Fig. 7. Reconstructed daughter nuclei with polar depression, nucleoles beginning 
to appear. The polar structures contain abundant starch, the upper one 
is as well developed as the lower but most of it lies in the next section. 
Fig. 8. Spore-mother-cell of Equisetum hyemale in synapsis. A dense aggre¬ 
gation in the cytoplasm lying against the nuclear membrane opposite the 
synaptic mass, the cytoplasmic fibers are centered upon this granulär 
aggregation. 
F'ig. 9. Spore-mother-cell of Marsilia quadrifolia in synapsis. Here the gran¬ 
ulär aggregation (largely starch) in the cytoplasm lies against the nuclear 
membrane next to the synaptic mass.
