of being a low tree, it is superior m size to
the black spruce, as it general y grows in
richer soil ; and that the wood is reddish,
instead of being white. In Lawson s Manual,
it is stated that A. rùbra differs eraentially
both from A. nigra and A. a ba in all its
parts I and particularly m its leaves, which
are more slender and sharper-pointed than
in either of these species.

Varieties. Dr. Royle observes that the leaves in his figure are much narrower
than those of A. Smith/™« in Wallich’s figure; and that the plants may
probably be different species or varieties. Judging from the leaves, the tree
in the Horticultural Society’s Garden appears to he Dr. Royle’s tree.
The rate of growth of this tree in British gardens is almost as rapid as that
ot the common spruce, to which it bears a very close resemblance, but the
leaves are longer and paler. It is readily propagated by cuttings, and abundiMice
of seeds have lately been imported. Some doubts having been expressed as to
whether this plant is the A. Smithia'ji« of Wallich (see Bot. Beg for 1841)
but none as to its being the P. Khutrow of Royle, we have in this edition
preferred the latter name.

Varieties Cones of different sizes, and somewhat different in the shape and
size of the reales, have been sent home by Hartweg and others ; because,
doubtless this species of spruce is liable to vary as well as every other ■
and the .slightest variation in any species of plant which is comparatively
rare is immediately constituted a named variety. Only one variety, that we
nave heard of, deserves notice.
^ fazifolia. — Stem and side branches straight ; while in A.
Douglasii they are always,
when young, more or less in
a zigzag direction, though
they become eventiiaily
straight. Leaves twice the
length of those of A. Douglas
«, and of a much deeper
green. Fig. 1932. is from a
specimen and a sketch received
from Mr. M‘Nab,
showing the foliage and
manner of branching of A.

name in the Chiswick Garden
