FLORA OF THE PHTLTPPINE ISLANDS. 307 



allow of a large amount of specific modification under altered 

 circumstances ; also that with the waning of the volcanic forces 

 a period of comparative stability set in, allowing a limited amount 

 of specialization in the different islands themselves. I think it 

 will therefore be conceded that the foregoing outlines show 

 that the Philippines are truly insular in the essential features of 

 their natural history ; not so much through being au early sepa- 

 ration of the Asiatic continent which has since had a dip under 

 the sea, as through their being largely of volcanic — and, geo- 

 logically, of somewhat recent — origin, as in the case of other 

 islands of admitted oceanic origin. 



The following alterations, with descriptions of a few novelties, 

 have been made during a study of the Philippine collections. A 

 number of additions to Villar's ' Novissima Appendix ' had been 

 written out, also species included by error, or that will have to 

 be reduced as synonyms, had been indicated ; together with a few 

 erroneouslv reduced synonyms, or that will have to be trans- 

 ferred to other species ; but as in the absence of a complete set 

 of authentic specimens the Appendix would still be incomplete, 

 it has been thought better to suppress them, at least for the 

 present, though they are taken account of in estimating the 

 numbers for the foregoing Census.
