material to hand. It must finally be stated, that in the 
analysis of the cone-scales and bracts of L. laricina, as 
given by Britton & Brown, the bracts have exactly the 
form described by WIGHT for L. alaskensis (Britton & 
Brown: Ill. Fl. 2nd. Ed. I. 1913, p. 60). Therefore L. alas- 
kensis, WIGHT, cannot be maintained, either as a species 
or variety; it can only be regarded as a form of growth, 
influenced by inclement external conditions; a similar form 
will presumably be found further east- a

wards on the extreme northerly limit for 
the area of L. laricina. We have material 
from Fort Churchill, Hudson Bay, which 
supports this supposition. 
Finally, it should be adduced for 
the sake of completeness, that HENRY

wrongly classifies L. alaskensis, with  (DuRoi) Koch. Cones

old Arborets in England, where it 
has long been cultivated, but has never become 
common. In Denmark it is stated as planted in the 
Arboretum at Aalholm in 1832 (WeEırsacH: Notes, Bibl. 
Hort. Bot. Haun.). A tree at Bellevue near Præstø which 
still exist probably dates from the same time and was in 
1924 24,5 m. high with a girth of 1,5 m. (1,3 m. above the 
ground). The oldest mention of American Larch in forest 
culture in Denmark from about the year 1800 (OPPERMANN, 
1923) we regard as not applying to L. laricina, but to
