STERCULIACE.i^. 



Sterculia crassiramea sp. nov. 



A large tree with entire, oblong-ovate, cordate leaves, which are. densely 

 stellate-pilose beneath, and axillary many-flowered panicles, crowded with 

 the leaves at the ends of the thickened branches. Branches grayish-browTi, 

 glabrous, the branchlets much thickened, especially at the pubescent tips. 

 Leaves 10 to 22 cm. long, 8 to 16 cm. wide, the base broadly cordate, very 

 slightly narrowed, the apex acute or slightly acuminate, the upper surface 

 shining, glabrous, except for a few scattered stellate hairs, the under surface 

 very densely light brown stellate-pilose throughout; basal nerves 5, prom- 

 inent, with usually 2 additional short, obscure, marginal nerves, lateral 

 nerves 8 or 9 on each side, prominent, straight, ascending, the reticulations 

 rather lax, prominent beneath; petioles 3 to 7 cm. long, very densely pilose; 

 stipules deciduous, subulate, pilose, about 1 cm. long. Panicles densely 

 rusty-pubescent throughout, 12 to 18 cm. long, the branches spreading, 

 about 3 cm. long. Flowers yellow, 4 mm. long. Calyx densely rusty- 

 pubescent outside, purplish-pubescent within, 5-lobed, the lobes ovate-acute, 

 about 25 mm. long. Staminal column slender^ 25 mm. long, bearing at 

 its cernuous apex about 8 sessile anthers. 



Type specimen No. 1882 (Forestry Bureau), Ahern's collector, Bosoboso, 

 Province of Rizal. Luzon, October 15, 1904. This is undoubtedly the 

 species enumerated by F. Villar^ as Sterculia macrophylla Vent. T., 

 Banilad. 

 Sterculia obovata sp. nov. 



A small tree about 5 m. high, with narrowly obovate, abruptly acuminate, 

 more or less pubescent leaves 10 cm. long or less, the inflorescence panicu- 

 late, fascicled at the tips of small specialized, leafless branchlets which are 

 borne on the branches below the leaves. Branches light gray, glabrous, 

 striate, the tips more or less ferruginous tomentose. Leaves 7 to 10 cm. 

 long, 3.5 to 4 cm. wide, widest at the upper two-thirds, the apex abruptly 

 short acuminate, tapering below to the abruptly acute or somewhat narrowly 

 rounded base, the upper surface glabrous, except for the pubescent midrib, 

 the lower surface with scattered stellate ferruginous hairs on the midrib, 

 nerves, and reticulations; nerves about 8 pairs, prominent beneath, obscure 

 above, the reticulations prominent beneath; petioles 1 cm. long, densely 

 ferruginous tomentose; stipules lanceolate, acuminate, ferruginous pubes- 

 cent. 6 to 7 mm. long. Panicles 7 cm. long or less, the axis, branches, and 

 outside of the calyx densely rufous tomentose, the longest branches about 

 1.5 cm., spreading, slender, bearing two or three flowers only. 31ale flowers 

 obovoid, the calyx lobes cohering by their apices, G to 7 mm. in diameter, 

 the tube shorter than the lobes, the lobes densely rufous tomentose outside, 

 whitish tomentose within, lanceolate, acute, 5 to 6 mm. long. Staminal 

 column glabrous, 2 to 3 mm. long, the anthers 10, sessile, about 0.5 mm. 

 long. Female flowers and fruit not seen.
