 found, but to judge 

 from these the cysto-

 the usual way found 

 in the Rhodomelacese . 

 One of the pericentral cells is divided by a longitudinal wall into 

 two cells: one of these being the auxiliary mother cell, the other 

 one producing the carpogonial branch. The trichogyne is rather
