508 THE CYTOLOGY OF THE SUGARCANE : 
seen. In each of the two groups moving towards the poles, 33 chro- 
mosomes are present, while 14 are seen on the equator.

Doubtless the diploid number of EK 28 is 80. 
In the preparations of one inflorescence, nearly all divisions show 
a considerable larger number of univalent chromosomes than occur 
in the preparations of the other inflorescences. Fig. 12 pictures a 
diakinesis-nucleus from a flower of this inflorescence. The univalent 
chromosomes are, almost without exception, arranged in sets of 
two; the chromosomes of one set often are arranged approximately 
parallel to one another, but are not united to a pair. Gemini are 
also present, but are less conspicuous. About 42 univalent and 
19 bivalent chromosomes could be counted in this nucleus, which 
again points towards 80 as the diploid number. Nuclei like the 
one pictured in fig. 12 were very common in these preparations.
