Keteleeria davidiana Beissner. 



Tree sometimes 35 m. tall, with dark gray, irregularly fissured bark. 

 Young branches slender, gray, glabrous or tomentose, or sometimes with 

 short stiff hairs. Leaves 2-5 cm. long, rounded, notched at the apex, 

 glossy green above, with stomatiferous lines and 2 green bands beneath, 

 midrib raised on both sides. Cones cylindrical, oblong, on spur-like 

 lateral branchlets, 5-20 cm. long, averaging 10-15 cm. long, reddish 

 when young, turning green and finally brown at maturity. Cones scale 

 ovate with a rounded or slightly truncated and reflexed apex, exposing 

 the tip of the wings. 



Shensi, Hupeh, Szechuan, Yunnan. 



This is the most widely distributed species in China, occurring at an 

 elevation somewhat less than that occupied by the firs and spruces. In 

 a wild state it shows considerable variation in leaf and cone. The wood 

 is soft, close grained, light, resinous and easily worked. It is used for 

 the construction of houses. 



Keteleeria evelyniana Masters may be identical with or at most only 

 a form of the above. 



Keteleeria fortunei Carriere. 



Tree to 30 m. tall with thick, rugged bark and spreading, horizontal 

 branches. Branchlets glabrous, orange-red. Buds small, ovoid, 

 orange-brown. Leaves appearing 2 ranked by the twisting of their 

 petioles, linear, rigid, mucronate or spine-tipped, dark shiny green, 

 keeled above with 2 stomatiferous lines beneath; 2.5-3 cm. long. Cones 

 variable in size, ovoid or ovoid-cylindric ; scales suborbicular ; bracts 

 half as long as the scales, mucronate tipped. Cones at first purplish, 

 becoming brown with age. Seeds angular and wedge-shaped with a 

 relatively broad, rounded, oblong wing. 



S. E. China: Hongkong, Yunnan, Fukien. Characterized by orange- 

 red, glabrous branchlets and purplish cones which become brownish at 

 maturity. 



The cones of this species are smaller and more globose than those 

 of the preceding species.
