Cupressus 
nutkaensis 
160 ARBORETUM NOTES 
CONIFERZ. 
CUPRESSINEA. 
A native of the north-west coast of North 
America, first observed near Nootka Sound, in - 
49° North lat.; found-as far north as Sitkayeae 
north lat. 58°. Is said to grow into a tree 
1oo feet high. Here, it has not yet assumed the 
appearance of a tree, the trunk being concealed 
quite from the ground, by the densely growing 
branches and leafy shoots; its general form 
pyramidal, but not so upright and stiff as that of 
the common Cypress, or the Chinese Thuza. It 
is very handsome from its deep, rich glossy 
green colour, and the beautifully feathery or fern- 
like ramification of its young branches. It belongs 
to that section or subgenus of the Cypresses 
(made into the genus chamaecyparis by Spach and 
Parlatore) which by the flattened and pinnated 
form and arrangement of the leafy branches 
resembles the Thuias. In fact the Cypresses of 
this group have the branches and leaves of Thuia 
and the cones of Cupressus. To this group belong 
the Cupressus thuoides of Linnzus and _ the 
Cupressus lawsoniana of Murray, as well as 
the present one. This is generally known 
among cultivators by the name of Thuyopsis 
borealis; but in Parlatore’s monagraph of the 
Conifere* the genus Thuyopsis is restrictid to 
one species Thuia dolabatra (Thuia dolabatra of
