 spaces occasionally resin is found. 



The remainder of this parenchy- 

 matous portion of the rhyzome is 

 composed of large, oval, thin-walled 

 cells, with numerous small inter-cel- 

 lular spaces. The majority of the cells 

 contain small, round starch - grains 

 (see Fig. 1). Many of these cells are 

 modified glands or sacks, and contain 

 the bright yellow coloring-matter.
