glabrous or glabrescent; winter-buds dark brown, ovoid or obtusish: leaves 

 compressed, acutish or obtusely mucronulate, 3^-^ inch long, with 2 broad 

 white bands above, green and keeled beneatli: cones cylindric-oblong, 3-4 

 inches long; scales rhombic, narrowed toward the truncate or emarginate 

 erose apex; bracts linear-oblong, obtuse, 4-5 times shorter than scale. Western 

 China. — Introduced in 1910 by E. H. Wilson to the Arnold Arboretum where 

 it has, like the two preceding species, proved hardy only in sheltered positions. 

 All three species will probably be very ornamental in suitable localities, but 

 the plants have not yet attained sufficient size to allow a definite opinion. 



A closelj' related species is P. brachytyla, Fritz. {P. pachyclada, Patsclike). 

 Tree to 80 feet tall; bark dark brown, deeply fissured; branchlets nearly 

 glabrous, with prominent pulvini: leaves about 3 o inch long: cones 3-4 inches 

 long, with obovate scales entire at the margin. Central China. — Introduced 

 by E. H. Wilson to England in 1901. 



30. P. Omorika, Bolle (Pinus Omorika, 

 Pancic). Servian S. Fig. 76. Tree to 100 

 feet tall or higher, with rather short spread- 

 ing and ascending branches and short pendent 

 branchlets forming a 

 narrow pyramidal head; 

 bark brown, separating 

 into thin plates; branch- 

 lets brown, pubescent; 

 winter-buds dark brown, 



not resinous: leaves compressed, obtuse and 

 mucronulate, dark green and shining below, 

 with whitish bands above, Yz~Y2 inch long, 

 keeled on both sides: flowers purple: cones 

 ovoid-oblong, cinnamon-brown, glossy, 

 1/^-23^ inches long; scales almost orbicular, very convex, with finely 

 denticulate margin. Southeastern Europe. — Discovered in Serbia in 1872 

 and introduced into cultivation about 1880. Hardy as far north as southern 

 Ontario and New England and possibly farther north. A desirable orna- 

 mental tree of dense narrow-pyramidal habit when young; one of the best 

 spruces for the northeastern States. 



31. P. Breweriana, Wats. Tree 80-120 feet high, with the branches at 

 the top slightly ascending, the lower ones horizontal or pendulous, with 

 whip-like pendulous branchlets often 7 to 8 feet long, furnished with similar 

 slender lateral branchlets; branchlets reddish-brown, pubescent; winter-buds 

 conical, chestnut-brown: leaves radially spreading, straight or slightly curved, 

 obtuse, rounded and dark green at the lower surface, almost flat and with 

 white bands above, ^4-1 inch long: staminate flowers purple: cones oblong, 



7G. Picea Omorika.
