A tree, usually thirty or forty, but occasionally seventy feet in height, with a trunk from two to 
four feet in diameter, and horizontal branches forming a narrow pyramidal or occasionally a broad flat 
head. The bark on old trunks is thin and dark red-brown, and separates freely into long shreds one 
or two inches in width, which often remain hanging upon it for years; on young trunks and on the 
branches it breaks into large irregular thin scales, which, in falling, disclose the bright red inner bark. 
The branchlets are stout, and after the leaves have fallen are covered with smooth close thin light red- 
brown bark, more or less covered with a glaucous bloom. The leaves are ovate, acute, thickened, 
carinate and eglandular or occasionally obscurely glandular-pitted on the back, pale glaucous green, 
closely appressed or often slightly spreading, and about an eighth of an inch in length; dying usually 
during the second season, they become light red-brown and glaucous, and remain on the branches for 
two or three years longer. The staminate flowers are oblong, obtuse, nearly a quarter of an inch in 
length, and composed of six or eight stamens, with broadly ovate acute yellow connectives slightly 
erose on the margins. The pistillate flowers are unknown. The fruit is subglobose, slightly puberu- 
lous, about an inch in diameter, dark red-brown, covered with a thick glaucous bloom, and raised on a 
stout peduncle from one quarter to one third of an inch in length, with six, or occasionally eight scales, 
furnished with stout cylindrical pointed often incurved prominent bosses. The seeds vary in shape 
from oblong to nearly triangular, and from one sixteenth to nearly one eighth of an inch in length, and 
are dark red-brown, with thin narrow wings. 
Cupressus Arizonica inhabits the mountains of central, eastern, and southern Arizona, often 
constituting, usually on northern slopes, almost pure forests of considerable extent, at elevations of from 
five to eight thousand feet above the sea, and also the mountains of northern Sonora and Chihuahua. 
Local in its distribution in Arizona, it forms a grove of several thousand trees at the natural bridge 
over Pine Creek, a tributary of the Verde River near Payson, in central Arizona ;’ 
Santa Rita, Santa Catalina, and Chiracahua Mountains in the southern part of the territory, and on the 
San Francisco Mountains in the extreme eastern part, where it was discovered in the neighborhood 
of the town of Clifton on September 1, 1880, by Professor Edward L. Greene;* and on the mountain 
ranges north of Mt. Graham it is common, and forms extensive forests. 
The wood of Cupressus Arizonica is light, soft, close-grained, and easily worked. It is gray, 
often faintly streaked with yellow, with thick light yellow sapwood, and contains broad conspicuous 
bands of small summer-cells and numerous obscure medullary rays. The specific gravity of the 
absolutely dry wood is 0.4843, a cubic foot weighing 30.18 pounds. 
Cupressus Arizonica was introduced into European gardens in 1882 through the agency of the 
Arnold Arboretum, and has proved hardy in England.’
