and growing point of the epicotyl. Subsequent divisions of the 

 intermediate cell produce the hypocotyledonary portions of the axis 

 as well as the root cap, and the inferior cell of the linear triad gives 

 rise to the suspensor by a series of divisions. As the hypocotyl 

 develops, there is a blocking off of a clearly defined plerome, peri- 

 blem, dermatogen, and root cap.
