Sideroxylon angustifolium {Palaquium. angustifolium Merrill, Govt. Lab. 

 Publ. 17:43. 1904.) 



Additional material of this species, in flower, has been collected from 

 the same locality from which the type of Palaquim angustifolium was 

 secured, from an examination of which a reexamination of No. 3744 Merrill 

 the species must go to Sideroxylon. Calyx 5-partite, not 6, as in the origi- 

 nal description, the lobes ovate, acute, 5 mm. long, densely ferruginous 

 pubescent. Corolla glabrous, 3 mm. long (immature) 5-lobed, the lobes 

 oblong-obovate, truncate. Stamens 5, the filaments short, the anthers ovoid, 

 nearly 1.5 mm. long; staminodes 2 to 2.5 mm. long, about 0.4 mm. wide, 

 linear-oblong, truncate, obtuse or somewhat retuse, not lobed or lacerate. 

 Ovary ferruginous pubescent, 5-celled; style glabrous, stout, channeled, 3 

 mm. long. 



Mount Mariveles, Province of Bataan, Luzon (3744 Merrill), January, 

 1904 (fruit), type of Palaquium angustifolium j (1166 Whitford), same 

 locality, March, 1905 (flower). This species was originally described from 

 fruiting specimens, and the calyx erroneously characterized as 6 lobed in- 

 stead of 5 lobed as it really is. 



Sideroxylon macranthum sp. nov. 



A large tree, reaching a height of 30 m., with oblong-obovate, long 

 petioled, obtuse to somewhat acuminate leaves, which are more or less 

 rusty tomentose when young, becoming glabrous, and numerous flowers 

 about 5 mm. long, fasciculate in the axils of the leaves, the staminodes 

 entire. Branches rather stout, brownish gray, striate, more or less ferru- 

 ginous pubescent, becoming glabrous, the leaf scars rather prominent. 

 Leaves subcoriaceous, 11 to 18 cm. long, 4 to 8 cm. wide, shining, the 

 base acute, often somewhat decurrent; nerves 10 to 11 pairs, prominent, 

 the secondary ones and reticulations rather obscure; petioles 2 to 4.5 cm. 

 long, at first rusty tomentose, becoming glabrous. Flowers creamy white, 

 in fascicles of from 3 to 5, crowded in the axils near the apices of the branch- 

 lets, the buds subglobose, obtuse, the pedicels 3 to 5 mm. long and with 

 the sepals imiformly densely rusty pubescent. Sepals 5, imbricate, orbi- 

 cular-ovate, obtuse, 5 mm. long. Corolla glabrous, cylindrical, equaling 

 the sepals, 5-lobed, the lobes 2 mm. long, ovate, obtuse-truncate. Stamens 

 5, included, the anthers nearly 1 mm. long, obtuse; staminodes lanceolate, 

 blunt, entire, about 1 mm. long. Ovary densely villous, 5-celled; style 

 stout, about 1 mm. long. Fruit globose, about 3.5 cm. in diameter, decidu- 

 ously ferruginous pubescent, 2 to 3 seeded. 



Type specimens : (2741 (flower) and 1809 (fruit) Borden ), Lamao River, 

 Province of Bataan, Luzon, March, 1905, and September, 1904; (51 Barnes, 

 same locality), October, 1903; also apparently No. 2608 Merrill, Pagbilao, 

 Province of Tayabas, Luzon. This species was identified by the author, 

 when received, as Sideroxylon duclitan Blanco, but is certainly not that 

 species, and is apparently undescribed. The species previously described 

 by the author as Sideroxylon ramiflorum is certainly a synonym of Side- 

 roxylon duclitan Blanco.
