180 NEW OR NOTEWORTHY BORNEAN PLANTS. 
ferruginous-pubescent. Fruits numerous, ellipsoid, yellowish- 
white when fresh, brown when dry, 10 to 12 mm. long, more or less 
ferruginous- pubescent, apiculate, their pedicels pubescent, 1 to 
1.5 cm. in length. 
British North Borneo, Batu Lima and Sibuga, near Sandakan, 
Ramos 1910 (type), 1911, 1170, October and December, 1920. In 
damp forests at low altitudes. A species belonging in the group 
with Ow ymatra calycina Jang and apparently most closely allied to 
O. philippinensis Merr., from which it is distinguished by its larger, 
more numerously nerved leaves, which are brown, not glaucous 
beneath, and in its much more conspicuous and longer in- 
dumentum. | 
Oxymitra acuminata sp. noy. 
Frutex scandens, ramulis petiolisque dense adpresse fer- 
rugineo-pubescentibus; ramis glabris, nigris, ramulis 1.5 mm. 
diametro ; foliis chartaceis, oblongo-ellipticis vel anguste oblongo- 
obovatis, 13-18 em. longis, perspicue crasseque acuminatis, basi 
rotundatis, plerumque leviter cordatis, utrinque brunneis, nitidis, 
supra glabris vel ad costam nervosque parce pubescentibus, subtus 
haud glaucescentibus, vetustioribus glabris; nervis utrinque 10 
-15, subtus valde perspicuis, reticulis utrinque  distinctis; 
infructescentiis in ramulis ultimis axillaribus extra-axillaribusque, 
circiter 4 em. diametro, fructibus numerosis, ellipsoideis, apiculatis, 
1 cm. longis, leviter pubescentibus, glabrescentibus. 
A woody vine, the branchlets and petioles densely appressed- 
ferruginous-pubescent, the branches slender, terete, glabrous, 
nearly black when dry, 2 to 3 mm. in diameter, the ultimate 
branchlets 1.5 mm. in diameter. Leaves chartaceous, oblong- 
elliptic to narrowly oblong-obovate, 13 to 18 cm. long, 4.5 to 6 cm. 
wide, the apex conspicuously and rather stoutly acuminate, the 
acumen up 2 em. long, blunt, the base rounded and usually shghtly 
cordate, the upper surface brown or brownish- olivaceous, strongly 
shining, glabrous or nearly so, or the midrib and lateral nerves 
sparingly ‘pubescent, the lower surface paler than the upper, brown, 
not at all glaucous, sparingly pubescent on the midrib and nerves, 
ultimately entirely glabrous; lateral nerves 10 to 15 on each side 
of the midrib, somewhat curved-anastomosing, very prominent 
on the lower surface, the primary reticulations subparallel and 
distinct on both surfaces; petioles 5 to8 mm. long. Infructescences 
axillary and extra-axillary on the ultimate branchlets, their 
peduncles 1.5 to 2 cm. long, ferruginous-pubescent. Fruits 
numerous ellipsoid, about 1 cm. long, apiculate, sparingly pubescent 
or nearly glabrous, their pedicels somewhat thickened upward, 
pubescent, about 1 cm. long.
