12a. Can these remarks be made for most 

 bushes? That is, do they make single ter- 

 minal buds the first year or two from the 

 seed, and afterwards begin a new habit of 

 bud-bearing? If the pupil does not have 

 access to young plants, he may examine the 

 sprouts or ' ' suckers ' ' which spring from tue 

 roots of common bushes, as lilacs, roses, 

 spireas, osiers, willows, barberries, privets, 

 and the like. He may also study the horse- 

 chestnut. 



13. Some bushes seldom make 

 single terminal buds. The red 

 elder (Fig. 7) is one. In this 

 case, therefore, it would seem 

 if the forking system of 



as 



growth must commence at the 



very beginning of the plant's 



history. The lilac is a similar 



case. Fig. 8 shows the shoots 



just pushing out from the ends 



of "suckers" which sprtag from 



the ground. The specimen at 



the right shows the twin shoots, 



but one is stronger than the 



other. That is, in the struggle 



for existence one has the start. 



The sample at the left shows 



only one shoot, but the other 



bud, which has lost its opportunity, is seen
