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 l 

 and note 



(a) The short, thick, conical 

 stem. 



(6) 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.
