The Japanese Larch is only found in the wild state 
in the interior of Hondo at about the same latitude as 
Tokio, while it is cultivated in the north and south, and 
also upon the large islands of Hokkaido, Schikoku, and 
Kiuschiu. Its area of distribution runs roughly east and 
west across Hondo from the province of Kaga in the west, 
through Shinano to the district around Nikko in the province 
of Shimotsuke, where it reaches its most easterly and most 
northerly point of occurrence. The area forms a belt 80— 
100 km. wide, and 250—300 km. long (see Map V). It is 
common within these limits, and grows at an altitude of 
between 500 and 2300 m. above sea-level, keeping to the 
volcanic soil. On Fuji-Yama it occurs right up to an 
altitude of 2900 m., but, at the extreme limit, only as a 
stunted bush hardly Im. high (Murray: 1863, p. 97). 1.G. 
VEITCH was the first to draw attention to this form, which 
Murray in 1863 described as a separate species, L. japonica 
(non Carriére). After its subsequent introduction to the 
Arnold Arboretum in 1892, it has been demonstrated that 
it does not retain its dwarf growth, and does not deviate 
from the species in any important characteristic.
