Ill this paper a large luunber of genera Avhicli were previoiisl}^ unknown 
from the Philippines are for the first time reported, their representa- 
tives in some cases being species heretofore imdescrihed and, in others, 
well-knoAvn plants Avhich for the first time have been encountered in 
the Archipelago. 
Polfe - makes it clear that the Philippine flora has distinct connections 
Avith that of the neighboring lands, but, at the time he Avrote, compara- 
tively little Avas knoAvn regarding this flora or that of the regions im- 
mediately to the north and south. In the past tAventy years much Avork 
lias been done by various authors; 1905 has seen the completion of 
Forbes and Hemsley’s Avork on the flora of China,® and in 1898 Ivoorders 
published his compilation of that of Celebes. 
Kolfe, in 1884, kneAv but three species common to the Phili])|)ines and 
Celebes and confined to these tAvo regions and only about sixteen Avhich 
he considered to represent northern or continental types; therefore it 
has lieen thought advisable here to enumerate some of the more striking 
representatives both of the southern connection AAdth Celelies and of the 
northern one Avith Formosa, Japan, and the Asiatic Continent, esjiecially 
as Usteri,® ])ublishing as recently as the year 1905, has added nothing 
to the twenty -year-old list of Polfe. 
The list of species confined to Celebes and the Philippines and com- 
mon to both has lieen extended from the three mentioned in 1884 to 
about sixty given below, Avhile many others extending from the Philip- 
}iines through Clelebes to neighboring islands, have been enumerated. 
The list, so far as Celebes is concerned, is based largely on Ivoortlers’ 
Acork, cited above. Koorders ® remarks that the relationship hetAveen 
the Philippine and Celelies flora is very prominent, hut does not discuss 
the connections in detail. 
In the folloAving table the cross (-]-) indicates tliat the species is 
found in Luzon and Celelies and, unless noted to the contrary in the 
last column, that it is knoAvn only from the tAvo regions. The dash ( — ) 
indicates that the Philijipine species is rejiresented in Celebes by a 
closely related one or a variety. The rpiestion mark indicates a Philip- 
])ine species doubtfully credited to Celelies by Koorders. Where the 
range of the species is knmvn to extend beyond Celebes, its distriliution is 
given in the last column. S])eciniens of most of the species enunierateil 
are in the herharium of this Bureau.
