work in Amboina, the list of doubtful species has been greatly 

 reduced. 



In the present consideration about 930 of the Rumphian species 

 have been definitely referred to binomials, and of these about 

 470 are definitely represented by botanical specimens collected 

 by Doctor Robinson. It should be borne in mind, however, that 

 many of the species that are not represented by specimens 

 collected by Doctor Robinson were originally described by 

 Rumphius from material that did not originate in Amboina, 

 much of it coming from distant lands (see p. 14) . 



There are about 45 species, proposed by various authors, that 

 are known to-day only from the data originally given by 

 Rumphius; that is, those species that have not been, to my 

 knowledge, definitely and correctly connected with actual bota- 

 nical specimens from which in turn their true characters and 

 relationships can be determined. Among these species of 

 doubtful status are the following:

Doubtless some of these species are represented in herbaria 

 rich in Malayan material, but so far as published records go, 

 such specimens have never been definitely connected with the
