1220 PICEZ, OR SPRUCE TREES 
with regard to them be brought to a timely end, 
by the explorer, E. H. Wilson, who was making an 
expedition there in 1914.1. We will, as far as any 
reference goes to them here, run them in couples 
and treat them as one. 
The differences of their cones may be a help to the 
identification of the Japanese trees and the Sitka. 
From the many thousand specimens fallen from the 
Sitka, and that I have had before me, the cones have 
always been of.a uniform size, and that size is 2 in. 
long. 
Of the Japanese tree, and from cones sent me 
from that country, the Hondo and Ajan are con- 
siderably longer than the specimens of our home- 
grown Sitka, but the point of difference to note is 
that while the margins of the scales of the Sitka 
cones, are only minutely frayed in appearance, and 
even sometimes slightly wavy or entire, the Japanese 
representatives present torn and tattered appearance 
of margin with their jagged edges. The leaves of 
the Japanese, too, are shorter. 
This disposes of the list of the up-to-date naturalized 
Spruces which have made appearance in our islands, 
with the exception of the MorInpDoIDEs (now re- 
christened Spinulosa), a native of Sikkim. This tree 
has the appearance of a short-leaved Morinda, or 
Smithiana (Himalayan Weeping Spruce), and several 
we saw in a very promising condition have come to 
untimely ends, at even such climatically favoured 
situations as Castlewelan, County Down. 
1 E. H. Wilson’s ultimatum on this long-standing vexed question, 
after a careful investigation of the two trees in their native islands, 
Hondo and Hokkaido, during his 1914~16 expedition, gives out that 
they are one and the same tree, the Hondoensis and Ajanensis; and, 
moreover, that they are the only flat-leaved Spruce, so far found, 
existent in N,-E. Asia and Japan,
