DIAGNOSIS of holotype : Roots unknown ; 
stem ”2. 5-3. 3 m tall”; leaf 1.05 m long, 4 cm 
wide % way out, 2.8 cm wide near the base, 
coriaceous, green above, paler green below, V- 
sulcate, 2 -pleated, at midsection with 40 parallel 
secondary veins in each half ; tertiary cross veins 
evident below throughout, mostly oblique, form- 
ing rhombic meshes shorter than broad; blade 
almost ligulate, widest at y 3 from apex and 
scarcely tapering before the contraction to the 
acute tip, at the point 10 cm down 36 mm wide, 
the base unarmed, pale; beginning at 2.5 cm 
up the margins with prickles 1-2 mm long, 1-4 
mm apart, the first few subulate serrae, the 
subsequent ones subsigmoid thick subulate, com- 
pressed, ascending, pale with brown tips; the 
midrib below beginning at 11 cm up with 
prickles 3-3.5 mm long, 13-24 mm apart, 
arcuate stout subulate, strongly reflexed, stra- 
mineous with dark brown tips; at midsection 
the margins with prickles 2.2-3 mm long, 7-11 
mm apart, straight or subarcuate stout subulate, 
strongly ascending, pale with brown tips ; 
throughout the central third the midrib un- 
armed; near the apex the margins and midrib 
below with arcuate subulate prickles 0.6-1. 5 
mm long, 0.5-2. 5 mm apart, strongly ascending, 
pale with dark brown tips; toward apex the 
pleats above with prickles 0.5-1. 3 mm long, 
2-11 mm apart, arcuate subulate, rigid, strongly 
ascending, pale ; pistillate inflorescence 7 cm 
long, many-bracted, cernuous, and the 3 syn- 
carps mostly concealed; peduncle 3 cm long, 
completely concealed by the crowded green 
bracts; lowest peduncular bract 3 cm long, 1.8 
cm wide, lanceolate, only the upper margins 
serrate; uppermost peduncular bract 6.5 cm 
long, 2 cm wide, oblong lanceolate, the margins 
subulate-serrate nearly throughout as is the mid- 
rib below in outer half ; bracts subtending the 
syncarps 2.5 cm long, 2.3 cm wide, elliptic, 
concave ; apical syncarp 2 cm in diameter, 
globose; lateral syncarps 1.3 cm in diameter, 
similar; drupes appearing nearly mature, but as 
they lack endocarp and seed they are immature; 
drupes unequal, those near the apex being 
nearly twice as wide and thick as the median 
and lower lateral ones; drupes (immature) 6.5- 
7 mm long, 3.3-5 mm wide, 2. 5-3. 5 mm thick, 
narrowly elliptic-obovoid, slightly compressed, 
upper y 8 free; pileus almost hemispheric, 2-2.5 
mm high, smooth, shining; stigma 1.5-2 mm 
wide, widely shallow reniform, flush, chocolate 
brown, papillose; proximal sinus wide and 
prominent, slightly exceeding the cleft of the 
stigma; fruit body with lower 1.7-2 mm fleshy; 
endocarp in lower y 3 , becoming bony, with an 
apical bristle; seed not seen; upper part 5-5.5 
mm long (apparently the upper mesocarp) 
bounded by numerous heavy, arching, longi- 
tudinal fibers. 
Staminate Plant ( Motley 1,247): Habit and 
herbage unknown ; staminate inflorescence an 
8 cm rhachis with thick, rigid bracts subtending 
the spikes; lowest bract 10.5 cm long, 4 cm 
wide, lanceolate, navicular, the margins and 
midrib below toward the apex minutely serru- 
late; uppermost bract 15 mm long; spikes 1.5- 
3 cm long, 10 cm in diameter, cylindric, dense; 
stamens clustered together, mostly in pairs ; 
column 0.8 mm long, bearing at its tip the free 
filament tips, these 0.4-0. 5 mm long; anthers 
7 mm long, linear, bearing at the tip a 0.5 mm 
subulate prolongation of the connective.

discussion: P. bracteosus is a member of the 
section Microstigma, as is its closest relative, 
P. paloensis Elmer, of Mindanao, Philippines, a 
species with bracts of the fruiting spike cadu- 
cous; stigma 0. 5-0.8 mm wide, transversely 
elliptic; leaves 24-28 mm wide, at midsection 
with 24 parallel secondary veins in each half ; at 
midsection the margins with prickles 0.8-1. 2 
mm long, 3-10 mm apart, arcuate subulate, 
compressed, ascending. P. bracteosus has the 
bracts of the peduncle and fruiting rhachis 
persistent, almost concealing the syncarps ; 
stigmas 1.5-2 mm wide, shallow reniform;
