353- Bulblets or Bulbels are small bulbs formed in 

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

 at the apex of the 

 stem, as in the

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

 in commerce.

 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
