FLOWERING TREES AND SHRUBS 49 



Corylus (Corylaceae). 



CORYLUS AVELLANA PURPUREA. Purple Hazel. This has 

 large leaves of a rich purple colour, with crimson flowers, 

 and is a very distinct and ornamental plant for the 

 shrubbery border. It should be cut down annually if 

 large leaves are desired. 



C. AVELLANA AUREA has rich golden foliage, while 

 C. AVELLANA LACTNIATA has the leaves neatly cut, and 

 C. AVELLANA PENDULA is a weeping variety, but of no 

 particular value for ornamental planting. 



C. COLURNA. Constantinople Hazel. Turkey, 1665. 

 This is the largest and most ornamental of the family, 

 and is mentioned here on account of the showy catkins 

 with which the tree is well supplied. When thickly 

 produced, as they usually are on established speci- 

 mens, these long catkins have a most effective and 

 pleasing appearance, and tend to render the tree one 

 of the most distinct in cultivation. Under favourable 

 circumstances, such as when growing in a sweet and 

 rather rich brown loam, it attains to fully 60 feet in 

 height, and is of neat shape, from the branches being 

 arranged horizontally, or nearly so. Even in a young 

 state the Constantinople Hazel is readily distinguished 

 from the common English species, by the softer and 

 more angular leaves, and by the whitish bark which 

 comes off in long* strips. The stipules, too, form an 

 unerring guide to its identity, they being long, linear, 

 and recurved. All the Hazels succeed in rich, dampish 

 loam. 



Cotoneaster (Rosaceae), 



COTONEASTER BACiLLARis. Nepaul, 1841. A large-grow- 

 ing deciduous species, and one of the few members of the 

 family that is more ornamental when in flower than in fruit. 

 It is of bold, portly, upright growth, and sends up shoots
