No attempt was made to match specimens so as to reduce the total 

 number, but each separate specimen received an individual number. 

 There were no notes regarding the size of the plants, habitat, altitude 

 above the sea, or whether wild or cultivated. Practically all the numbers 

 represent shrubs or trees, with one or two herbaceous and several climb- 

 ing plants. 



Owing to the very unfortunate fact that the herbarium and botanical 

 library at Manila was destroyed by fire in 1897, before the American oc- 

 cupation, it was quite impossible to identify much of the material in 

 Manila, and accordingly the trip mentioned above was planned in order 

 to identify this botanical material and to take advantage of the many fa- 

 cilities afforded at the botanical garden at Buitenzorg. 



At Buitenzorg there were rich collections from Borneo, Celebes, Mo- 

 luccas, Java, Sumatra, the Malay Peninsula, and British India, but there 

 was practically no Philippine material. Little trouble, however, was ex- 

 perienced in identifying those species of wide distribution. In the case 

 of the endemic species, the lack of authentic specimens for comparison 

 was keenly felt, a fact that has had much influence on the description of 

 new species in the present paper. Only five species are described as 

 new in the following article, yet manifestly much of the material that I 

 have placed in the several genera without specific names, is undescribed. 

 It is true that many of the numbers so treated do not represent complete 

 botanical specimens, yet some of them are in good condition and would 

 afford a basis for full and accurate descriptions. In most cases, however, 

 with the lack of authentic Philippine material, it could not be ascertained 

 with certainty whether or not the species had been described, and under 

 the circumstances I have admitted such species without specific name. 



The botanical material named below was collected mostly in the Islands 

 of Luzon and Mindanao during the year 1901, and up to June, 1902. 

 The greatest number of specimens from any one locality was obtained 

 in Camarines Sur, Luzon, in the vicinity of Pasacao, some of the speci- 

 mens being from that town, some from the barrio of Dalupaon, and 

 some from a small river (Tinalmut) near Pasacao. As Dalupaon and 

 Tinalmut are not given on the charts of the region, the specimens have 

 all been credited to Pasacao. Other Luzon material is from the vicinity 

 of Manila, the Province of Tarlac, and the Provinces of Zambales and 

 Benguet. The Mindanao material was chiefly collected in the district of 

 Zamboanga, presumably from the vicinity of the town of Zamboanga, 

 although some were collected at Tetuan and some in the Province of Su- 

 rigao, probably from the vicinity of the town of Surigao, while a few 

 specimens came from Placer. Several specimens are also from Mount 

 Apo in the district of Davao. One or two specimens from Jolo and Pa- 

 ragua, and considerable material from the Islands of Tinago, Bongao, and 

 Dinagat are also included.
