Postelsia 199 
dark reddish-brown, glaucous, with four to six 
scales, each furnished with a prominent, erect, 
pointed boss; seeds two to four on each scale, 
about 5 millimeters long, with large lateral wings. 
Southern Alaska to Oregon, mostly at high 
elevations in the Coast and Cascade Mountains. 
Common in southeastern Vancouver Island at 
elevations above one thousand feet. 
A tree of moderate size resembling Thuja 
plicata in foliage. The two can be readily dis- 
tinguished by the fruit, and with little difficulty 
bya sclose examination of the foliage: “Ihe 
branchlets of this tree are much less flattened 
than those of Thuja plicata, the leaves of the 
four ranks are more nearly alike in form, and 
all the leaves, especially those of the leading 
shoots, are more pointed than in that tree. Both 
species have aromatic foliage, but their odors are 
entirely different. The smell and taste of the 
fohage of this Cupressus approximate much 
more closely to some of the species of Juniper 
than to Thuja. 
The seedlings of this species, like those of 
Thuja plicata, have spreading acicular leaves
