276 A CYTOLOGICAL INVESTIGATION OF SOME SPECIES 
In the E M C of the sugarcane, reduction-division also doubtless oc- 
curs. Normal synapsis-skeins, spiremes, diakinesis-stages, metaphases 
and interkinesis stages were observed. In as much as each flower con- 
tains but one E M C, which, moreover is usually cut by the knife, the 
chromosomes can but rarely be counted. Diakinesis-stages only can be 
used for counting. The nuclear plate is always lying obliquely in the 
ovule so that there is no chance to observe it from one of the poles. 
Fig. 59 shows a diakinesis-stage of an E M C of the seedling-cane 247 
of Bouricius; in it approximately 40 gemini were present.

That the haploid number was indeed 40, was seen in the case of the 
two anaphases of P MC, pictured in the figures'60 and 61. In fig. 60, 40 
chromosomes are seen in each of the groups moving towards the poles. 
In fig. 61, 38 chromosomes are seen in each of these groups, while 4 
unpaired chromosomes lagged behind in the aegaalhR 3 of which have 
been split alreadly longitudinally. 
In the case of Batjan I succeeded once to count, in an interkinesis- 
nucleus from a megaspore-diad, approximately 40 chromosomes.
