HAZEL 



embers glow in still air : no smell or exudation with heat. Solu- 

 tion colourless. 



Grain. Very fine, even, and dense though open : a compact, 

 solid wood. Surface bright to dull. 



Bark. I to i inches thick, rich, deep brown : deeply fissured 

 and scaling in long flakes which are seen to be clearly marked 

 off in the inner layers in vertical section : closely adherent, corky 

 but rather hard : many light-coloured sclerenchyma fibres. 



Uses, etc. Similar to those of the Common Hornbeam, a 

 valuable wood for turnery resembling Pear-tree wood. " Very 

 tenacious " (69). 



Authorities. Mathieu (69), p. 403. Wiesner (131), L. 13, 

 p. 890. 



Colour. Heart-wood light-red, pinkish to brown fading 

 gradually into the lighter sap-wood. 



Anatomical Characters. As those of O. virginica No. 193. 

 Transverse section differs inasmuch as the tree-like arrangement 

 is not so visible to good sight, the soft- tissue not being so white 

 and therefore does not show up without considerable magni- 

 fication. 



Tangential Section. The same feature provides a slight distinc- 

 tion as S-T appears as clearly hoary fringes to the loops, readily 

 visible to the unaided eye. 



Type specimens from a tree grown in the Royal Gardens, 

 Kew, sent to me by the kindness of Sir Wm. Th. Dyer. 



No. 195. HAZEL. Corylus avellana. Linn.

 none. Taste faintly astringent. Burns well and quietly : 

 embers glow in still air. Solution with water almost colourless.

Bark. About -fa inch thick with a shiny, brown skin readily 

 peeling off : grey when old : lenticels conspicuous. The rays

 gunpowder . . . not durable, very elastic. Usually confused 

 with Birch. Of small size.
