when fresh, brown and shining when dry, reticulate, with few, 

 short, scattered hairs, somewhat inequilateral, compressed, base 

 somewhat inflated, rounded, about 8 mm long and 5.5 mm wide ; 

 stigmas terminal. 



Sarawak, Sungei Tingei, Foxworthy U71, June 25, 1908, at the edge 

 of a tidal stream (type) ; Retuh, Sadong, Native collector 25S5 (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 

 foliis 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-
