of trees send out young shoots. | 
As I told you before, the usual place for a bud is 
just between the stem and the leafstalk, or the scar left 
by the leafstalk ; but if a stem is cut or wounded, often- 
times it sends out buds in other than the usual places. 
This habit accounts for the growth of young shoots 
from stumps of trees, and from parts of the plant 
which ordinarily do not give birth to buds. 
Some buds never open while fastened to the stem of 
the parent plant; but after a time they fall to the 
ground, strike root, and send up a 
fresh young plant. 
The tiger lily, the plant that grows 
so often in old gardens, bears such 
budsasthese. Wecall them “bulblets” 
when they act in this strange fashion. 
Perhaps even more surprising than 
this is the fact that leaves sometimes

In certain warmer countries grows a plant called the 
Bryophyllum. Wf you look carefully at the thick, fleshy 
leaves of this plant, along its notched edges you will 
see certain little dark spots; and if you cut off one of 
these leaves and pin it on your window curtain, what do 
you suppose will happen? 
Well, right under your eyes will happen one of the 
strangest things I have ever seen. 
From the row of dark spots along the leaf’s edge, 
springs a row of tiny, perfect plants (Fig. 132). 
And when these tiny plants are fairly started, if you
