Outside the area of distribu- 
tion hitherto treated of, the 
European Larch appears also 
in Poland as a special race.

localities where fossil remains are found, north and east 
of the existing remnants of the primitive larch forests in 
Poland, thereby proving that the larch enjoyed a wider 
distribution in prehistoric as well as early historic times 
than it does at the present day. All these forests of wild 
larch, however, were classified by KÔPPEN as well as by 
all other botanists of an earlier date as L. decidua, until 
Racısorskı in 1890 showed that the larch from the old 
Polish stock differed morphologically from the typical 
European Larch, and bore a close resemblance to L sibirica, 
for which reason he classified it as an independent species, 
L. polonica. 
SZAFER in 1913 went closely into the question regarding 
the justification of its being regarded as an independent 
species, and gave the first detailed description of its charac- 
teristics, at the same time examining it on the spot. The 
result of his observations convinced him, that the classi- 
fication was justified, and that its systematic characteristics
