are related to the Golgi apparatus of insects, and represent the 

 Golgi material of the plant cell. 



Bowen also recognised two other systems of bodies, the " plas-

tidome ^^ and the ^''pseudochondriome.''' In undifferentiated cells 

 the plastidome consists of distinctly elongated bodies which show 

 a great variety of shape. The pseudochondriome, on the other 

 hand, is characteristically spherical. Multiplication is apparently 

 by simple fission, and at mitosis there is an equal distribution to the
