EXPLANATION OF PLATE II. 
Resting fusion nucleus. 
Early prophase of division. 
Later propliase. 
Later propliase showing the splitting of the 
chromosomes. The nucleolus has lost 
its rounded contour. 
Equatorial plate stage showing central 
bodies, chromosomes, spindle and polar 
radiations. 
Equatorial plate stage showing central 
bodies, chromosomes, spindle and polar 
radiations. 
Anaphase showing chromosomes grouped 
about the poles. Polar radiations are 
present. 
Conjugate division showing the dumbbell 
shaped chromosome masses and the nu¬ 
cleoli occupying positions at the sides. 
Conjugate division. ETuclear division is 
complete and cell division is taking place 
by constriction. 
The second division in the promycelium. 
Centrosomes and polar radiations are 
present. 
An apical mycelial cell showing the binu- 
cleated condition. 
Haustorium in cell of host plant One 
nucleus only has entered the haustorium. 
Cell of host plant showing binucleated 
haustorium, nucleus of host plant and 
chlorophyll bodies.
