196 TREES OF THE NORTHERN UNITED STATES 
pressed, of a very dark, rich green colc 
very slightly glaucous, without tubere! 
on the back. Cones small, globular, so 
tary, with a fine, whitish bloom; scales 
rough and terminating in a sharp straig 
point. Tree 100 ft. high in Alaska, a 
would make a fine cultivated tree f 
this region if it could stand our hot, d 
summers. 
3. Chameecy paris Lawsoniana, Pai 
(Lawson’s Cypress.) Leaves small, de 
C. Nutkensis. green, with a whitish margin when youn 
forming with the twigs feathery-like, flat spray of a bluish-gre 
color; leaves usually with a gland on the back. Cones scarcely 
in. in diameter, of 8 to 10 scales. A mag- 
nificent tree in California, and where it 
is hardy (in rather moist soil, New-York 
and south) it forms one of our best eul- 
tivated evergreens. The leading shoot 
when young is pendulous. 
4, Chamecy paris (Retinéspora) ob- 
tusa, Endl. (JAPANESE ARBOR-VITZ.) 
Leaves scale-formed, obtuse, closely ap- 
pressed and very persistent. Cones of 
8 or 10 hard, light brown, wedge-shaped 
seales, Beautiful small trees or generally 
shrubs (in this country), of a score of 
named varieties of many colors and forms of plant and foliage. 
There are probably a number of species of Japanese and Chine 
Chamecyparis (Retinospora), but t 
their size, hardiness, and origin ha 
been more fully determined, it wou 
be impossible to make an entire 
satisfactory list for such a wo 
as this. Figures are given of t 
common, so-called, species cultivs 
ed in this country; under each 
these, several varieties are sold | 
7 the nurserymen. The three twi 
of Retinospora squarrosa were + 
taken from a single branch; tk 
shows how impossible it is to dete 
C. Lawsoniana.
