M. G. Sykes, Nuclear Division in Funkia. 
Figs. 49 & 50. show the origin of the mnltipolar spindle fibres and tlie 
attachment of the cbromosomes by the middle. (X 1150,'. 
Fig. 51. shows the gathering together of the chromosomes to form an 
equatorial plate. Fach loop shows clearly its double natnre. 
Fig. 52. Metaphase. Equatorial plate stage, showing longitudinal fission 
of loops. (X 1150). 
Fig. 53. Anaphase, just after division, the short chromosomes having 
already separated. (X 1150). 
Fig. 54a, b, c. shows various stages of division of the long chromosomes; 
d, c show Separation of short chromosomes. 
Fig. 55. Telophase of heterotype division; in most of the chromosomes 
a second longitudinal split is now visible and this is more pronounced in 
(X 1150). 
Fig. 56 where it is seen in almost every chromsome. (X 1150). 
Fig. 57. Reconstruction of the daughter nuclei ; one nucleolus is present 
and the double nature of the disappearing chromosomes is still evident. (Rei- 
chert Via)- (X 1350). 
Figs. 58 & 59. Later stages of same, showing double nature of both knots 
and reticulum. 4X1150 . 
Fig. 60. Prophase of homotype; three nucleoli are present. (X 1150). 
Fig. 61. Metaphase of homotype division. The chromosomes are attachet 
by their ends and have divided longitudinallv. (X 1350). 
Fig. 62. Telophase of homotype and formations of cell plate. Note the 
long thin chromosomes. (X 1350). 
Figs. 63 & 64. Nuclei of young pollen grains with unpaired reticula and 
2 — 3. nucleoli. (X 1150).
