Bengal (1889—1909), various other papers by different authors 
on the flora’s of the Indo-Malayan region and the Philippines, 
besides recent monographs of families, subfamilies and genera. 
In all cases of regional distribution, except Sumatra and the 
Philippines, Roxrr’s lists have been increased, in most cases 
enormously so, while the list of Sumatra-Philippine plants has 
been decreased. The discrepancies between the following lists 
and those previously published as indicating the same distri- 
butions, are due largely to the fact that most of the excluded 
Species have been found to extend over a much greater area 
than was at first supposed, and hence no longer serve to 
illustrate special alliances. There is no doubt but that, as bo- 
tanical exploration progresses, many of the species iucluded in 
the following tables will have to be discarded, as they will 
be found to have a greater range than is at present known. 
Doubtless too the matter of limitation of species and identifi- 
cations will play its part in displacing some from the list, as 
comparative and monographic studies will probably show that 
in some cases specimens from different regions that have previ- 
ously been referred to a single species, will be found to represent 
different, although in most cases probably closely allied ones. 
The flora of the Phillippines is as a whole preponderatingly 
Malayan, and has in most part evidently been derived from 
that region. It has, on the other hand, received some elements 
from the north that have not reached the Malayan region, 
and also a considerable number of Australian and Polynesian 
types that do not extend to Western Malaya, and only a few 
of which have as yet been found in Eastern Malaya. Represen- 
tatives of about five families have been found in Malaya that are 
at present not known to occur in the Philippines: Butomaceae, 
Linaceae, Valerianaceae, Phytolaccaceae, and Podostemonaceae, 
While on the other hand three families, Buxaceae, Elatinaceae, 
and Coriariaceae are found in the Philippines but have not been 
reported from Malaya. Turning to the matter of genera it is 
found that of the phanerogams alone about 1144 genera are 
‘ommon to Malaya and the Philippines, while the Malay-region
