the pedicels thickened, densely cinereous-tomentose, 3 to 5 mm 
long, the bracteoles acicular from a broadened base, about 3 
mm long, two or three subtending each pedicel. Fruits about 
1 cm in diameter, each composed of two cocci, pale-brownish 
when dry, globose, densely and minutely tomentose, and densely 
covered with stiff, slender, glabrous spine-like processes 3 to 5 
mm in length. 
British North Borneo, Marutai watershed at Tawau, Villamil S70, 
May 28, 1917, on damp slopes at low altitudes. 
This species is very closely allied to the Philippine Mallotus auriculatus 
Merr., from which it is distinguished by its thicker, entire, rather more 
numerously nerved leaves, which are rather densely glandular beneath; in 
having but a single pair of basal glands; and in its densely tomentose 
cocci, which are much more densely spiny, the spines distinctly longer 
than in the Philippine form.

A shrub about 3 m high, nearly glabrous (fruits excepted), 
the younger branchlets and the inflorescences sparingly and 
deciduously tomentose. Branches terete, pale-brownish, gla- 
brous, not at all lenticellate, the branchlets angular-striate, pale 
reddish-brown. Leaves opposite, those of each pair slightly un- 
equal in size, membranaceous to subchartaceous, pale-olivaceous, 
shining, oblong to broadly oblong-oblanceolate, entire, 15 to 25 
cm long, 5 to 7 cm wide, the upper surface smooth, glabrous, 
not at all glandular, the lower with widely scattered, distinct, 
orange-yellow to brown, granulose glands, the apex slenderly 
caudate-acuminate, the acumen up to 3 cm in length, the base ob- 
tuse, distinctly but minutely cordate, and with two distinct glands 
on the upper surface; lateral nerves 6 to 9 on each side of the 
midrib, very prominent on the lower surface, curved-ascending, 
anastomosing, the primary reticulations lax, subparallel, prom- 
inent; petioles 2 to 6 cm long, glabrous. Infructescences sim-
