 soft, close grained and resinous, esteemed for its durability, used for 

 building purposes as well as for cheaper grades of furniture. The seeds 

 are edible. Planted in Europe and America as an ornamental tree. The 

 seeds are sold in the markets, esteemed as a delicacy. 



Pinus bungeana Zuccarini. 

 White Bark Pine. (Bai Tsung) 



Tree 5-20 m. tall, sometimes divided into several stems. Bark dark 

 brown, scaling off into thin, irregular flakes, exposing the chalky white 

 inner bark. On old trees the bark becomes conspicuously white by 

 the flaking off of outside layers. Branches long and slender; branchlets 

 glabrous, gray-green. Leaves 6-10 cm. long, in bundles of 3's, rigid, 

 acute, light green, edges serrulate; sheath early diciduous. Staminate 

 flowers in loose spikes, 10 cm. long. Cones solitary or in pairs, almost 

 sessile, subterminal or pseudolateral, short ovate, 5-7 cm. long. Scales 

 yellow or yellow-brown, the apophysis with a transverse ridge at the 

 upper margin and a pointed, recurved umbo. Seeds brownish, with a 

 short, ineffective, loosely attached wing which sometimes remains in the 

 cone after the seed has fallen. Seeds ovate, about 9-13 mm. long. 



This pine is planted in temple grounds and courtyards, and is rarely 

 seen in a wild state. There are indications that this tree once formed 

 extensive forests. In the temple oi Tieh Ta Tsze, near Peking, is a 

 celebrated tree of this species named by the Emperor Chien Lung, ''Chiu 

 Lung Tsung " — the Pine of the Nine Dragons. Pinus bungeana is a slow 

 growing tree, with coarse, brittle wood. The white bark is distinctively 

 conspicuous and ornamental. This pine has a tendency to branch into 

 several stems which add to its decorative value.
