tribution of Lichens. "Whatever may be the case with regard to the 
two latter points, we cannot think that much has been done in the 
matter of the organs of reproduction. No doubt Tulasne’s demon¬ 
stration of the prevalence of spermogonia was of great importance, 
but it is quite premature to speak of these organs, (as Dr. Stizen- 
berger does,) as “mannliche Befruchtungsorgane,” and indeed we 
believe that this view of their function is doubted, even if it has not 
been abandoned by Tulasne himself. 
Dr. Stizenberger gives a short sketch of the different systems, 
placing Nyfander’s and Korber’s arrangements (which he calls 
thallistic (thallistischen) systems,) in opposition to those of Nageli, 
Berkeley, Theodore Fries, and Massalongo, which he calls carpolo- 
gical. It seems an error to call Berkeley’s system “ carpological,” 
at least in the sense in which that word would be applied to the 
arrangement of Massalongo. A system in which Lichens are divided 
into “angiocarpi” and “ gymnocarpi,” may have very little in com¬ 
mon with a system in which genera are founded upon distinctions 
existing in the sporidia, and to which alone the definition “ carpolo- 
gical” can be properly applied. 
LI.II. —Jahrbucher fur wissenschaftliche Botanek. Heraus- 
gegeben yon Dr. N. Pringsheim. Dritter Band. Zweites 
Heft. Berlin, 1862. 
In the able periodical mentioned at the head of this article, as well 
as in the Botanische Zeitung of Berlin, and the Begensburg Flora, a 
large proportion of space has always been, and still is, devoted to 
Cryptogamic Botany. The family of the Algse has hitherto received 
the most attention in Dr. Pringsheim’s book, a circumstance by no 
means to be regretted, as the Lichens are carefully looked after in 
the “ Flora,” and the Botanische Zeitung divides its favours pretty 
equally amongst all the Cryptogamia. In the part of the above 
work which is now before us ( Vol. 3, Part 2), we find three papers, 
to which we wish to direct the attention of the readers of this 
Beview. The first is by Dr. Hofmeister, the second by Dr. Prings- 
beim, and the third by Professor Cienkowski. Dr. Hofmeister’s 
paper is entitled “ Zusatzeund Berichtigungen zu den 1851 veroffent- 
“ lichten TJntersuchungen der Entwickelung hoherer Kryptogamen.” 
It is not necessary, as far as English readers are concerned, to do 
more than to mention the title of this paper, as the “ additions and 
corrections” referred to have been embodied in the Bay Society’s 
English Translation of the new MS. edition of Dr. Hofmeister’s 
work. In the present paper the author has afforded to the botanists 
of Grermany an opportunity of studying these additions and correc¬ 
tions in their own language. 
The second paper above alluded to is one by Dr. Pringsheim, 
the title of which is as follows: “Ueber die Vorkeime und die
