36 CHINESE ECONOMIC TREES 



Native of N. E. China, elsewhere cultivated. Introduced into Japan. 

 The Poh shu of the classics is referable to this species. In bygone days 

 the tree distinguished the gardens of the princes and sheltered the tombs. 

 of rulers. To-day it is most commonly met with in gardens and burying 

 grounds. Throughout the New Year festivities, sprays of this fragrant 

 evergreen are used to symbolize long life and happiness. The fruit, 

 leaves and inner bark all have medicinal uses. 



Propagated by seeds. The number of seeds per pound is about 

 18,600, germination is rapid, most of the seeds coming up betv?een 10 

 and 25 days. 



Thuja sutchuenensis Franchet. 



A small tree in Eastern Szechuan characterized by thin, scaly, nearly 

 glandless leaves or flattened branchlets, thin, leathery cones with 8 

 scales, somewhat thickened at the apex, and winged seeds produced only 

 by the middle 2 or 3 pairs of scales. 



FOKIENIA 



Trees, evergreen. Leaves small, scale-like on flattened, frond-like 

 branch systems which may be described as tripinnately divided. The 

 leaves are in 4 ranks, the lateral pairs narrowly keeled or clasping, the 

 facial leaves flattened, acute or obtuse, with the bases narrowed or crowded 

 by the lower parts of the lateral leaves. On young shoots the branchlets 

 appear particularly flattened, the leaves are much larger (sometimes 8 

 mm. long), the lateral paira with conspicuously long, free, sharp points 

 and often marked on the under surface by conspicuous longitudinal 

 glaucous areas caused by stomata. The foliage has a strong resemblance 

 to Libocedrus macrolepis. The flowers are imperfectly known. 



Female flower terminal, composed of 6 to 8 pairs of opposite, 

 decussate, blunt-pointed scales, each scale with 2 ovules. Cones are said 

 to ripen in the 2nd year. They are globular in general form, composed 

 of 12 to 16 woody, peltate scales, each clavate or cuneate in shape, 

 expanded into a mainly 2-lobed shield or apophysis with a minute mucro 

 in the depressed center. 



Seeds 2 to each seed-bearing scale, about 4 mm. long, 3 or 4 sided, 

 flattened at the base and provided with 2 thin wings unequal in size.
