stigmas terminal. 
Sarawak, Sungei Tingei, Foxworthy 571, June 25, 1908, at the edge 
of a tidal stream (type) ; Retuh, Sadong, Native collector 2535 (Bur. 
Sci.), February-June, 1914, from debris attached apparently from the banks 
of streams subject to inundation in times of flood. 
This species belongs in the group with Antidesma tomentosum Blume, 
and is well characterized by its narrow, somewhat inequilateral leaves, 
the nerves impressed on the upper surface, very prominent on the lower 
surface, rather strongly ascending, and its pubescent branchlets, petioles, 
inflorescences, stipules, midrib, and nerves on the lower surface of the 
leaves. The fruits are very sparingly pubescent and much smaller than 
in Blume’s species. 
ANTIDESMA RUBIGINOSUM sp. nov. 
Frutex vel arbor parva, partibus junioribus stipulis subtus 
folils ramulis inflorescentiisque dense rubiginoso-pubescentibus ; 
foliis oblongis ad oblongo-lanceolatis, usque ad 15 cm longis, 
tenuiter acuminatis, basi acutis, nervis utrinque 6 vel 7, pro- 
minentibus, curvato-adscendentibus ; stipulis lanceolatis, tenuiter 
acuminatis, circiter 1 cm longis ; inflorescentiis ? racemosis, rari- 
ter depauperato-paniculatis, racemis pedunculatis, 2 ad 3 cm 
longis; floribus 4-meris, confertis, breviter pedicellatis, disco 
glabro, cupuliforme, truncato, prominente; ovario glabro, stylis 
terminalibus. 
A shrub or small tree, prominently rubiginous-pubescent with 
rather soft, short hairs. Branches slender, terete, pale-gray, 
glabrous, the young branchlets densely rubiginous-pubescent as 
are the petioles, inflorescences, and the midrib and nerves on the 
lower surface of the leaves. Leaves oblong to oblong-lanceolate, 
firmly chartaceous to subcoriaceous, 9 to 15 cm long, 2.5 to 4 
cm wide, narrowed below to the acute base and above to the 
slenderly acuminate apex, the acumen tipped by a long and 
slender apiculus, the upper surface dark-colored when dry, glab- 
rous, the lower dark-brown, prominently rubiginous-pubescent 
on the midrib and nerves and with fewer hairs scattered over 
the surface; lateral nerves 6 or 7 on each side of the midrib, 
curved-ascending, prominent, anastomosing; petioles about 2 
mm long; stipules narrowly lanceolate, slenderly acuminate, ru- 
biginous-pubescent, often somewhat inequilateral or slightly 
falcate, about 1 cm long and 2 to 3 mm wide. Pistillate racemes 
spikelike, axillary, solitary, the upper ones sometimes with a 
single branch, densely rubiginous-pubescent, peduncled, 2 to 3 
cm long, the upper part densely flowered. Pedicels stout, pubes-
