an adventitious bud, but these are very rare though the ten- 

 drils of the vine are produced from such buds. 



Some buds may be latent or dormant, i.e., remain undeveloped 

 for a long time. These may become active when the ordinary 

 buds have been destroyed by frost or accident. Trees in spring 

 may have their leaves destroyed by frost, but after a few weeks 

 a new set of leaves are developed, which are formed from latent 



buds. Latent buds may thus 

 save the life of the tree. Even 

 when in the dormant state these 

 buds increase in size and give 

 T rise to balls such as are often 



seen, under the bark, in the 

 Beech, Chestnut, and Lime. 

 Latent buds also give rise to the

knots which are found in timber. If the main shoot of the Oak 

 and Beech be cut down, a dense outgrowth of branches, formed 

 from the base of the shoot, occurs ; this is called tillering. The 

 new outgrowth is formed from the dormant and adventitious 

 buds. It is a very common practice for farmers in the spring 

 to roll the wheat which is sown in winter ; this is to make it
