Sir Alfred Russell[sic] Wallace

Dear Sir,

My paper on the flora of N. E. Celebes asked for in your postcard of Jue[sic] 11th, immediately after the receipt of your postcard has been despatched to your address. But the information asked in your ^interesting letter of May 9th, at this moment I am sorry I can impossible give to you, because I am extremely busy with official work. I hope you will excuse me and take the information as far as regarding to Celebes from my paper, which I now have sent to you as as far to the flora of Java from my publications, which are ^represented in the library of the Royal Botanic Gardens in Kew and further I hope, you will find much ^some of the information you want in my book on the phanerograms of the highest mountains of Java. The last book has been written by me in Europe and and[sic] finished on December 15th last year, but I did not yet succeed in putting aside all the difficulties against getting it printed ^now with all the botanical photographs and drawings, which I made ready for it. Therefor[sic] I hope you will excuse me at thi this moment and will ^kindly wait till my book on Java flowering plants of the mountains of Java at last will be published. — Allow to me at last to put your attention on the genus Wallaceondendron in my Celebes-paper. — The old rough estimate of 1500 species of trees in Java ^{mentioned in your letter} has not increased by my researches, buy ^{has been} reduced t by me to about 1200 species, especially by two causes: 1^d many species of Blume and Miquel prooved[sic] not to a be specially different and were united in Koorders & Valeton Bydragen Boomsoorten Java; 2^d some species mentioned in literature prooved[sic] by our researches not to be wildgrowing in Java.

Believe me yours faithfully | S. H. Koorders [signature]
