Quercus I 3 2 9 



The above description applies to the Japanese form. The species is very 

 variable in the wild state in foliage, and several varieties have been described. In 

 Himalayan specimens the serrations of the leaves have long mucronate points. 



The following peculiar variety probably originated in Japanese gardens : 



Var. lacera, Matsumura, Shokubutsu Mei-I, 243 (1895). 



Quercus lacera, Blume, in Mus. Lugd. Bat. i. 306 (1850). 



Leaves obovate, ovate, or lanceolate, with the apex prolonged into a long 

 slender caudate acumen ; margin deeply lobed, each lobe ending in a long carti- 

 laginous point. 



There is a small plant of this variety in Kew Gardens, introduced in 1907 from 

 Yokohama. 



Quercus glauca is widely spread in eastern Asia, occurring in the Himalayas from 

 Kashmir to Bhutan at 3000 to 6000 ft., throughout the mountains of China, and in 

 Japan and Formosa. Sargent ' states that the acorns are eaten by the Japanese, and 

 are of considerable commercial importance. 



The Himalayan form was introduced in Loudon's time, as there were plants 

 about 10 ft. high at Kew, Chiswick, and Loddiges' nursery ; but none of these 

 appear to have survived. The only specimen which we have seen is a small tree 

 at Tortworth, probably of Japanese origin, which appears to be perfectly hardy, but 

 has never borne fruit, (A. H.)
