353. Bulblets or Bulbels are small bulbs formed in 

 the axils of the leaves in certain plants, as the tiger 

 lily,* (Fig. 90), or 

 at the apex of the 

 stem, as in the 

 "top" or bulb-bear- 

 ing onion (Fig. 91).

from the bulb chief- tiger uiy. 

 ly in being without scales. The food is deposited in 

 the thickened stem. The conns of our flowering plants, 

 as the crocus, cyclamen, etc., are generally called bulbs 

 in commerce. 



355. The Tuber, of which the common potato is the 

 most familiar example, differs from the corm in being 

 the end of an underground branch of 

 the stem (114), instead 

 of developing in direct 

 contact with the par- 

 ent. It also has more 

 numerous buds (eyes) 

 than the corm. 



356. Propagation 

 from Bulbs, Bulblets, 

 Corms and Tubers is 

 a very simple operation and consists, merely in planting 

 these parts in the place where the plants are desired. 

 Tubers may be cut into pieces containing one or more 

 buds each, if desired. The rules given for planting 

 seeds (344) apply equally well here. All should be
