two polar nuclei, and three antipodal cells. The antipodals 

 divide further, as is the case with other Gramineae. . The nuclear 

 division of these antipodals is either direct or indirect, and the 

 former seems to be more usual than the latter.* I have observed

the mitosis only in a few cases; and the chromosomes were found 

 making a compact mass, so that the individual chromosomes 

 were not well distinguished. The nuclear division is not always 

 accompanied with the cell- wall formation. Thus a large cell is 

 formed, which may contain as many nuclei as 14, so far as I 

 have counted (Text- fig. B. e). The number of the cells varies 

 from 6 to 20, or sometimes much more. 



* Koernicke (6) found no mitotic figure in the antipodals of Trittcum. So he is 

 inclined to believe Ihatonly the amitosis takes place here. _._...:_';
