(aster), closely-packed loops appear, so that when seen from 
the pole it does not present the form of a star, with an empty 
centre, but resembles a plate made up of threads closely col- 
lected together in one plane. We have already explained what 
is meant by “ Aequatorialplatte ” and “‘ Metakinesis ” (see espe- 
cially the remarks on pp. 177,178). Finally, it should be men- 
tioned that Strasburger has recently used the name “ prophase” 
for all the karyokinetic phenomena, up to the longitudinal 
splitting of the threads ; “‘ metaphase” for the stage of division 
itself up to the complete separation of the daughter-threads; 
and “anaphase” for the remainder of the phenomena, up to 
the establishment of the resting daughter-nuclei. For the 
star figures of the cell-body, the so-called “ Polstrahlungen,” 
(polar rays), we may with Flemming use the term “ Cytaster”’ 
(helioma, aureola) : for that of the nucleus, i.e. the spindle 
figure (Kernspindel, in Flemming’s sense), the name “ Kary- 
aster.” 
Carnoy used the name “ Cytodiérése ” (after Henneguy (92)), 
for cell division. 
Strasburger (192) now arranges the course of phenomena 
during mitosis for the higher plants—essentially in agreement 
with Flemming—in the following way : 
I. Prophase. 
. Network of the resting nucleus. 
. Dense skein or coil. 
. Loose skein or coil. 
. Displacement towards the nuclear plate. 
. Nuclear plate (equatorial plate—mother-star). 
II. Metaphase. 
6. Separation and displacement of the secondary segments 
(metakinesis).

III. Anaphase. 
7. Star (daughter-star, dyaster). 
8. Loose (daughter-) coil. 
9. Denser (daughter-) coil. 
10. Network of resting daughter-nucleus.
