the single systematic tribes, to a study of the different sorts 
of tissue and their different modes of formation. Hugo von 
Mohl and Anton de Bary, the founders of comparative anat- 
omy, may be regarded as also the founders of the anatomical 
method in systematic botany, the value of which was then 
fruitfully recognized by the systematists themselves, es- 
pecially by RADLKOFER (of Munich) in Germany, and before 
him, though not with such insistence on this point, by En- 
gler, Count SoLmMs-LAUBACH (Géttingen, Strassburg), and | 
Pfitzer. 
The most important German contribution of recent years 
to systematic botany is the work edited by Engler and 
PRANTL’ (Breslau) which has been in course of publication 
since 1889, ‘‘Die natiirlichen Pflanzenfamilien.” Many, for 
the most part German, systematic botanists united to work 
up the material which has been accumulated in course of time 
and by their own exertions, and to give a uniform pres- 
entation of the numerous families of plants in accordance 
with the new points of view, combining comparative morphol- 
ogy, development, anatomy, and the results of biological re- 
The systematic study of the cryptogams shows no less ad- 
vancement during recent decades than that of the phanero- 
gams. The alge were especially worked up by TRAUGOTT 
KUETZING (teacher in Nordhausen) in his ‘‘Tabule Phyco- 
logic,” published from 1845 to 1870 in twenty volumes, and 
in numerous other works; the fungi by P. MAGNUS (Berlin), 
G. WINTER (a scientific man in Leipzig who held no public 
office, and who died in 1887), and J. SCHROETER® (high mil- 
itary surgeon in Breslau). We must thank the latter for a 
fungus flora of Silesia whichis now nearing completion. The 
mosses received fundamental treatment at the hands of W. PH. 
SCHIMPER (Strassburg, died in 1880), and finally the vascu- 
lar cryptogams by MILDE (Breslau, died in 1871) and 
LUERSSEN (of Kénigsberg). ; 
The study of plant-geography in the German Universities 
attained to greater importance first under GRISEBACH (Gdot- 
tingen, died in 1879). His most famous work undoubtedly 
is ‘‘Die Vegetation der Erde,” which was published in two 
volumes in the year 1872. Grisebach considered climate to
