the specimens are old individuals, and young trees are not 
common. The photographs kindly sent by SZAFER certainly 
bear witness to trees of considerable size, but unattractive in 
shape (Figs. 25 and 26). The first plantations visited by Racı- 
BORSKI are said to have been very beautiful, and CIESLAR was

thus induced to suggest a trial with the Polish Larch in 
forest culture, as he thought it would prove to have the 
same valuable properties as the larch in the Sudetics 
(CIESLAR IL. c. 1914, pp. 182 and 183). 
The systematic position of the Polish Larch having 
been demonstrated, as an intermediate form between the 
European Larch and the West-Siberian species, a possibility 
is obtained of being able to explain the systematic position 
of the larch in its spontaneous occurrences in Rumania, 
where it has been classified alternately as L. decidua and 
L. sibirica, but the question is still incapable of a full 
explanation.
