NORMAL AND BRACHYTIC MAIZE STALKS 
Showing the internodes just above the svr-ace of the ground. Note that while in the 
brachytic stalk six internodes have been “compressed” into the space normally oc- 
cupied by one and a half, the thickness of the stalk has not been diminished at all in 
the process. With short internodes, more nodes produce roots below the surface of 
the ground. Photograph natural size. (Fig. 12.)
