pubescent young branchlets and rachis of the short racemes. 
Branches slender, terete, gray or reddish-brown. Leaves alter- 
nate, firmly chartaceous, subolivaceous, shining, oblong, oblong- 
elliptic or oblong-obovate, 10 cm long, 4 to 7 cm wide, apex 
rather prominently acuminate, the acumen blunt, base acute 
to somewhat rounded, not or very obscurely glandular, the mar- 
gins distantly glandular-crenulate ; lateral nerves 8 to 13 on each 
side of the midrib, prominent, anastomosing, the reticulations 
lax, distinct; petioles 2 to 4 mm long; stipules ovate, obtuse, 
about 4 mm long. Staminate racemes axillary, solitary, very 
short, few-flowered, the rachis 1 cm long or less, usually but one 
flower maturing at a time, the bracteoles oblong, about 4 mm 
long, persistent, the upper inflorescences sometimes reduced to 
mere fascicles. Pedicels up to 2.5 cm long, thickened upward, 
slender. Sepals unequal, orbicular-obovate, margins ciliate, 
about 3 mm in diameter. Petals free, glabrous, obovate, rounded, 
5 to 6 mm long. Stamens about 12, the exterior nine free, their 
filaments broad, flat, about 3 mm long, the interior three stamens 
with their filaments united for nearly their entire length. Rudi- 
mentary ovary none. 
Sarawak, Baram District, Baram, Hose 244, March, 1895. 
Apparently not closely allied to any of the previously described species, 
well characterized by its short racemes, its short petioles, its long pedicels, 
and its broad flat filaments.

as tuchung. 
I consider that Doctor Pax is quite correct in reducing my Ostodes 
serrato-crenatus to 0. macrophyllus. The known range of the species is 
now Malacca, Pahang, Borneo, Sibuyan, and the Provinces of Laguna 
and Cagayan, Luzon.
