26 FAMILIAR LESSONS IN BOTANY. 



upon the extremity of the branch is called the terminal 

 bud. 



57. There are three kinds of buds: floAver buds, leaf 

 buds, and mixed buds. The flower bud is generally round- 

 ish, and contains tlie rudiments of one or more flowers. 

 The leaf bud is longer than the flower bud, and contains 

 not only the leaf, but the rudiments of the future branch. 

 Consequently, the arrangement of the branches on the tree 

 must be identical with the situation of the leaves. Mixed 

 buds contain both leaves and floAvers. The lilac bud, if 

 cut longitudinally, and placed under a magnifying glass, 

 will exhibit a beautiful example of this kind of bud; its 

 leaves and flowers will be seen compactly inclosed to- 

 gether. 



58. I have now told you where to find the buds, how 

 they Avere protected during the winter, and that there were 

 three kinds of buds. But there are a great many trees 

 that have no scale buds at all. The young buds make 

 their appearance and push out from the node at all seasons 

 of the year, seemingly in the most reckless and disorderly 

 manner. These trees, however, are not so improvident 

 and foolish as you might suppose. The fact is, they are 

 all natives of Avarm climates, where such precautions as 

 extra coverings, felt-lined leaves, varnished coats, and dry 

 scales are totally unnecessary. The men and w^omen of 

 tropical countries do not dress in woolens and furs, neither 

 do the plants put on extra covering. Nature does no un- 

 necessary work; we always find everything properly ad- 

 justed to the circumstances that surround it. Some trees, 

 when taken from the tropics to more northern climates, 

 form scales for their buds, and are thus enabled to con- 

 tend successfully with the rigors of climate, while others 



5 7. How many kinds of buds are there? What of flower buds ? Leaf buds? 

 Mixed biida ? Example of mixed buds ? 



58. W^hat have you now been told ? Are there trees that have no scales? Why 

 do not the trees of tropical climates form scale buds? Do they ever learn to do 

 It ? Mention some.
