THE NEWER EVERGREEN ORNAMENTAL TREES. 507 
cedar boughs, but was destroyed by the severe weather of ’55-6. 
At Elizabethtown, N. J., there are specimens five feet high, 
and, it is reported to us, as nearly hardy there. At Washington, 
and on Long Island it has not been sufficiently tested to be 
pronounced upon. The only unqualified return of entire suc- 
cess is from Augusta, Ga., where it stands admirably and 
becomes one of their most lovely evergreens. 
L. Doniana (Don’s arbor vitas)— even more than the pre- 
ceding resembles an arbor vitae, and is more 
^Thuja Doniana. generally known and sold as a Thuja than a 
Libocedrus ; it has the appearance of a most 
exquisite fern, being of a peculiarly soft yellowish green, and 
most delicate habit. There is no hope, we fear, of acclimatizing 
this beautiful variety, except, perhaps, in the Southern States ; 
but nothing can well be prettier or more attractive than this 
and the preceding variety (A. Chiliensis ), grown in pots or tubs. 
L. decurrens, the third and last variety, being more properly 
an arbor vitae, has been removed to that genus, we shall there- 
fore describe it under its appropriate head of Thuja. 
Picea. The Silver Fir. 
In contradistinction to Abies, the Spruce fir is derived from 
pix (pitch) — this variety producing an abundance of resin, and 
having their cones erect and nearly cylindrical, while the cones 
of the Abies (Spruce fir) are pendant and persistent for a long 
time. They are found in Europe, Asia, and North America 
and are, we believe, without exception perfectly hardy in the 
middle and northern portions of the United States, and a very 
great addition to our ornamental evergreens. 
P. amabilis (the lovely Silver fir) — one of the latest addi- 
tions to this tribe of plants, still rare and very 
Sy ™\ . costly. There are no plants of any size in 
P. lasiocarpa. J 1 J 
Pinus lasiocarpa. his country. It stands well at Beach Clyffe, 
the residence of Mr. Kane, at Newport, and 
also at Flushing, and we presume it may prove hardy at Boston. 
It is a magnificent tree in its native forests on the mountains 
of Northern California, reaching an altitude of two hundred
