longo-ovatis vel oblongo-lanceolatis, 12 ad 22 cm. longis, 4.5 ad 
9 cm. latis, aequilateralibus, basi abrupte angustatis, acutis, apice 
acuminatis, hervis utrinque circiter 12 perspicuis; fructibus sub- 
globosis, circiter 5.5 cm. diametro, anthocarplis numerosis, leviter 
productis, ovoideis, obtusis, circiter 1 mm, longis, uniformiter fer- 
rugineo-furfuraceo-hirsutis ; seminibus numerosis, circiter 13 mm. 
longis, perianthi1 segmentis leviter hirsutis. Species A. rigidae 
affinis, sed foltis elabris et anthocarpiis brevissime productis. 
A large tree glabrous except the very obscurely puberulent 
branchlets and the furfuraceous-hirsute tips of the anthocarps; 
branches brown, rugose, terete, 5 to 6 mm. in diameter, the younger 
branchlets frequently only 3 mm. in diameter. Leaves equilateral, 
entire, coriaceous, glabrous, shining, oblong-ovate to oblong-lanceo- 
late, 12 to 22 cm, long, 4.5 to 9 cm. wide, ‘the hase rather ‘abruptly 
narrowed, acute, usually gradually narrowed upward to the short, 
blunt-acuminate apex, brownish or brownish-olivaceous when dry, 
smooth, shining; lateral nerves about 12 on each side of the mid- 
vento), not impressed on the upper surface, very prominent on the 
lower surface, anastomosing near the margins, the primary reticu- 
lations distinct; petioles about 3 cm. lone, 2.0 to 8 mm. in dia- 
meter, glabrous. Mature or nearly mature fruits subglobose, the 
base often somewhat cordate, about 5.5 cm. in diameter, their 
peduncles stout, 3 to + em. in length, the tips of the anthocarps 
very numerous, nee blunt, about 1 mm. long, the outer surface 
of the fruit uniformly furfuraceous-hirsute, the indumentum fer- 
ruginous. Seeds ra ither numerous, a about i3 mm. long, the accres- 
cent perianth segments more or fess areuite,

Clemens 10770, November 27, 1915. In forests along trails. ‘his 
species belongs in the group with, and is manifestly allied to Arto- 
carpus rigida Blume, from which it is readily distinguished by its 
entirely glabrous leaves and by the very short tips of its anthocarps. 
Artocarpus borneensis sp. nov. 
Arbor circiter 10 m. alta, ramis teretibus, circiter 5 mm. dia- 
metro, ramulis leviter pubescentibus vel furfuraceis: foliis sub- 
coriaceis, glabris, nitidis, ellipticis vel oblongo-ellipticis, integris, 
aequilateralibus, 9 ad 14 em. longis, apice abrupte acuminatis, basi 
rotundatis vel late acutis, nervis utrinque 10 vel 12, perspicuis; 
inflorescentiis axillaribus, solitarits, ¢ oblongo-obovoideis, 12 mm, 
longis, brevissime pedunculatis, bracteolis peltatis, dense imbri- 
eatis, cupreis; fructibus subglobosis, + cm. diametro, laevibus, dense 
cupreo-furfuraceo-lepidotis, anthocarpits haud productis; seminibus 
paucis, 10 ad 12 mm. longis. 
A tree about 10 m. high, mature fruits densely and un onaadl 
furfuraceous-lepidote, the indumentum cupreous. Branches terete, 
glabrous, about 5 mm. in diameter, the very young branchlets ob- 
securely pubescent or shghtly furfuraceous. Leaves subcoriaceous, 
glabrous, entire, elliptic to oblong-elliptic, 9 to 14 cm. long, 4 to 8
