Dear Sir, 
I am at present conducting experi- 
ments in this Department on root parasit¬ 
ism, especially in relation to Striga 
spe c ie s. 
I should he glad to know if any 
parasitic Striga is to he found in your 
area, and, if so> if you could put me 
in touch with someone who might he arj~e 
to send me a supply of seed of this 
plant. 
It is not necessary that the '■ 
particular species should he identiiied; 
I will he able to do this if a hercarium 
specimen of the type of plant from which 
the seed is obtained is sent to me along 
with the sample. If possible, the seen 
should he sent in sealed containers. 
I hope that this request will not 
put you to any great inconvenience. As 
far as Government regulations permit, I 
sh'all he glad to refund any postage or 
other expenses incurred by you on my 
behalf. 
Y 0 urs faithfully, 
A? U 
K.B. Vallance.
