(SING). 
SPECIMENS EXAMINED: Malaya, Selangor, 
Gap Sempadang, 1908, Has bin (sing). 
DISCUSSION : P. attenuatus is a member of the 
section Aero stigma, as is its closest relative, the 
Malayan P. unguiculatus RidL, which has the 
leaves 21-27 mm wide, at midsection with 17- 
19 secondary veins in each half; syncarp 5.5 cm 
long; drupes 18-20 mm long; the seed 7-8 mm 
long, suprabasal; and the style 2.5-3 mm long. 
P. attenuatus has the leaves 18-20.5 mm wide, 
at midsection with 14-15 secondary veins in 
each half; syncarp 3-3.5 cm long; drupes 1 3— 
13.5 mm long; seed 3. 5-4. 5 mm long, basal; 
and the style 4- 6 mm long. 
The new epithet is the Latin word attenuatus, 
drawn out, which is given in allusion to the 
attenuate subulate leaf apex.

DIAGNOSIS OF HOLOTYPE: "Stems up to 1 m 
tall,” 6-7 mm in diameter, yellowish, smooth; 
leaves 33-37 cm long, at the middle 15-17 mm 
wide, near the base 10-11 mm wide, firm charta- 
ceous, dark green above, pale below, almost flat 
except at base, swordlike, tapering in lower l A 
to the narrower base, in upper V 3 rather sharply 
narrowed to the 7 cm subulate apex, this 5 cm 
down 1 mm wide, the secondary parallel veins 
conspicuous and at midsection 15 in each half, 
no visible tertiary cross veins, the base widened 
and amplexicaul, unarmed, but beginning at 
2-2.5 cm the margins with prickles 0.8-1 mm 
long, 2-4 mm apart, subulate, straight or arcuate, 
ascending, pale; the midrib below unarmed for 
lower 54; at midsection the margins with sub- 
ulate tipped serrae 0.2-0.3 mm long, 1.5-3 mm 
apart; on the caudate triangular apex the mar- 
gins and midrib below with prickles 0. 5-0.9 
mm long, 1-3.5 mm apart, stout subulate, arcu- 
ate, ascending; peduncle 3 cm long; syncarp 
18 mm in diameter, globose, bearing about 40 
drupes, these 11-13 mm long, 3.5-4 mm wide, 
2-3 mm thick, the body oblanceoloid, com- 
pressed, narrowed to the subulate style, 5-6- 
angled, the body 8—9 mm long; pileus 6-7 mm 
long, its base the widest part of the drupe, the 
lower part pyramidal-semiorbicular; style 3-4 
mm long, subulate, ascending arcuate; stigma 
distal, 2.5-3 mm long, linear, extending to apex, 
brown, papillose; endocarp in lower V4, obconic, 
the base obtuse, stramineous, dull, cartilaginous, 
the walls 0.2 mm wide; apical mesocarp 3.5-4 
mm long, a cavern filled with white medullary 
membranes and hairs; basal mesocarp sparse, the 
margins fibrous, the center fleshy.

DISCUSSION: P. caudatifolius is a member of 
the section Aero stigma, as is its closest relative, 
P. globosus St. John, a Malayan species with the 
leaves 11-12 mm wide, little if at all narrowed 
towards the base, at midsection the margins with 
prickles 1-1.5 mm long, 2-5 mm apart, subulate; 
drupes 14-17 mm long; and the style 3-6 mm 
long. P. caudatifolius has the leaves 15-17 mm 
wide near the middle, ligulate, narrowed below 
and near the base 10-1 1 mm wide, at midsection 
the margins with subulate-tipped serrae 0.2-0. 3 
mm long, 1.5-3 mm apart; drupes 11-13 mm 
long; and the style 3-4 mm long. 
The epithet is derived from caudatus, having 
a tail, and folium, leaf, given in reference to the 
appearance of the leaf.
