a small, deciduous, oblong, obtuse, 1 mm long bracteole at the 
upper one-fourth or one-third. Staminate flowers small, not 
exceeding 3 mm in length, the buds ferruginous-puberulent out- 
side, glabrous within, subglobose or somewhat 3-angled, 3-, 
rarely 4-merous, the calyx-segments thick, ovate, 3 mm long or 
less, acute. Staminal-disk stipitate, glabrous, the stipe less than 
1 mm long, bearing on the margins of the disk 8 or 9, radiately 
disposed, 0.5 mm long anthers. Pistillate flowers and fruits 
unknown.

A species apparently not closely allied to the other Philippine represent- 
atives of the genus, well characterized by its unusually small staminate 
flowers and by its small leaves.

Arbor 12 ad 15 m alta, partibus .iunioribus fructibusque 
densissime ferrugineo-tomentosis ; foliis lanceolatis vel oblongo- 
lanceolatis, 8 ad 12 cm longis, coriaceis, acuminatis, basi acutis

que 12 ad 15; floribus 8 axillaribus, parvis, 3-meris, extus 
densissime ferrugineo-tomentosis, disco stamineo glabro, brevi-

A tree 12 to 15 m high, the young branchlets and leaves very 
densely ferruginous-tomentose as are the buds and young fruits. 
Branches grayish-brown, striate, glabrous. Leaves lanceolate 
to oblong-lanceolate, coriaceous, 8 to 12 cm long, 2 to 3 cm wide, 
entire, rather slenderly acuminate, base acute or obtuse, the 
upper surface glabrous, shining, the lower surface pale, puberu- 
lent, ultimately becoming nearly glabrous; petioles when young 
ferruginous-tomentose, later puberulent, 8 to 15 mm long; 
nerves 12 to 15 on each side of the midrib, prominent, anasto- 
mosing, the reticulations not prominent. Male flowers on short, 
axillary, solitary tubercles, the whole inflorescence ferruginous- 
tomentose, 1 cm long or less. Pedicels short. Flowers crowded, 
in bud globose or ovoid, the perianth-segments 3, ovate, about 
3 mm long, the bracteoles ovate, deciduous, 2 mm long. Stam- 
inal-disk shortly stipitate, glabrous, bearing on the margins 6 
radiately spreading anthers about 0.5 mm long. Fruit (imma- 
ture) ellipsoid, 1.5 to 2 cm long, densely ferruginous-tomentose.

its smaller, fewer-nerved, apparently always entire leaves, the younger
