and crown, thinner branches, later leafing, and earlier fall 
(CIESLAR: 1. c. 1914, pp. 171—174; vide SCHREIBER in Cen- 
tralb. ges. Forstw. 1921, p.p. 1—30 and pp. 76—99), and 
the larch which has been grown in Scotch forests for the 
last two hundred years is also regarded as a separate form 
with good qualities from the forestry point of view (G. 
SCHOTTE, 1917; A. OPPERMANN, 1923). The height of 53,7 m. 
with a corresponding diameter of 1,1 m. was found at 
Jägerndorf in the south of the Sudetic Range, which shows 
it to have been discovered within the area indicated by 
CIESLAR as being the district for the good Sudetic Larch. 
The European Larch is one which has been cultivated 
for a long period; it was introduced into Danish forests by 
v. LANGEN in 1763, or even perhaps in 1745, and is nowa 
common forest tree. One of the finest plantations is to be 
found in Tinghus Plantation in Grib Forest. It originates 
from 1777, and in 1923 the largest tree had attained a 
height of 34,5 m. with a girth of 85,5 cms. 1,3 m. above 
the level of the ground, this and other trees in the plan- 
tation being of particularly good shape (A. OPPERMANN, 1923). 
Herb, Mat. examined: 
Numerous cultivated specimens from Denmark, Sweden, 
Norway, Scotland, North America etc., in different herbaria.
