exposition of the development of the natural system, 
carried out with great ability. The author, after having established 
the difference between artificial and natural system, gives a com- 
densed review of the progress of botanical knowledge from the time 
of the Greeks and Romans to the establishment of natural classes 
and families; then estimates the attempts of various authors, from 
Adanson to Endlicher ; and lastly, gives a tabular synopsis of the 
systems after their classes. We could have wished, for the sake of 
completeness, that the author had mentioned the attempts of Fries, 
Wilbrand, Aspegren and others; and that at the conclusion he had 
represented in a table, by adposition of the allied classifications, the 
relations they bear to one another.
