Philippines it differs, among other characters, in its decidedly larger, 
broader, more numerously nerved leaves.

Arbor circiter 25 m alta, inflorescentiis exceptis glabra; 
ramis ramulisque teretibus, lenticellatis ; foliis chartaceis vel 
subcoriaceis, oblongis, usque ad 25 cm longis, breviter acurni- 
natis, nervis utrinque circiter 18, subtus perspicuis; inflores- 
centiis $ e axillis defoliatis, paniculatis, usque ad 13 cm longis, 
plus minusve ferrugineo-pubescentibus ; floribus pedicellatis, 3-, 
rariter 4-meris, circiter 1.7 mm diametro, in ramulis ultimis 
dense confertis. 
A tree reaching a height of about 25 m, glabrous except the 
inflorescence. Branches terete, stout, brownish and striate when 
dry, lenticellate, the branchlets also terete, glabrous. Leaves 
firmly chartaceous or subcoriaceous, oblong, 17 to 25 cm long, 
4.5 to 8 cm wide, slightly shining and usually more or less 
brownish when dry, the apex shortly acuminate, the base acute 
or obtuse ; nerves about 18 on each side of the midrib, prominent 
beneath, anastomosing, the reticulations obsolete or nearly so, 
very lax; petioles about 1 cm long. Staminate inflorescence 
from the axils of fallen leaves, paniculate, pyramidal, 10 to 13 
cm long, the lower branches spreading, often 5 cm long, the 
upper few gradually shorter, the rachis, branches and especially 
the ultimate branchlets more or less ferruginous-pubescent, the 
flowers densely crowded on the ultimate branchlets, their pedicels 
less than 1 mm long. Buds globose, less than 2 mm in diameter. 
Mature flowers 1.5 to 1.8 mm long, 3-, rarely 4-merous, the lobes 
broadly ovate, acute, about 1 mm long, quite glabrous. Stamens 
about 14, the anthers entirely united into a sessile, globose or 
depressed-globose mass about 1 mm in diameter. Immature 
fruits oblong, about 2 mm long, glabrous.

I am disposed to place this species in the section Pyrrhosa, allied to 
H. kingii, H. amygdalina, and H. glabra. It strongly resembles, however, 
H. irya and allied species, but the anthers seem to be entirely united, and 
the flowers are never 2-merous. This is the form previously identified by 
me as Horsfieldia ardisiifolia Warb., 8 the determination having been made
