all or nearly all the dark-colored, flagrant pitch mentioned by Blanco, used 

 by the natives for torches and for calking boats. 



The specific name villosa was adopted by Blume because the two names 

 previously used by Blanco were untenable, he having erroneously identified 

 the species, first with Canarium commune Linn., and later with Canarium 

 pimela Koen., neither of these species extending to the Philippines. Miquel 

 transferred Blume's specific name to Canariopsis, and F.-Villar first trans- 

 ferred the name to Canarium, and accordingly should be cited as the 

 authority. Regarding the identity of Canarium cuminriii Engl., with 

 Canarium villosum (Blume) F.-Vill., there can be little doubt, and Engler 

 in his monograph of the Burseracece, judging from a single number of 

 Cuming's collection, with no data as to the native names or physical prop- 

 erties of the tree, suggested that perhaps Pimela villosa Blume was 

 referable to Canarium cumingii. 



In working over the Canarium material in the Herbarium of this Bureau, 

 it seems evident that it will be necessary to reduce several other species to 

 Canarium villosum, a matter which can be determined by some future mono- 

 grapher. The species are mentioned below. 



Canarium luxurians Eng. forma monstrosa Engl, in DC. Monog. Phan. 

 4:146. 



This species and form was based on a single number of Cuming's Phil- 

 ippine collection, and is represented by the following specimens in the 

 herbarium of this Bureau : 



Philippines: No. 796 Cimiing (cotype), Luzon. Province of Rizal. Boso- 

 boso (2821 Merrill), July, 1903, T., Pachainguin; same locality (1861 

 Ahern's collector). September, 1904, T., Palasahinguin ; Tanay (2.348 Mer- 

 rill), May, 1903, T., Pachaittgin. Province of Tayabas, without locality, 

 native collector, November, 1904, T., Pagsanguin. Guimaras Island (282 

 Gammill), January, 1904, V., Salong. 



Engler has placed Canarium luxurians monstrosa in the section Triandra, 

 while C. cumingii =^C. villosum, is in the section Eucanarium. Perkins^ 

 under Canarium carapifolium, has suggested that the section Triandra must 

 be abandoned, as she found flowers of Canarium carapifolium with 3, 4, and 

 6 stamens. It is here suggested that Canarium luxurians monstrosa is only 

 a form of Canarium villosum, as the vegetative characters and native names 

 are the same, and that the peculiar, dense, many branched inflorescence of 

 the former may be due to the work of insects or to some parasitic fungus. 

 I have fovmd the same abnormal type of inflorescence on Diospyros (448 

 Ahern's collector; 1654 Merrill) Province of Rizal, Luzon. Normal flowers 

 of Canarium luxurians forma monstrosa have not been foviml. 



Canarium juglandfolium Perk. Frag. Fl. Philip. 93. 1904. The type of 

 this species is No. 1974 Merrill, Subic, Province of Zambales. Luzon. T., 

 Pagsainguin. 



Canarium thyrsoideum Peik. 1. c. 07. No. 2119 Merrill. Pitogo. Prov- 

 ince of Tayabas, Luzon, April, 1903, T.. Anangi. Pola. Mindoro (2256 

 Merrill), May, 1903, T., Pasahinhin.
