that the cell at its base reind.ins broad a,nd flat, retaining 

 the appearance of a basal cell of a procari) (fig. 75) . In 

 sucii cases the first peripheral cell, v/hich is really a 

 terminal cell, functions as an apical cell of a vegetative 

 branch, 



Prom the second or third peripheral cell the carpo- 

 genie branch is formed laterally. The peripheral cell from 

 which the carpogenic branch is produced is the "supporting 

 cell" of Miss SfflTH, and is equivalent to the "avDciliary 

 cell" of HASSEI'iCAI'.CP ('02). In this account I shall adopt 

 the term auj>:iliary cell, H^Froii i"t a small ununlcleate 

 cell is produced laterally, which is the basal cell of the 

 carpogenic branch. This cuts off a terminal cell, v/hich in 

 turn divides (fig. 74) . The upper of the tiiree cells so 

 formed divides again, thus fonaing a carpogenic branch of 

 foui" cells (fig. 76) . The carpogenic branch is bent at 

 right angles in such a way that the terminal cell, from 

 \.hich the carpogonium and trichogyne are formed, is usu- 

 ally in contact with the auxiliary cell. Each cell of the 

 carpogenic branch is at first uninucleate. From the free 

 border of th'^ terminal cell the trichogi/Tie is produced as 

 a club-shaped projection (fig. 76 a) . wlaether a diijision 

 of the nucleus of the carpogoniiim accompanies the formation
