FIG. 78. Fritillaria persica ( x 800 : after Strasburger). Division of a mother-cell of the 

 pollen : a contraction of the fibrillar network ; c kinoplasmic spindle with equatorial 

 nuclear disc seen in profile ; b and d nuclear disc seen from the pole, in b the fibrils are 

 splitting longitudinally ; e division of the nuclear disc into two ; / separation of the two 

 halves of the nuclear disc ; g two nuclei still connected by spindle- threads, in which the 

 cell-plate is forming ; h-m division of the daughter-cells ; h and i, breaking up of the net- 

 work and formation of kinoplasmic spindle; fc spindle, in profile in the right, from the pole 

 in the left; I separation of the segments, in profile in the right, from pole in the left; 

 TO nuclei with connecting threads and cell-plates.
