LUSSOJVS WITH PLANTS 



and the section were magnified three 

 or four times, the internal structure 

 would come out plainly, as in Fig. 

 48. The parts are not diflBcult 

 to see with the naked eye. These 

 parts are all present in the bud 

 before it begins to swell, but they 

 are rather small for untrained eyes. 

 We see that the parts are not only 

 smaller than they are in the full- 

 blown flower, but that they are 

 folded or tucked away in an unexpected manner. 



51. An opening pear bud is seen in Fig. 49. 

 It is evident that it is a leaf -bud. It 



is wholly unlike the expanding apple 

 bud (Fig. 44), however. It is long and 

 slender, and curiously marked. Let the 

 pupil watch the pear buds as they open. 

 He will observe that these outer bodies 

 are the bud-scales, and that they soon 

 fall off. These scales have actuallj^ grown, 

 for their former dimensions are indicated 

 by their brown tips. It was these tips 

 alone which covered the bud in winter, 

 and the scales have elongated from be- 

 low. Bud- scales, then, are not neces- 

 sarily lifeless objects.
