or less, the branches ascending, the lower ones often 15 cm. long, densely 

 pubescent with gray hairs. Flowers small, yellowish. Sepals imbricate, 

 broadly ovate, obtuse or subacute, 3 mm. long, 2.5 mm. wide, densely 

 pubescent, the three outer ones inclosing the two inner. Petals 8 mm. 

 long, 3.5 mm. wide, obtuse. Stamens 15, in two series, the filaments 

 broad, 1 mm. long; anthers broadly ovate, 0.6 mm. long, the appendix to 

 the connective slender, as long as the anther. Ovary pubescent, the stylopod 

 very obscure or wanting. Style slender, 1.5 mm. long. In the fruit all 

 the sepals are accrescent, the three outer ones being 4.5 cm. long, and 

 8 to 10 mm. wide, obtuse, the two inner ones about 2 cm. long or less, 

 and 3 mm. wide. 



A tree growing in the hill forests, at from 100 to 800 m. above the sea, 

 reaching a height of 50 m. and a diameter of 1 m. more or less. It is 

 especially common in the forests of the Province of Bataan and is univer- 

 sally known to the Tagalogs .of that Province as Tanguili, and on account 

 of its great size is much prized by them for making canoes; facts also 

 noted by Blanco, in the original description of the species. 



Shorea polysperma belongs in the section Pinanga, and is represented by 

 the following specimens, all from the Lamao River region, Mount Mari- 

 veles, Province of Bataan, Luzon: No. 606 (Forestry Bureau), collected 

 by Barnes, April, 1904; Nos. 734, 784, and 819 (Forestry Bureau), 

 collected by Borden, May, 1904 (flower); No. 1410 (Forestry Bureau), 

 collected by Borden, July, 1904 (fruit); No. 132 (Whitford), May, 1904 

 ( flower ) . 



Blanco's material, on which this species was based was in part from 

 Balanga, Province of Bataan, and his description applies to the above 

 specimens except in one or two particulars. The petioles are not particu- 

 larly short, as described by Blanco, nor is the fruit more than one-seeded, 

 it being described by Blanco as follows, "Baya? con dos? aposentos, y en 

 cada uno algunos semillas," it being evident that either Blanco had 

 mutilated or very imperfect fruits, or that he was not sure that his 

 fruits were really from this tree. Inasmuch as the fruit of Shorea polys- 

 perma is one-seeded, and not with several seeds as described by Blanco, 

 his specific name does not well apply to the species. 

 Dipterocarpus lasiopodus Perkins, Frag. Fl. Philip. 22. 1904. 



The fruit of this species is figured by Vidal, Sinopsis, Atlas, t. 14- f. D., 

 under the name Dipterocarpus pilosus Roxb., this figure being mentioned 

 by Brandis 1 sub. Dipterocarpus affinis, accordingly the following synonym 

 should be added. Dipterocarpus pilosus, F.-Vill. Nov. App. 20. 1880; 

 Vidal, Sinopsis, Atlas, t. 14. f, D. 1883, non Roxb. 

 Hopea acuminata sp. nov. Petalandra. 



A tree reaching a height of 40 m., with broadly lanceolate, narrowly 

 acuminate, glabrous leaves, 8 cm. long or less, and small flowers in unilateral 

 racemes, which are arranged in terminal and axillary panicles. Branches 

 nearly black when dry, glabrous, striate. Leaves 4 to 8 cm. long, 2 to 3 

 cm. wide, submembranous, shining above, the base inequilateral, rounded
