by dear ,.r. Standley; 
An orchid flora of Costa idea 
written along, th lint;?; you pr°P°s6 would be a purely 
mechanical job for me now as I have worked on a 1 of 
the species and have arrived at definite views with 
regard to synonymy. The trouble i t that I cannot 
promise to work at the manuscript until after the 
close of the academic season, but I suppose even at 
that I should be able to meet our desires, 
e are very busy with the key to 
the : orthAiaerican species of .pidendrum, I t .ink this 
will be a welcome product. It certainly has received 
concentrated a tention through a number of years and 
represents the fruit of prolonged research. 
"Very sincerely yours»
