Dear Mr. Schweinfurth: 
There is room for considerable flexi¬ 
bility in treatment in the Flora of Peru, as you will see when 
the next part appears, that is, the one following the grasses, 
which is now being set up. Macbride originally did not wish 
to include descriptions of new species, but recent develop¬ 
ments have shown "that plan impractical. The next part to 
be published—it will appear in a few weeks—consists chiefly 
of Latin descriptions of new Piperaceae, so there is no reason 
why new orchids should not be included. Incidentally, it 
is not necessary to have descriptions as brief as those in the 
part already published. In the part treating the Rubiaceae, 
to go to the printer within a few days, the species and genus 
descriptions are rather ample, and they may be just as long 
as seems desirable to you. 
As a rule, in citing specimens, the departments have 
been cited alphabetically, but there may be many deviations 
from this practice. 
If matters remain as at present as regards WPA assist¬ 
ance, the Orchidaceae can be published just as soon as the 
manuscript is ready. I don't know what has happened with 
the list of Costa Rican plants. The Director would like to 
have it published here, as things are now^but I do not wish, 
to take it away from the people at San Jose, if they are 
going to make some headway with it. Especially would I dis¬ 
like rewriting it in English, which would be almost as much 
work as the preparation of the original Spanish manuscript. 
Sincerely yours, 
I have here^on my desk "Plantas utiles de Colombia," by- 
Enrique P. Arbelaez of the Ministerio de Agriculture., Bogota, 
Colombia. Have you seen it? I ask because it contains some 
rather nice original sketches of Colombian orchids.
