Arg. from which it is at once distinguished by its conspicuously 
impressed nerves and reticulations, and by its very slender, 
greatly elongated inflorescences, both the staminate and pistil- 
late flowers even in young inflorescences being widely scattered 
and not densely crowded as in A. cumingii. 
ANTIDESMA ILOCANUM sp. nov. 
Frutex vel arbor parva, ramulis inflorescentiisque castaneo- 
pubescentibus ; foliis lanceolatis, chartaceis, 15 ad 20 cm longis, 
subtus ad costa nervisque leviter pubescentibus, acuminatis, 
basi plerumque obtusis, nervis utrinque circiter 12, perspicuis; 
stipulis linearis vel lineari-lanceolatis, 6 ad 8 mm longis ; racemis 
2 axillaribus, solitariis, circiter 20 cm longis; fructibus inae- 
quilateraliter ovoideis, glabris, 9 mm longis, obtusis, stigmate 
terminale. 
A shrub or small tree, the young branchlets and inflorescences 
castaneous-pubescent. Leaves lanceolate, chartaceous, 15 to 20 
cm long, 3 to 4.5 cm wide, pale-olivaceous and shining when dry, 
the lower surface brownish and sparingly castaneous-pubescent 
on the mfdrib and nerves, ultimately glabrous or nearly so, some- 
what narrowed upward to the acuminate apex, the acumen with 
a short mucro, base slightly narrowed, rounded to obtuse ; lateral 
nerves about 12 on each side of the midrib, prominent on the 
lower surface, arched, anastomosing, the reticulations distinct; 
petioles stout, 5 to 7 mm long, when young castaneous-pubescent, 
soon becoming glabrous ; stipules linear or linear-lanceolate, acu- 
minate, 6 to 8 mm long. Pistillate racemes axillary, simple, 
about 20 cm long, the rachis rather stout, castaneous-pubescent, 
marked with numerous scars of fallen pedicels, the pedicels pu- 
bescent, 2 to 3 mm long. Sepals 5, pubescent, about 1 mm long. 
Fruits ovoid, inequilateral, glabrous, somewhat compressed, 
about 9 mm long, the base broadly rounded, apex obtuse, when 
dry prominently reticulate-rugose; stigmas terminal.

The alliance of this species is manifestly with Antidesma 
cumingii Muell.-Arg., from which it is readily distinguished by 
its relatively much-narrowed leaves and its very narrow stipules.
