Specific Character .—Arbor monoecia excelsa, coma pyramidato-conica, ramis horizontalibus vel pen- 
dentibus foliosis, foliis imbricatis patentibus, lanceolatis acutis pungentibus, subtus haud carinatis, viridibus, 
strobilis magnis depresso-globosis, squamis acumine incurvato, seminibus cuneatis. Plabitat in montibus 
Chilensibus australibus, inter 35-50 lat. austr. 
A lofty monoecious tree, varying in height from 40 to 150 feet, 12 feet in girth, and reaching as high 
as 40 or 50 feet in the male, and 150 feet in the female. Stem straight. Bark of the old trees nearly a 
foot in thickness, of two layers, each 5 or 6 inches deep. The outer, like cork, 
but resinous ; the inner, spongy and resinous. Branches verticillated, usually in 
fives to eights, the lower ones horizontal or drooping, the upper ones more 
or less erect, the branchlets covered with leaves for many years (fig. 1). Leaves 
(fig. 2 upper and fig. 3 under side) ovate-lanceolate, growing in spiral whorls, 
very stiff, rigid, and sharp-pointed; slightly con¬ 
cave above, smooth, shining, and green on both 
sides, not keeled below; closely covered on both 
sides with rows of stomates, varying in number 
according to the size of the leaf, but usually 
about 100. A cross section of the leaf shews 
that resin canals and bundles of fibres are dis¬ 
tributed at nearly equal distances across the leaf, Fig. 2.—Upper Surface 
of* j 
as shewn magnified in fig. 4. The resin canals 
vary in number from 10 to 20 or thereby. They are easily distinguished by being surrounded by a circlet 
of cells. The leaf is surrounded by a well marked hypoderm under the epidermis. Fig. 5 is a more highly
