In other cases the wall of the mother-cell presents ingrowths at points correspond- ing to the lines along which the cellulose walls are formed, and this conveys the erroneous impression that the wall of the mother-cell grows inwards constricting the protoplasm and ultimately dividing it into four parts. A good example of this case is afforded by the development of the pollen-grains of Dicotyledons. Fig. 1 r, taken from Tropseolum minus, will serve to illustrate it. In a four nuclei are present, which have been formed in the manner described above with reference to Equisetum: they are connected by.
