ROBINSON. 
Dioecious, so far as known: staminate inflorescences 12 to 17 cm long, 
axillary, the rachis slender, angled, yellow-hirsute, the bracts or clusters 
of bracts usually 1 to 2 cm apart; bracts lanceolate, or linear-lanceolate, 
5 to 7 mm long, densely hirsute, usually accompanied by two or three 
similar bracts only 2 to 3 mm long, the flowers 10 or more to each large 
bract, clustered on very short pedicels, the pedicels after the fall of the 
flower thickened and hollowed at the apex : calyx imbricate, deeply 4- or 
5-parted, the segments unequal, ovate to ohovate, 1.5 to 2.5 mm long, 
sparingly pubescent on the outer surface, the margins entire, not glan- 
dular; petals yellowish-green, free, imbricate, 4 or 5, ovate to obovate, 
2 to 2.5 mm long; disk at full anthesis shortly cupular, the margins as 
seen from above undulate; androphore nearly 1 mm long, the anthers 
3, in all about 0.7 mm long, the connective parted nearly to the base 
and projecting shortly beyond the cells, the latter narrowly elliptic, about 
0.5 mm long, extrorse, dehiscing longitudinally; rudimentary ovary not 
present : infrutescence about 8 cm long, otherwise similar to the staminate 
inflorescence; fruiting pedicels solitary, about 1 cm long, thickened 
at the apex, hirsute, the basal recurved, the apical spreading; calyx deeply 
5-parted, the segments lanceolate to oblanceolate, 3.5 to 4.5 mm long, 
hirsute: capsule depressed-globose, less conspicuously hirsute, about 8 
mm long, over 1 cm in diameter, 3-celled, the cells 1-seeded ; seeds about 
6 mm long, 6.5 mm wide, the sides nearly flat, the dorsal surface rounded 
with rather faint longitudinal lines on the crustaceous purplish testa, 
the cotyledons about 5.5 mm wide, 1.5 mm thick, the radicle about 
0.5 mm wide and thick. 
Tree-like in habit, but not known beyond 2 m in height, with stems 
4 cm in diameter, the apex greenish, somewhat angled, brown-hirsute; 
leaves simple, alternate; petioles 12 to 35 mm long, hirsute; lamina 
submembranaceous, oblanceolate, 23 to 33 cm long, 5 to 9 cm wide, the 
base acute, the margins glandular and often crenulate, the apex abruptly 
contracted into a subacute acumen 5 to 20 mm long, upper surface 
sparingly hirsute, under surface rather densely hirsute, both very densely 
on young leaves; pairs of veins 21 to 24, arched and forming a vein 
near the margin ; stipules lanceolate, hirsute, about 1 cm long.

The two collections are not identical, although certainly very closely allied. 
Direct comparison is possible only from the leaves, and those of the type are 
much more denticulate than the other. They are also very similar to the 
following species, but the staminate perianth makes it impossible to place them 
together. Neither species is closely allied to T. philippinensis Stapf, differing 
in inflorescence and leaves; both find a near ally in T. villosus Hook, f., but 
have smaller flowers and larger and more numerously veined leaves. None of 
the flowers on the type are at the most desired stage, but the contrast between the 
youngest and oldest indicates a development similar to that in Gleistanthus. In 
the youngest there is no trace of an androphore, this being well developed' in 
over-mature flowers on the same plant.
