In this catalogue the first column contains the permanent herbarium 

 number, in combination with the Greek letter Beta, which is the initial 

 letter of the old Javanese name of Buitenzorg, i. e., Bogor. The second 

 column contains the Latin name of the plant ; the third its family, gen- 

 erally abbreviated ; the fourth, the field number of the plant ; the fifth 

 its local name ; while the sixth is reserved to note whether or not ma- 

 terial other than dry herbarium specimens was preserved; A.=alcoholic 

 material; B.=bark; W.= wood, etc. 



At the end of one or two, or at most three years after a type area has 

 been selected and the trees numbered, it is revisited and careful notes 

 are made of the changes that have taken place in the time elapsed. A 

 second set of botanical specimens is also prepared at this time. The type 

 areas are visited as often and as many times as may be necessary to se- 

 cure the information available or desired. 



This careful method of working out the forest flora under tropical con- 

 ditions not only furnishes the most accurate information concerning the 

 geographical distribution and scarcity or abundance of the many individ- 

 ual species but makes possible a most careful check on the accuracy and 

 value of the many native names, and on the economic uses of the different 

 species. Often it is found that "floating" names exist — that is, the same 

 name is affixed to several different species, or to groups of related species — 

 and on the other hand, names applied to certain species, especially to 

 those of economic importance, will be found to be quite invariably ap- 

 plied to the same species. By preparing such a series of careful notes on 

 the many species, and by checking over the local names each time a type 

 area is visited, one can soon readily determine which of the native names 

 are trustworthy and which are doubtful and should be discarded. 



In the Philippine Archipelago, extending as it does over about fifteen 

 degrees of latitude, there are probably 1,500 distinct species that would be 

 classed in the forest flora; and of these 1,500 species some 75 or 80 per 

 cent attain a diameter of ten or more centimeters. With this exceedingly 

 large number of individual species, in order to obtain any definite knowl- 

 edge of the component species of the Philippines forest flora, the extent of 

 the forest areas, prevalence of valuable economic species, etc., it is quite
