ply racemose, leaf-opposed and in the uppermost axils, up to 
13 cm long. Capsules (somewhat immature) subglobose, about 
1 cm in diameter, composed of three cocci, outside granulose- 
glandular, the orange-yellow glands more or less obscured by 
the very dense, cinereous, stellate-puberulent indumentum, 
densely and softly echinate, the processes about 3 mm long. 
British North Borneo Marauti watershed, near Tawau, Villamil S76, 
June 1, 1917, in forests at low altitudes. Locally known as limpasoh-suluk. 
The alliance of this species is manifestly with the Javan Mallotus 
glaberrimus Muell.-Arg., which has also been reported from Borneo. It 
differs in its elenticellate branches, caudate-acuminate, entire leaves, which 
have no marginal glands in the upper part, and fewer lateral nerves.

TARRIETIA Blume 
TARRIETIA BORNEENSIS sp. nov. 
Arbor circiter 30 m alta, partibus junioribus exceptis glabra; 
foliis unifoliolatis, ellipticis ad oblongo-ellipticis, coriaceis, bre- 
viter obtuse acuminatis, basi acutis ad subrotundatis, usque ad 
14 cm longis, glabris, nitidis, supra dense et minute foveolatis,

A tree about 30 m high, the trunk about 60 cm in diameter, 
glabrous except the very young parts. Branches brownish, 
terete, glabrous, the growing branchlets minutely and densely 
subferruginous-puberulent-lepidote as are the very young peti- 
oles. Leaves simple, elliptic to oblong-elliptic, brown, of about 
the same color on both surfaces, shining when dry, coriaceous, 
9 to 14 cm long, 4 to 6 cm wide, glabrous, the upper surface 
minutely and densely foveolate, apex shortly and bluntly acumi- 
nate, base rounded to acute ; lateral nerves about 12 on each side 
of the midrib, spreading, slightly curved, prominent; petioles 
2 to 3 cm long. Peduncles in fruit up to 6 cm long, axillary, 
solitary, each bearing about three umbellately disposed fruits. 
Fruits oblong-ovoid, about 1.5 cm long, glabrous, the wings coria- 
ceous, brown, shining, reticulate, glabrous, inequilaterally oblong- 
obovate, subfalcate, rounded at the apex, up to 7 cm long and 
3 cm wide. 
British North Borneo, near Sandakan, Villamil 3, August 14, 1915, 
on forested slopes, altitude 40 to 70 meters. 
This characteristic species is manifestly allied to Tarrietia simplici folia 
Mast, of the Malay Peninsula, the few known species of the genus with 
simple leaves being Tarrietia kunstleri King and T. simplicifolia Mast, of
