diametro, confertis; sepalis ,ovatis, 3.5 mm longis, utrinque 
pubescentibus; petalis exterioribus elliptico-ovatis, utrinque an- 
gustatis, 6 mm longis, interioribus arcuatis, 7 mm longis; 
staminibus 12; carpellis 5, pubescentibus. 
A tree about 10 m high, the branchlets, petioles, and midrib 
and nerves on the lower surface of the leaf sparingly appressed- 
pubescent, the inflorescences densely appressed-pubescent with 
gray hairs. Leaves oblong to oblong-elliptic, chartaceous, 15 
to 22 cm long, 6.5 to 9 cm wide, base rounded to obtuse, apex 
broadly acuminate, the acumen blunt, sometimes apiculate; lat- 
eral nerves 8 to 12 on each side of the midrib, rather prominent 
beneath, ascending, anastomosing, the reticulations slender, not 
prominent; petioles about 5 mm long. Inflorescences axillary 
or extra-axillary, of many-flowered fascicles or sometimes of 
congested short cymes, the inflorescences 4 to 5 cm in diameter, 
with from 25 to 40 flowers. Flowers yellow, odorless, their 
pedicels 1.5 to 2 cm long, rather slender, the median bracteole 
oblong-ovate, acuminate, 4 mm long. Sepals ovate, 3.5 mm 
long, 3 mm wide, acute or slightly acuminate, pubescent on both 
surfaces. Outer petals elliptic-ovate, narrowed at both ends, 
pubescent, acute or slightly obtuse, 6 mm long, 5 mm wide; 
inner petals arched, about 7 mm long, the claw stout, glabrous, 
3 mm long, the limb subrhomboid, 4 to 5 mm wide, pubescent 
on both surfaces above. Stamens about 12, about-1 mm long. 
Carpels usually 5, oblong, inequilateral, pubescent, 1.2 mm long. 
British North Borneo, Tawao, Agama 544, May 11, 1918. In 
flat country along Brantion River, slightly above sea level, with 
the Malay name banitan. 
The striking character by which this species may be distin- 
guished is its very many-flowered inflorescences, some of which 
contain at least forty flowers; they are either in fascicles or 
in greatly congested, sometimes short-peduncled cymes.
