PICEA ALCOCKIANA (Carriere). 



Gardeners' Chronicle Vol. XIII. p. 212 (1880). 

 Veitch's Man. Conif. ed. 2, p. 429 (1900). 



A TREE attaining a height of 70 feet or more with greyish-brown 

 scaly bark. Branches stout, horizontal or depressed. 



Branchlets pale brown or almost white, pubescent. Buds ovoid 

 with obtuse closely imbricated scales. Leaves persisting five to seven 

 years, crowded, linear, quadrangular in section, mucronate, J - f inch 

 long, with lines of stomata on the ventral surfaces, and broad white 

 bands on the dorsal surfaces. 



Cones ovoid-cylindric, 3 - 4 inches long and 1 - 1 inches in dia- 

 meter when closed ; scales broadly obovate-cuneate ; seed-wing obovate- 

 oblong, two-thirds as long as the scale. 



Picea Alcockiana occurs only in the mountains of central Japan, 

 where it was discovered on Fuji-Yama by John Gould Veitch in 

 company with Sir Rutherford Alcock and introduced in 1861. It 

 occurs at an altitude of 6,000 to 7,500 feet. 



This tree was formerly confused with Picea ojanensis owing to 

 seeds of the two species having been distributed under one name. 

 It is extremely rare in cultivation. 



Picea Alcockiana was added to the Bayfordbury collection in 

 1908. The cones photographed were obtained from a tree at Pen- 

 carrow, Cornwall.
