Palaquium whitfordii sp. iiov. 



A tree reaching a height of 25 m. with glabrous, obovate, obtuse, 7 to 9 

 nerved leaves, and very few, axillary, solitary flowers. Branches grayish 

 brown, striate, glabrous, the ultimate branchlets appressed ferruginous 

 pubescent. Leaves 6 to 10 cm. long, 4 to 6 cm. wide, coriaceous, pale 

 when dry, tapering from above the middle to the cuneate base, the nerves 

 spreading, 8 to 10 mm. apart; petioles slightly ferruginous pubescent, be- 

 coming glabrous, 1 to 2 cm. long. Flowers solitary in the upper axils, very 

 few, usually but one on a branchlet, the pedicels and calyx appressed 

 ferruginous pubescent, the former 5 mm. long. Calyx lobes broadly trian- 

 gular ovate to suborbicular, acute or obtuse, 3 mm. long, the inner lobes 

 much thinner than the outer. Corolla 5 mm. long, the lobes 2 mm. long, 

 blunt. Stamens 4 mm. long. Ovary pubescent. 



Type specimen: Lamao River, Province of Bataan, Luzon (10L5 Whit- 

 ford), December, 1904; also from the same locality (490 Barnes), Novem- 

 ber, 1903. 



A species most closely related to Palaquium hulaancnsc Merr., but dis- 

 tinguished from that species by its broadly obovate, fewer nerved leaves 

 and few flowers. A careful examination of the tree from which Whitford 

 secured his specimens in December yielded but three branchlets, each with 

 a solitary flower, and on a second examination in January, 1905, no flowers 

 were found. An inspection of the tree from which Barnes secured his speci- 

 mens, in December, 1903, and again in December, 1904, yielded no flowers, 

 those on the specimen collected in Novembei-, 1903, being immature. This 

 tree grows in the hill forests at an altitude of about 100 m., reaching 

 a^height of 25 m. and a diameter of from 40 to 60 cm. 



Sideroxylon ahernianum sp. nov. 



A small or medium sized tree, with glabrous, coriaceous, 9 to 11 nerved, 

 narrowly oblong-ovate to elliptical-lanceolate leaves, and small, axillary, 

 fasciculate flowers. Branches light gray, glabrous, striate, the ultimate 

 branchlets more or less ferruginous pubescent. Leaves 9 to 12 cm. long, 



3 to 5 cm. wide, the apex blunt, or nearly acute, below tapering to the 

 somewhat decurrent base, the upper surface .smooth and shining, pale 

 beneath, the young leaves minutely silvery pubescent beneath, becoming 

 entirely glabrous; nerves subprominent on both surfaces, anastomosing 

 near the margin, the reticulations evident on both surfaces ; petioles at 

 first appressed pubescent, becoming glabrous, 2 to 2.5 cm. long. Flowers 



4 mm. in diameter, in axillary 5 to 25 flowered fascicles, the pedicels and 

 calyx densely silvery and ferruginous pubescent, the former 4 to 7 nun. 

 long. Calyx lobes 5, broadly ovate, 3 mm. long. Corolla lobes 5, ovate, 

 obtuse, 3 mm. long. Anthers 1.8 mm. long, the filaments short; staminodes 

 entire, lanceolate, 1 to 1.5 mm. long. Ovary pubescent. 



Type specimen: Bosoboso, Province of Rizal, Luzon (2105 Ahern's collec- 

 tor), December, 1904. A species apparently related to Sidcrosi/lon attr- 

 nuatum A. DC, but the leaves not ferruginous pubescent.
