Note on some Nuclei found in Grasses. 
NOTE ON SOME NUCLEI FOUND IN GRASSES. 
By Jessie S. Bayliss, D.Sc. (Birm.), 
(Lecturer and Demonstrator in Botany iti the University 
of Birmingham). 
N the course of an investigation of fungi causing “ Fairy Rings” 
in fields, I have examined very many sections of the rhizomes 
of healthy grasses for comparison with infected ones, and have been 
impressed by the extremely elongated form of the nuclei which 
occur in the steles but never in the cortex or pith. Most of them 
were vermiform or curved rather than straight, and a few were 
apparently bifurcate (a) at one end ; they were 20 or 25 times 
longer than their diameter ( b, c). 
In Brotnns mollis very many of them had a length of 22g 
and others were as long as 47/x and even 52/x, while the narrow 
diameter only 2g. 
They are evidently of general occurrence in grasses, since 
they were found in the rhizomes and flowering haulms of 
Triticum caninum, T. repens, 
Since I have found no 
reference to such elongated 
nuclei in any botanical 
literature I thought it might 
be well to draw attention 
to them by means of this 
note. 
They were only to be 
seen in the actively growing 
tissue at the bases of the 
internodes.
