BUDS

examined for himself are not large enough to show in the 

 most obvious way the relation of the parts and their real 

 nature. 



Fortunately, it is easy to obtain a gigantic terminal bud 

 which illustrates perfectly the structure and arrangement 

 of the parts of buds in 

 general. 



Examine and sketch a rather 

 small, firm cabbage, preferably 

 a red one, which has been split 

 lengthwise through the center 1 

 and note 



(a) The short, thick, conical 

 stem. 



(&) The crowded leaves 

 which arise from the stem, the 

 lower and outer ones largest 

 and most mature, the upper 

 and innermost ones the small- 

 est of the series. 



(c) The axillary buds, found 

 in the angles made by some 

 leaves with the stem. 



Compare the section of the cabbage -with Fig. 86. 



Most of the buds so far considered were leaf-buds, that 

 is, the parts inside of the scales would develop into leaves, 

 and their central axes into stems ; but some were mixed 

 buds, that is, they contained both leaves and flowers in an 

 undeveloped condition. 



Flower-buds contain the rudiments of flowers only. 



Sometimes, as in the black walnut and the butternut, 

 the leaf-buds and flower-buds are readily distinguishable 



1 Half of a cabbage will be enough for the entire division.
