102 Select T-la-ntsfor Industrial Culture 



Cornus mas, Linne. 



Europe, also Asia quite to Japan. This deciduous shrub or small 

 tree is deserving of attention, as from the fruits a very palatable pre- 

 serve can be prepared (Freyn). It answers also for hedge-growth. 



Cornus Nuttalli, Audubon. 



North- Western America. This is the largest of the genus, attain- 

 ing a height of 80 feet, with a stem 2 feet in diameter. One of the 

 most showy of Californian forest-trees. The wood is hard and close- 

 grained, similar to that of the preceding species. The natives use the 

 small twigs for making baskets (Dr. Gibbons). The white spring- 

 inflorescence is visible for miles ; in autumn again the scarlet fruit- 

 coloration becomes an ornament to the landscape (Prof. Bolander). 



Cortinarius cinnamomeus, Fries. 



Europe and Asia. This mushroom, together with C. violaceus 

 (Fries), is mentioned among numerous congeners by Drs. Badham and 

 Cooke as particularly eligible for the table. Dr. Planchon recom- 

 mends also C. turbinatus (Fries). 



Corylus Americana, Walter. 



Eastern North-America. Not tall ; easily naturalized by dissemina- 

 tion, but fruit small and hard-shelled (A. Gray). 



Corylus Avellana, Linne". 



Europe, Northern Africa, Northern and Middle Asia. The ordinary 

 Hazel, so well known for its filberts or cob-nut, one variety yielding 

 the Barcelona-nut. A tree attaining a height of 30 feet; wood elastic; 

 young shoots serving for hoops. The earliest flowering tree in north- 

 ern countries. Loudon's account also of this tree is extensive and 

 excellent. Chambers says, that generally about 100,000 worth of 

 hazel-nuts are annually imported into Britain. 



Corylus Colurna, Linne". (C. Bizantina, 1'Echise.) 



From Hungary to Greece and the Himalayas, there at from 5,500 

 to 10,000 feet elevation. The Constantinople-Nut Tree, the tallest 

 of hazels, attaining 60 feet in height, of rather quick growth. Hardy 

 at Christiania in Norway (Schuebeler). This, as well as the Nepal- 

 Hazel (Corylus ferox, Wallich) and the Japan-Hazel (C. heterophylla, 

 Fischer) might be naturalized in forest-gullies for their filberts. 



Corylus maxima, Miller. (<7. rubra, Borkhausen ; C. tubulosa, Willdenow ; 

 C. Lambertii, Loddiges.) 



Recorded as indigenous to Hungary and Istria by A. de Candolle, 

 who however places the species nearer to C. Americana. Prof. C. 

 Koch thinks, that it may have sprung from C. Avellana. It yields 

 the red filbert or Lambert-nut. 



Corylus Pontica, C. Koch. 



Caucasus. Taller than C. maxima. Fruit similar to the Barce- 

 lona-nut; much consumed in Constantinople (C. Koch); called also 

 Pontinian-nut.
