Ti2 PICEH, OR SPRUCE TREES 
past day, when they were first sent over to England. 
There is this wide difference between them, that the 
Alcockiana is a four-sided leaf with stomata more or 
less on all surfaces. The Hondoensis and Ajanensis 
(its near affinity) are flat-leaved trees, with stomata 
only on one side. 
The leaves of Alcockiana are stiff-curved with a 
cartilaginous point, the leaves of the others are 
blunter. 
The branchlets of the Alcockiana show pubescence 
in the grooves of the branchlets. The Hondoensis 
and Ajanensis do not. 
The resemblance between them and the Hon- 
doensis, then, is reduced to a mere nominal confusion, 
due to no similarities of any natural construction. 
The Alcockiana is not recommended by the faculty 
as a ‘‘ thing of beauty or a joy for ever,” to anyone 
who wishes to plant with these desirable objects 
in view. 
Note 1.—The latest ‘description of this tree comes 
from E. H. Wilson, in an account of it published in 
the Arnold Arboretum publication, 1916, and entitled 
Conifers and Taxads in Japan. 
The shoots he describes as at times quite glabrous, 
but on adult trees and their principal shoots pubes- 
cent. 
The leaves he describes as rhombic (quadrilateral) 
in section, of a bluish-green colour, oblique at apex, 
with small cartilaginous points. They and the cones 
are much the same as described by other authorities, 
from whom the details, as they appear in table, p. 280, 
are collected. 
Note 2.—There are two varieties of the P. Bicolor— 
Acicularis and Reflexa—called attention to in The 
Gardener’s Chronicle, August 14th, 1915, by the great 
Japanese authorities, Shirasawa and Royama. Both 
have slightly different cone scale features, but are
