Dear Dr. Henderson, 
Returning from my trip over Java and Sumatra, 1 am able at last to 
answer your letter,announcing the posting of the plants,collected in 
Johore. May I thank you for your kindness to provide them with names ! 
Have you ever "been again to that peat forest? They tola me,that 
Miss B. Polak from Amsterdam,who is a specialist in tropical peat "bogs 
will come to the Indies. She studied already the bogs of Sumatra and 
of Borneo,but I suppose she doesn't know there are any in the Siraits. 
I hope,there will be left something of that peat forest! 
Under separate cover are posted to you and to Mr. Hurtado some papers 
on Lauraceae; in your copy you will find some snapshots I have made 
on the trip to the mud coast. 
I have altered my plans so far,as I am intended to remain a couple 
of years in the Indies,to complete my studie s here. I hope to be able 
to visit the Straits once more! 
I hope,you will accept my thanks once again for your kind help 
during my visit to Singapore. 
With kind regards,also to Mrs. Henderson 
Yours sincerely 
(dr, A.J.Kostermans )
