both leaf surfaces a reticulate appearance, the 
blade ligulate, rather sharply contracted to a 29 
cm subulate, caudate, trigonous apex, this at 10 
cm down from the tip 1 mm wide, the base not 
preserved, near the base the margins with thorns 
5-7 mm long, 11-24 mm apart, deltoid, subu- 
late, flat, slightly arcuate ascending, pale except 
for tiny blackish tips; the midrib below with 
heavy based, terete spines 5-6 mm long, 12-30 
mm apart, subulate, arcuate, reflexed, black; at 
lower third the margins with spines 4-5.5 mm 
long, 13—29 mm apart, heavy subulate, arcuate, 
ascending, pale throughout or with minute 
blackish tips; the midrib with spines 4 mm 
long, 4.5-6 cm apart, flat, heavy subulate, arcu- 
ate, strongly reflexed; on the contracting area 
near the tip the margins with prickles 1.2-2 
mm long, 1-4 mm apart, subulate-tipped ser- 
rae, arcuate; the midrib below narrow, sharp, 
salient, bearing similar prickles; on the caudate 
apex the margins and midrib below with ser- 
rulations 0.2— 0.4 mm long, 1—4 mm apart; pis- 
tillate inflorescence "about 30 cm. long,” pe- 
duncle about 10 mm in diameter, 3-sided, leafy 
bracted, apparently bearing a single syncarp, 
this apparently about 15 cm long and 10 or 11 
cm in diameter, ellipsoid (an estimate based 
upon a part of the core, two slabs of drupes, 
and many separate ones) ; drupes numerous 34- 
36 mm long (or following the curve of the 
style 37-41 mm), 8-12 mm wide, 7-12 mm 
thick, narrowly oblanceoloid, a little com- 
pressed, 5-7-angled, the body 30-32 mm long, 
narrowly ellipsoid or fusiform, the sides gently 
curved or plane; pileus 9-12 mm long, the base 
pyramidal-semiorbicular, smooth; style 3-5 mm 
long, bony, rigid, shining, flattened, proximally 
curved, the base broad oblong, the upper part 
sharply bifid with subulate tips but the outer 
sides with broad, more or less undulate, ex- 
panded margins; stigma 3-4 mm long, broad 
ovoid, bifid, running to the apices, brown, papil- 
lose; endocarp submedian, bony, dark brown, 
the lateral walls 1 mm thick, the inner surface 
shining, with a narrow conical projection run- 
ning upward into the beak; seed 15 mm long, 
5 mm in diameter, ellipsoid, obtuse; apical 
mesocarp cavernous, but with fibers and mem- 
branes; basal mesocarp fibrous up the margins, 
fleshy within.

DISCUSSION: P. distentus is a member of the 
section Rykia, as is its closest relative, the Ma- 
layan species P. longicaudatus Holttum & St. 
John, a species with the drupes 41-44 mm 
long, the lateral ones with styles 4-8 mm long, , 
bifurcate, the forks subulate; endocarp walls 
1.5-2 mm thick; leaves 4.7-6 cm wide, the 
caudate apex 15-22 cm long, secondary nerves . 
48 in each half, and near the base the margins , 
with thorns 3-5 mm long, 6-14 mm apart. P. 
distentus has the drupes 37-41 mm long, the 
styles sharply bifid, but the lobes with undulate, 
expanded outer margins; endocarp walls 1 mm i 
thick; leaves 9 cm wide, the caudate apex 29 1 
cm long, the secondary nerves 61 in each half, 
and near the base the margins with thorns 5-7 i; 
mm long, 1 1-24 mm apart. 
The new epithet is the Latin participle dis- 
tentus, distended, and is given in reference to ; 
the lateral extensions of the style forks.
