Of the species here reported from the Philippines for the first time, 

 many represent interesting, and, in some cases, peculiar cases of geograph- 

 ical distribution. The following species were previously known only 

 from Celebes: Ficus minahassce Miq., Wallaceodendron celebica Koor- 

 ders, Gleditschia celebica Koorders, Acetephila gigantifolia Koorders, 

 Cratoxylon celehicum Blume, Strychnos celebica Koorders, Couthovia 

 celebica Koorders, and Glerodendron minahassce Teysm. and Binn. 



The following species were previously known only from the Moluccas: 

 Casearia molmca?m Blunie, Lepiniopsis ternatensis Valeton, Cleroden- 

 dron lanuginosum Blume, Ixora amboinica Decne, Albizzia littorali^, 

 T. and B. 



From Java : Luecosyke alba Zoll. and Mor., Parinarium scabrum Aubl., 

 Picrasma javanica Blume, Saurauia reinwardtiana Blume, Albizzia to- 

 mentella Miq., and Ilydnocarpus heterophylla Blume, the latter also 

 known from Sumatra. 



From Borneo : Shorea scrobiculata Burck. Probably many other Phil- 

 ippine plants will be found in Borneo later when the flora is worked up. 

 At present much of the Borneo material at Buitenzorg is undetermined. 



From Burma, the Malayan Peninsula, and Sumatra: Pinus khasya 

 Royle, Walsura robusta Roxb., and Erythroxylon burmanicum Griff. 



Among the cases of geographical distribution of special interest must 

 be noted the relatively large number of recently described Celebes species, 

 which are here noted for the second time from the Southern Philippines ; 

 the discovery of Lepiniopsis ternatensis Valeton, in Mindanao ; 4 distinct 

 species of the genus Pinus from the mountains of Northern Luzon; and 

 the discovery of Hydnocarpus heterophylla Blume, Payena, leerii B. & H. 

 Erythroxylon burmanicum Griff., and Walsura robusta Eoxb., in the 

 Philippines. 



One entire set of the material on which the following article is based 

 is preserved in the herbarium of the Forestry Bureau in Manila, and so 

 far as duplicates were available one set deposited in the herbarium of 

 the Botanical Institute at Buitenzorg and one set in the United States 

 National Herbarium at Washington, all this duplicate material being 

 distributed under the numbers cited in this article.
