Notes on the above table. — Dioscorca sp. nov. is the species enumerated by 

 Koorders as D. glabra Roxb., but whicli is a distinct undescribed one according 

 to Dr. Prain in lit. and whicli has also been found in the Philippines. Gle- 

 ditschia rolfeiVid.; G.celebica Koord., is a synonym. Pterocarpus echinatus Pers. 

 (P. vidalianus Rolfe) is also known from Salajar Island, south of Celebes. 7 

 Wallaceodendron oelebicum Koord.. a monotypic genus, first found in Celebes and 

 later discovered in the central Philippines. Reinwardtiodendron merrillii Perk., 

 a genus of two species, one Celebes and one Philippine. Koordersiod-endron 

 pinnatum (Blanco) Merr., a monotypic genus known from the Philippines, Celebes, 

 and New Guinea. Cubilia blancoi Blume, a monotypic genus known from Luzon, 

 Celebes, Boeroe, and Cerarn, Cubilia rumphii Blume being a synonym. Anom- 

 jxinax philippinensis Harms., a genus comprising two species, one Celebes and 

 one Philippine. Vaccinium micro phyllum Blume, see page 221. 



Whereas the Celebes connections are very strikingly shown in the above 

 table, the semi-temperate or continental element in the highlands of 

 northern Luzon is nearly as prominent, as is shown by the following one. 

 The latter undoubtedly is far from complete and therefore, when more 

 extensive collections are made and our present material has more 

 thoroughly been worked over with reference to Asiatic types and com- 

 pared with them, the number of species will undoubtedly he; greatly 

 enlarged. 



The noi-thern element in the Philippine flora. — In the following table, 

 as in the preceding, the cross (-)-) indicates that the species is found in 

 Luzon and in the region for which the sign is entered, whereas the 

 dash ( — ) means that the Philippine species is represented by a closely 

 related form in the region indicated, or, in the last column, that the 

 general generic distribution is northern and not Malayan. The majority
