Keteleeria ^475 



plants survived in England, but a fine specimen ^ is growing in Rovelli's nursery at 

 Pallanza, which measured 55 ft. by 8 ft. in 1909. This tree produces seed freely, 

 from which numerous plants have been raised since 1884. Mr. Rovelli states that 

 they are very difficult to transplant; and we know of none which have as yet 

 attained any size in England. (A. H.)

A tree, attaining^ in China 100 ft. in height and 16 ft. in gii'th. Young branch- 

 lets slender, with short stiff erect hairs. Buds as in K. Fortunei, but with scales 

 not keeled on the back. Leaves on adult trees similar to those of that species, but 

 slightly larger, with a wider prominent midrib beneath, on each side of which are nine 

 lines of stomata. 



Leaves on young plants \\ in. long, \ in. broad, tapering to an acuminate spine- 

 tipped apex ; lower surface with a broad green midrib, elevated in the central line as 

 a narrow ridge, two stomatic bands, each of eight to nine lines, and two marginal 

 green bands, near the edge of each of which is a linear longitudinal groove. 



Cones sub-sessile or stalked, nearly cylindrical, 6 to 8 in. long, 2 in. in diameter, 

 brown when ripe : scales about i in. long and \ in. wide, ovate, with a rounded or 

 slightly contracted truncate apex, which is inflexed ; concave internally from side to 

 side ; outer surface minutely pubescent towards the base : bract \ in. long, with an 

 oblong claw ending in a denticulate lamina, scarcely broader than the claw, and tipped 

 with an acuminate point. Seeds not extending quite to the apex or lateral margins 

 of the scale. 



This species, which was discovered by Pere David in 1869, is widely distributed 

 throughout the interior of China, occurring in the provinces of Shensi, Hupeh, Szech- 

 wan, and Yunnan ; and has recently been found in the mountains of Formosa. In 

 China it is a tree of lower elevations than Abies or Picea, and forms woods in a 

 warm climate on dry hills at about 2000 to 4000 ft. altitude in western Hupeh, and 



1 Figured in Gard. Chron. xxv. 428, fig. 83 (18S6). According to Carriere, Rev. ffort. 1887, p. 211, it was planted in 

 1859. Carriere adds some interesting details of this species, which he states can be multiplied, but with difficulty, by cuttings 

 and layers. 



2 I measured a tree of this size in the Wushan district, north of the Yangtse in eastern Szechwan, in 18S8.
