H. B. or H. Bog. means: herbarium of the botanical 

 gardens of Buitenzorg. 



The tabulae of determination are always arranged in 

 this way that, whenever there could be any doubt in 

 choosing one of two or more alternatives, the genus or 

 species in question is to be found in following both or all 

 the alternatives. 



A bibliography on the subject is given, only containing 

 those works, which are not mentioned in the text (p. 356). 



Under: ..doubtful species" only those species are given, 

 which by no means could be mentioned in the tabulae of 

 determination. For we are in the opinion, that, if we 

 gather in these tabulae as much species as is possible 

 without hurting their security, this gives a greater chance 

 to find the species, or to discover new or synonymous ones. 



For the subdivision of tTie family we used, generally 

 spoken, Engler's System (Nat. Pfl. fam. IV. 3a, 1897). 



Dimensions of inflorescences are always given including 

 the length of the peduncles, if we did not indicate it 

 otherwise. 



In the matter of varieties we started from the principle, 

 that they stand in reason to the species, as this does to 

 the genus. Thus we eventually subdivided the species 

 into var. a (often, typicus, -a, -um), var. ,3, etc. 



Also plants imported into or cultivated in the regions 

 dealt with, are mentioned.
