end ; the brown part becomes shorter, and after one or 

 two days disappears altogether ; they are fringed with 

 hairs. As the stipules expand the shoot turns down, 

 so that the leaves hang towards the ground. The stip- 

 ules are often a rich purple. 



the hazel nut (Oorylus AveUana) 



The bud of the Hazel Nut (Corylus Avellcma) 

 (fig. 212) is protected by stipules which gradually in- 

 crease in size. The first four pairs 

 are without leaves. The fifth have 

 a well-formed leaf. The second pair 

 and following stipules are fringed 

 with fine hairs round the edge. The 

 stem and petioles have two kinds 

 of hairs: 1, fine, silky, white and 

 more or less adpressed ; and, 2, red- 

 dish, upright, glandular hairs. The 

 young shoot bends over downwards 

 for protection from cold. The leaves 

 are conduplicate. The stipules are 

 often beautifully pink.

they are a rich brown, and make a beautiful contrast
