My dear Dr, Standley; 
I have received notice that the spec¬ 
imens mentioned in your recent letters have been for¬ 
warded to me. As soon as they arrive I will give them 
prompt attention and send you determinations of the 
Central American and Brasilian species.

Central American orchids are now taking 
up ail of my time including Sundays and holidays. I am 
aix’&id that neither of us realized what a tremendous 
task this Central American orchid venture would prove 
to be. ihe critical work necessary to pave the way 
for reliable keys is still far from done. The larger 
and more difficult genera have been keyed, however, 
and the mechanical work of writing descriptions simply 
involves the time element necessay to finish them. It 
would be well now to tell the latest date at which the 
wonc ought to 06 completed. In doing this give me as 
much oimo as possible as I have not yet completed the 
study of undetermined specimens lying in my herbarium. 
I want all the time I can be allowed. Write about this 
in detail.
