 Description, c}c. A tree, in general appearance and size, like A. imbricata ; 

 but much more loose and spreading. Branches numerous, leafy, approximate, 

 sometimes almost verticillate ; branchlets, in the young trees, flexible, spread-

 Leaves lanceolate, mucronate, quite entire, a little car- 

 tilaginous, much more loose, and three times thinner 

 than in A. imbricata ; somewhat pliant, smooth ; con- 

 cave above, light green, and shining ; beneath glaucous

 on both sides, but especially on the lower, with many 

 dotted lines ; scattered on the young tree, spreading,

 broad. Male catkins not yet known. Female, 

 roundish-ovate, solitary on the apex of the branches, 

 sessile, similar in size and appearance to the heads of 

 flowers ofZMpsacus sylvestris; scales thick, compressed, wedge-shaped-oblong, 

 quadrangular, of a firm corky substance, closely placed together above a conico- 

 cylindrical receptacle, each terminated by a lanceolate, acute, recurved ap-
