In this paper 8 large number of genera winch were previously unknown 

 from the Philippines are for the first time reported, their representa- 

 tives in some eases being species heretofore nndescribed and. in others. 

 well-known plants which for the first time haw been encountered in 

 the Archipelago. 



KollV- makes it clear that the Philippine llora has distincl connections 

 with that of the neighboring lands, hut. at the time he wrote, compara- 

 tively little was known regarding this llora or that of the regions im- 

 mediately to the north and south. In the past twenty years much work 

 has been done by various authors; 1905 has seen the completion of 

 Forbes and Hemsley's work on the Mora of China, 3 and in L898 Reorders 

 published his compilation of that of Celebes. 4 



liolfe, in 1884, knew but three species common to the Philippines and 

 Celebes ami confined to these two regions ami only about sixteen which 

 he considered to represent northern or continental types; therefore it 

 has been thought advisable here to enumerate some of the more striking 

 representatives both of the southern connection with Celebes and of the 

 northern one with Formosa. Japan, and the Asiatic Continent, especially 

 as I'steri/' publishing as recently as the year L905, has added nothing 

 to the twenty-year-old list of Rolfe. 



The list of species confined to Celebes and the Philippines and com- 

 mon to both has been extended from the three mentioned in L884 to 

 about sixtv given below, while many others extending from the Philip- 

 pines through Celebes to neighboring islands, have been enumerated. 

 The list, so far as Celebes is concerned, is based largely on Koorders' 

 work, cited above. Koorders 6 remarks that the relationship between 

 the Philippine and Celebes llora is very prominent, but does not discuss 

 the connections in detail. 



] n the following table the cross ( + ) indicates that the species is 

 found in Luzon and Celebes and. unless noted to the contrary in the 

 last column, that it is known only from the two regions. The dash ( — ) 

 indicates that the Philippine species is represented in Celebes by a 

 closely related one or a variety. The question mark indicates a Philip- 

 pine species doubtfully credited to Celebes by Koorders. Where the 

 range of the species is known to extend beyond Celebes, its distribution is 

 given in the last column. Specimens of most of the species enumerated 

 are in the herbarium of this Bureau.
