Dear Henderson, 
I have iust been informed by Dr. van Steenis 
that Mr. Domke, Herbarium, Berlin-Dahlem, Kon.Luisestr.6-8 
is finishing a monographic work on Gonystylus for Bull. Jard 
Bot. Bog.. Dr van Steenis suggests that we would mutually 
benefit by sending our material of this genus to Berlin 
and I am despatching ours now. He suggests that you might 
like to send your material also. Perhaps you have already 
done so. 
I had an interesting trip the other day to 
the top of that limestone rock near Kanching and made some 
interesting collections. Pistacia malayana and, curiously, 
Podocarpus polystachys are abundant on the top of the rock. 
I hope you have had, or are having, a good 
time in Java. 
To,
