to 8,000 feet. In this country the tree is quite hardy, and makes a graceful 

 symmetrical specimen. 



Japan, like America, has sent us the handsomest Dogwoods or Cornels, 

 and there is reason to believe there is still something in this way to be 

 obtained from China, where it is more than probable all those species first 

 found in Japan are endemic. 



Cornus macrophylla, said to be synonymous with Cornus brachy- 

 poda, is a handsome, graceful tree, and flowers well in England, though its 

 cultivation in America has hitherto not met with success. Professor 

 Sargent holds it to be one of the most beautiful of all Cornels, an opinion 

 which can be endorsed from experience of the tree in this country. The 

 pointed leaves are dark green on the upper surface, almost white beneath, 

 borne thickly on branches at right angles to the main stem, forming flat 

 tiers of foliage. It flowers with great freedom — as with many deciduous 

 flowering Eastern trees in this country— every other year, unable 

 apparently to annually sustain such an exhausting effort (fig. 193). 



Under the name of Cornus brachypoda, my firm has a handsome 

 Dogwood, some 15 feet high, clearly distinct from the above in several 

 ways, but botanical authorities have difficulty in, as yet, determining its 

 exact position in the family. Of this undetermined species a variegated 

 form is unusually attractive. 



Of the behaviour of Cornus Kousa under cultivation too much cannot 

 be said. Though possibly its blossoms are individually not so large nor 

 so handsome as those of the American Cornus florida, it succeeds 

 on the whole better. It flowers freely, and has proved a striking and 

 valuable addition to the deciduous trees worthy of a place in our gardens 

 (fig. 194). 



Clethra barbinervis (C. canesccns), a beautiful small tree found all 

 through the Far East from Java to Corea, grows well and produces freely in 

 the early autumn its white-panicled racemes, often a foot in length. 



The nearly allied Enkianthus campanulatus, much esteemed in Japan 

 for its quaint beauty, flowers freely when left undisturbed in a sheltered 

 corner. 



Most of the Viburnums are well known, but the handsome Viburnum 

 dilatatum should not be overlooked, and Viburnum tomcntosum Mariesii 

 (fig. 195), allied to Viburnum plicatum, from which it differs in its more 

 graceful habit, its more hairy leaves, and in its sterile flowers being con- 

 fined to the outer part of the inflorescence, is an unusually handsome shrub. 



Styrax japonicum and Styrax Obassia are becoming known and are 

 amongst the most ornamental of any trees found in British gardens. 

 Though in the first-named the large dark green foliage of Styrax Obassia 

 is missing, ample compensation is afforded by the extraordinary profusion 

 with which the myriads of white bell-shaped flowers are produced. In 

 Japan Styrax Obassia is certainly seen to greater advantage than in this 

 country, its leaves often attaining a size of ten inches in diameter and 

 blooming with greater freedom than in our gardens. On the other hand, 

 Styrax japonicum is as much at home and as beautiful here as in China or 

 Japan. In Surrey it seeds freely, the seed germinating in one or two 

 years, though a large proportion lies three years before showing signs of 

 life.
