IV Preface. 



As place for working, I have selected the Botanical Museum 

 of Berlin, where the collection of Cuming is well represented and 

 where I can have access to a large mass of In do -Malayan material. 



By sending specimens to monographers outside of Berlin, I have 

 endeavored to procure reliable type-material and in this respect I 

 have received the kindly assistance of Prof. Radlkofkh (Sapindaceae), 

 Prof. BkccaIv'i (Palmae) and Dr. Bjjand (Symplocaceae), to whom I am 

 greatly indebted. I wish also to express my thanks to the directors 

 of the Konigl. Bot. Museum, Geheimrat Exgi.er and Geheimrat UnuAN, 

 who have kindly placed the facilities of this Institution at my disposal. 



To the several specialists of the Museum Avho have aided me 

 in handling this large material and have given me many useful sug- 

 gestions, i desire also to express my obligations. 



We are only at the beginning of the study of this Flora; there 

 is still an endless amount- to do before we shall possess even a 

 general view of this rich world of flowers, as at present, many 

 districts are still untrodden ground to the botanist. 



Berlin, February, 1904.
