[Enumeration of the species.] 



CONIFERE^. 



PINUS Linn. 



P. insularis Endl. Syn. Conif. 157. 1847. 

 Luzon, Prov. Benguet, 830. 

 Ilocano, Parua; Igorrote, Al-al. 

 An endemic species also known from Lepanto and Nueva Ecija. 



P. merkusii Jungh. and De Vriese, PI. Nov. Ind. Bat. Or. 5. t. 2. 

 Luzon, Prov. Zambales, 829. 

 This species is from the mountains of Zambales; also questionably reported from 



Pangasinan. 

 Borneo and Sumatra. 



P. khasya Royle ex Gord. in Lond. Gard. Mag 16: 8. 1840. 

 Luzon, Prov. Benguet, 831. 

 Igorrote, Saleng. 

 Burma. 



This species was credited to Luzon by F. Villar, Nov. App. 212, and evidently 

 correctly so, as the specimen here referred to that species agrees very well with 

 the published descriptions and figures of Royle' s Finns khasya. That this 

 species should be found in Burma and again in Northern Luzon gives some 

 cause for doubting the identity of the Burma and Luzon specimens. This species 

 is closely related to Pinus insularis Endl. 



P. sp. nov.? 



Luzon, Prov. Benguet, 832, 833. 



A species most distinct from other Philippine material, especially in the cones which 

 are much larger than in any of the above species, being 10 cm. in length. No. 

 832 has an exceedingly rough cone. It was at first proposed to describe this 

 species as new, but owing to the comparatively small amount of material, it has 

 been considered advisable to wait until more material can be secured, and com- 

 parison made with authentic Asiatic material. 



Previously but two species of Pinus have been generally credited to the Philippines, 

 although F. Villar enumerates three, while in the present small collection under 

 consideration we have four most distinct species. All these species are found 

 in the mountainous regions in Northern Luzon, at altitudes above 1,000 meters. 

 Possibly Pinus merkusii may later be found in the mountains of the southern 

 part of the Archipelago, as its range outside of the Philippines extends much 

 farther south than the province of Zambales, its only authentic locality in the 

 in the Philippines.
