184 HAZEL 



former is at once distinguished by its more fusiform buds 

 and spiral scales; the latter by its fatter and more rounded 

 buds and glandular hairs. In the last resource i.e. if the 

 very different leaves, flowers and fruits are inaccessible 

 the wood of the Elms has large vessels in the spring wood 

 and tangential bands of parenchyma in the autumn wood, 

 both wanting in transverse sections of Hornbeam and 

 Hazel. 



There is still considerable difficulty about the various 

 sub-species or varieties of Elms, but U. campestris has the 

 twigs and buds practically smooth; while in U. montana 

 both are stiffly hairy. In both the bud-scales are uniformly 

 brown. In the var. effusa, the twigs are glabrous, but the 

 buds, which are sharp and hard pointed, have pale brown 

 scales with an almost black ciliated margin. 



(/3) Buds rounded-ovoid, obtuse, with several 

 broad glandular - ciliate scales, spirally 

 imbricate; twigs glandular, hairy. 



Corylus Avellana, L. Hazel (Fig. 92). The buds are 

 somewhat compressed, hardly displaced to one side of 

 the projecting leaf-scar ; bud-scales tawny or greenish to 

 brownish, and fringed with reddish glandular hairs and 

 cilia; the pedicel of the male catkins, usually discoverable 

 in winter, particularly glandular. Twigs olive-brown, the 

 lenticels obscure, but visible on the smooth brown branches. 

 The female flowers are in buds, very similar to the ordinary 

 ones, but fatter, and the crimson stigmas protrude in early 

 spring. 



The internal arrangement of the parts of the bud is 

 the same as in the Chestnut, but the leaves are con- 

 duplicate with the margins turned towards the parent 

 axis as in the Elm.
