The English physician and traveller, WILLIAM GRIFFITH, 
discovered this larch in 1838 in Bhutan, near the village 
of Woolakoo, a little S. W. of Punakha in the Himalayas; 
this has subsequently been shown to be one of the most 
easterly localities within the inconsiderable zone of distri- 
bution, which extends from this spotin a westerly direction, 
and is assumed to reach about as far as the source of the 
Kosi river. The whole extent of the area within the bounds 
of which it is known is hardly 500 km. at its greatest 
length (from east to west) and 100—150 km. broad from 
north to south, and the only specimens seen by us are 
derived from the easterly section, that is to say, from the 
most westerly portion of Bhutan, extending a short distance 
into Nepal, together with the interlying Sikkim, and the 
southern point of Tibet, which extends between Bhutan 
and Sikkim. More recent discoveries of this larch have 
been made in localities situated between the most westerly 
regions of Bhutan, where GRIFFITH found it, and the Nango 
Mountains, where it was found by I. D. Hooker in 1848; 
the only foundation for the report that its zone of distri- 
bution extends to the source of the Kosi is the statements 
of the natives. The whole zone is situated within the 
Himalayas, where it was first found at a height of from 1800 m.
