distinct physiological strains in the 
S' lutea species, we are anxious for 
seed from, many localities for purposes 
of comparison. Obviously, we are 
dependent on the generosity of colleague 
working in these localities for our 
source of seed. If, therefore, you 
could continue to send us samples of 
seed from time to time, as far as is 
convenient to you, we should be most 
grateful. 
I shall be delighted to send 
you copies of any papers I publish on 
this work at any time. 
With many thanks for your 
interest in this work, 
Yours sincerely, 
ye
