CORYLOPSIS CORYLUS 399 



red-brown, distinctly protruded. Calyx lobes short, rounded, hairy. Fruit 

 at first densely hairy, about in. long. 



Introduced in 1900 by Wilson from Western Hupeh, China, and first raised 

 in the Coombe Wood nursery, where it has flowered each April for some 

 years past. From C. sinensis it differs in its glabrous leaves and protruded 

 red-brown anthers. 



C. WlLLMOTTLE, Rehder and Wilson. 



A deciduous shrub, 6 to 12 ft. high; young shoots brown, not downy, but 

 with numerous small lenticels; winter buds pale shining green, stalked. 

 Leaves 2 to 4 ins. long, oval, obovate or roundish ovate; truncate or slightly 

 heart-shaped at the base, short-pointed; dark bright green and smooth above; 

 rather glaucous beneatn and downy, especially on the midrib and veins; 

 veins in seven to ten pairs. Flowers soft greenish yellow and fragrant. 

 Calyx, ovary, and fruit smooth. 



Native of W. Szechuen, China; introduced by Wilson in 1909; first shown 

 in flower at the Horticultural Hall, 5th March 1912, as "C. multiflora." The 

 true plant of that name does not appear to be in cultivation. 



C. WlLSONI, Hemsley. 



A shrub or small tree, the branchlets at first furnished with stellate down. 

 Leaves ovate or obovate ; 3 to 5 ins. long, i^ to 3 ins. wide ; abruptly con- 

 tracted at the apex to a long narrow point, the base heart-shaped, the margin 

 edged with bristle-like teeth ; glaucous beneath, and smooth on both sides 

 when mature ; stalk f to i^ ins. long. Flower-spike 2 to 3 ins. long, the basal 

 or stipular bracts roundish ovate, f in. long, silky hairy on both sides ; flower 

 bracts similar except for being smaller. Petals \ in. long, narrowly obovate, 

 primrose-yellow. Fruits not downy. 



Discovered and introduced to the Coombe Wood nursery in 1900. It 

 differs from all other cultivated Corylopsis in having the lower bracts hairy 

 outside. In many other respects it resembles C. Veitchiana. 



CORYLUS. HAZEL, FILBERT. CORYLACE.E. 



Corylus belongs to the group of trees and shrubs with the male 

 flowers in slender, pendulous catkins, and the fruit (a nut) enclosed 

 wholly or in part by one or more bracts forming an involucre (husk). Its 

 nearest allies are Ostrya, Carpinus, and Ostryopsis, the four constituting 

 the natural order. 



The hazels are well-marked deciduous trees and shrubs, with alternate, 

 toothed leaves. Male and female flowers are borne on the same plant, 

 the male catkins usually in clusters of two to five. Female flowers 

 scarcely discernible individually, the visible part of each being two red 

 stigmas projecting from the flower-bud ; the catkin bears several flowers 

 in the axils of its upper scales. The seed is enclosed by a hard shell, 

 which is itself set in a husk rather fleshy at the base, with coarsely toothed 

 or lobed margins. 



In gardens the hazels are chiefly known as bearing edible nuts, viz., 

 cobnuts and filberts. The common species have not much to attract 

 planters for ornament alone, although in February when they are freely 

 hung with the graceful, slender, yellow, male catkins, they have that
