the Malay Peninsula, and T. sylvatica (Vid.) Merr. of the Philippines. It 
is readily distinguished from T. simplicifolia Mast, by its much fewer- 
nerved leaves, from T. kunstleri King by its glabrous fruits, and from T. 
sylvatica Merr. by its leaves not being densely lepidote beneath.

rosis, bracteis linearibus, 5 ad 9 mm longis, setosis; sepalis 
leviter inaequalibus, 6 ad 7 mm longis, extus setosis, oblongo-

A shrub about 2 m high, the branches, branchlets, petioles, 
inflorescences, midrib on the upper surface, margins, and lower 
surface of the leaves conspicuously setose with slender, curved, 
spreading setae up to 5 mm in length, most of these parts also 
pubescent, the setae brownish to purplish-brown when dry, 
pink to deep-brown when fresh. Leaves chartaceous, oblong, 
narrowed to both ends, 20 to 28 cm long, 7 to 9 cm wide, apex 
slenderly and sharply acuminate, base narrowed, obtuse to ob- 
scurely cordate, the upper surface grayish, somewhat shining, 
smooth and glabrous except the setose midrib, the margins setose, 
the lower surface conspicuously setose on the midrib, nerves, 
and reticulations, and also somewhat pubescent; lateral nerves 
about 20 on each side of the midrib, prominent on the lower 
surface, curved, anastomosing, the reticulations subparallel, dis- 
tinct; petioles 1.5 to 2 cm long. Cymes cauline, fascicled on 
densely setose tubercles, about 5 cm long, densely setose and 
pubescent, rather many-flowered, the bracts linear, setose, 5 to 
9 mm long, the pedicels 4 to 7 cm long. Sepals oblong-ovate 
to oblong-elliptic, 6 to 7 mm long, the outer two acute, densely 
setose on the back, the inner ones slightly longer, obtuse, setose 
on the exposed portions, but glabrous on the parts covered by 
the imbricate outer sepals. Young fruit ovoid, glabrous; styles 
3, the arms about 2 mm long, united for the lower 1.5 mm.
