Adams. — Acorns and Leaves of Oaks grown at Greendale. 225 



Quercus cinerea Michx. 



The upland willow oak was early introduced to New Zealand, and 

 trees have borne acorns for many years in Canterbury. 



Quercus coccinea Wangenh. (the Scarlet Oak). 



This is a valuable tree, furnishing the " quercitrin," so highly valued as 

 a yellow dye and a tanning-material. In recent years largely planted in 

 New Zealand for its fine autumn foliage. 



Quercus cuspidata Thunb. 



This is a very desirable evergreen tree from Japan. It has flowered 

 here several years, but not yet borne fruit. In Japan the acorns are con- 

 sidered good to eat. Planted, 1893. 



Quercus dentata Thunb. 



This has probably the finest foliage of any oak. Although not so large 

 as those of Q. macrocarpa, the leaves resist the wind much better, and are 

 retained on the tree until the spring growth commences. 



Quercus dilatata Lindl. 



A tree of this species in the Botanical Gardens, Christchurch, is now 

 57 ft. high and 6 ft. in girth. Trees raised at Greendale from acorns received 

 from Darjeeling in 1904 are 10 ft. to 12 ft. high, and have successfully 

 withstood the winters. 



Quercus dumosa Nutt. (the Scrub Oak). 



This has very small holly-like leaves, which are probably the smallest 

 leaves of any oak. Trees only 8 ft. high have borne acorns at Greendale. 

 A native of California. 



Quercus esculus L. (the Italian Oak). 



This is said to be a handsome tree ; only small plants are growing here. 

 The " Index Kewensis " considers it sjnionymous with Q. Gerris. 



Quercus falcata Michx. 



An American tree, there called the " Spanish oak." The wood is not 

 much valued, but the bark is reputed to be of great value for tanning. 

 The tree is growing well at Greendale. 



Quercus Garrayana Dougl. (the Oregon Oak). 



This is a native of California. It is making very slow progress here. 



Quercus glauca Thunb. 



A beautiful evergreen tree from Japan, not hardy in England. It was 

 damaged by frost at Greendale a few years ago. 



Quercus Ilex L. (the Evergreen Oak). 



This evergreen oak was early introduced, and is growing well throughout 

 New Zealand ; there are large trees at Riccarton, the Three Kings College, 

 Auckland, and many other places.
