DIAGNOSIS OF HOLOTYPE: Shrub; stem 8 mm 
in diameter at apex, yellowish, smooth; leaves 
45-47 cm long, 23-29 mm wide, soft charta- 
ceous, green above, pale green and apparently 
glaucous below, 1 -ribbed, 2-pleated, at midsec- 
tion with 17-18 parallel secondary veins in each 
side, these prominent throughout, and on the 
lower side near the tip with barely visible cross 
tertiary veins making irregular oblong meshes, 
the blade ligulate, though broadest at or beyond 
the middle, near the base 14-15 mm wide, 
abruptly contracted to a 6.5 cm caudate tip, this 
5 cm down 0.7 mm wide, the base amplexicaul, 
unarmed, the veins obscure, beginning 3 cm up 
the margins with prickles 1—1.5 mm long, 2-5 
mm apart, subulate, pale ascending at about 45°; 
the midrib unarmed for about 35 cm; at mid- 
section the margins with prickles 0.5-1 mm 
long, 4-10 mm apart, subulate, closely ascend- 
ing; on the subapical contracting region the 
margins with prickles 0.8-1. 7 mm long, 1.5- 
2.5 mm apart, divergent, and those of the midrib 
below similar but 4-7 mm apart; on the caudate 
tip the margins and midrib below with subulate 
serrulations 0. 5-0.9 mm long, 2-4 mm apart; 
pistillate inflorescence terminal, erect, bearing 
one head; peduncle 3 cm long, 3 mm in diam- 
eter, 3 -sided, bracteate; syncarp 2.7 cm long, 2.3 
cm in diameter, subglobose, bearing about 120 
drupes, these 8-10 mm long (or following 
the curve of the style 12-15 mm), 4-5 mm 
wide, 3-4 mm thick, the body oblong-obovoid, 
5 -angled, the sides striate; pileus with the base 
2 mm high, cushion-shaped, 5 -angled, finely 
striate; style 4-5 mm long, proximally ascend- 
ing at right angles, straight or twisting, slender 
subulate, firm, angled in lower half; stigma 3-4 
mm long, linear, distal, brown, running almost 
to the tip; endocarp centering in lower V 3 , and 
5-6 mm long, broadly obovoid, the walls 0.2 mm 
thick, of heavy longitudinal fibers and a thin 
connecting membrane, pale; apical mesocarp a 
broad cavern with a few white medullary mem- 
branes; basal mesocarp fleshy and with weak 
fibers. 
HOLOTYPUS: Malaya, Negri Sembilan, Gun- 
ong Angsi, eastward on ridge, 2,600 ft. alt., 24 
Nov. 1923, Mohamed Nur 11,691 (sing). 
DISCUSSION: P. mollifoliaceus is a member 
of the section Aero stigma, as is its closest rela- 
tive, P. caudatifolius St. John, of Malaya, a 
species with its leaves 15-17 mm wide, firm 
chartaceous, tapering from the middle down- 
wards and near the base only 10-11 mm wide, 
at midsection the leaf margins with subulate 
tipped serrae 0.2-0. 3 mm long, 1.5-3 mm apart; 
syncarp 18 mm in diameter, globose, bearing 
about 40 drupes; drupes with the body oblance- 
oloid, the sides smooth; pileus base pyramidal- 
semiorbicular; stigma 2.5-3 mm long; endocarp 
in lower 14, obconic; and the apical mesocarp 
longer than wide. P. mollifoliaceus has its leaves 
23-29 mm wide, soft chartaceous, tapering 
downwards and near the base 14-15 mm wide, 
at midsection the leaf margins with prickles 
0.5-1 mm long, 4-10 mm apart, subulate; syn- 
carp 2.7 cm long, 2.3 cm in diameter, subglobose, 
bearing about 120 drupes; drupes with the body 
oblong-obovoid, the sides striate; pileus base 
cushion-shaped; stigma 3-4 mm long; endocarp 
in lower V 3 , broadly obovoid; and the apical 
mesocarp wider than long. 
The new epithet is formed from the Latin 
mollis, soft; foliaceus, leafy, in reference to the 
soft texture of the leaves.
