and fleshy roots are also of common occurrence, e. g., the wild 

 carrot, wood betony, dandelion, etc. In many cases the short 

 stem itself is the storage organ and consequently it becomes en- 

 larged and fleshy, as in the Jack-in-the-pulpit, garden crocus, 

 spring beauty, etc. (Fig. 73, A). These short erect stems are 

 termed corms and are suggestive of the tuber. In other plants 

 the bases of leaves attached to the short stems function for the 

 storage of food, as in the bulb type of stems of lilies, onions, etc. 

 (Fig. 73, 5).
