NEW OR NOTEWORTHY BORNEAN PLANTS. 185 
P_ subcordata Blume, in its more numerously nerved leaves which 
are symmetrical, not inequilateral at the base, its much longer 
peduncles, and its apiculate fruits. 
Polyalthia xanthopetala sp. nov. 
Abor 9 vel 12 m. alta, ramulis dense ferrugineo-pubescentibus ; 
folus oblongis vel late oblongo-oblanceolatis, 18-25 em. longis, 
subcoriaceis, nitidis, brunneo-olivaceis, costa utrinque pubescentibus, 
acuminatis, basi late acutis vel subrotundatis, nervis utrinque 
tirciter 13, subtus perspicuis; floribus 7 em. longis, fasciculatis, 
pedicellatis, caulinis et in ramis vetustioribus; petalis subaequalibus, 
lanceolatis, circiter 7 cm. longis, 10-12 mm. latis, acuminatis, 
leviter pubescentibus; carpelis numerous, oblongis, pubescentibus, 
1-ovulatis; fructibus subglobosis vel ovoideis, 2-2.5 cm. diametre, 
«lense pubescentibus. 
A tree 8 to 10 m. high, the branchlets slender, densely 
ferruginous-puhescent, the ultimate ones 1.5 mm. in diameter. 
Branches rugose when dry, glabrous, dark-colored. Leaves oblong 
to broadly oblong-lanceolate, subcoriaceous, 18 to 25 cm. long, 4 
to 8 cm. wide, rather conspicuously acuminate, base broadly acute 
to somewhat rounded, the upper surface olivaceous, shining, 
glabrous except for the pubescent midrib, the lower surface some- 
what paler, glabrous, or the midrib usually somewhat pubescent ; 
lateral nerves about 13 on each side of the midrib, prominent on 
the lower surface, somewhat curved, scarcely anastomosing, the 
reticulations rather close, slender; petioles 5 to 10 mm. long, 
ferruginous-pubescent, in age glabrous. Flowers vellow, about 7 
em. long, fascicled on the trunk and on the branches below the 
leaves, few in a fascicle, their pedicels densely ferruginous- 
pubescent, 1.5 to 2.5 cm. long.’ Sepals triangular-ovate, acute, 
pubescent, 5 to 6 mm. long. Petals subequal, distinctly pubescent 
at the base outside, very sparingly pubescent above or glabrous 
inside, lanceolate, about 7 cm. long, 10 to 12 mm. wide, shghtly 
acuminate. Stamens indefinite, oblong, 1.5 mm. long, the con- 
‘nectives produced, rounded, truncate. Carpels many, oblong, 
densely appressed-pubescent, 1.3 min. long, 1-ovulate; styles some- 
what club-shaped, 2 mm. long, deciduous. Mature fruits sub- 
globose or somewhat ellipsoid, about 2 to 2.5 cm. in diameter, 
densely ferruginous-pubescent as are the fruiting pedicels, the 
torus in fruit about 1 cm. in diameter.

(type), 1412, 1320, Agama 1027, October and November, 1920. 
In damp forests at low altitudes. A species apparently allied to 
Polyalthia lateriflora King, but at once distinguishabie, among other 
characters, by its densely pubescent fruits.
