quarters horizontal and with two pleats that 
for the last few centimeters are subulate-serrate 
above, at midsection with 22 parallel secondary 
veins in each half, no tertiary cross veins, blade 
ligulate but contracted into a trigonous subulate 
apex which 10 cm down is 12 mm wide; near 
the base beginning at 8.5 cm the margins with 
subulate-sermlations 03-0.8 mm long, 2-3 mm 
apart, white; the midrib below unarmed to near 
the middle ; at midsection the margins and mid- 
rib below with prickles 0. 2-0.4 mm long, 13- 
4 mm apart, subulate; on the subulate apex the 
margins and midrib below with serrulations 
0.2-03 mm long, 0.5-1 mm apart, white; the 
apex short subulate, and at the point 10 cm 
down 12 mm wide; the leaves of juvenile plants 
3.63 m long, 18 cm wide; infructescence ter- 
minal on lateral branchlets; peduncle 8-14 cm 
long, 1 cm in diameter, 3 -sided; rhachis 3-5 cm 
long ; syn carps 3-4, crowded, 5-9 cm long, 
5-6.5 cm in diameter, mostly ellipsoid, but the 
smaller lower ones ellipsoid to globose, the ter- 
minal one the largest, and this one bearing 86- 
92 phalanges in mostly vertical rows, the smaller 
lower syncarps with as few as 32 phalanges; 
phalanges 27-29 mm long (including the style), 
14—20 mm wide, 11-14 mm thick, wedge- 
shaped, upper y 7 of body free (% free includ- 
ing style), on the free apex the center depressed 
conic, its sides arising from a shallow depression 
or canal within the obtuse rim, (5) -6-angled, 
the surface smooth, shiny, the sides flat; the 
(2)-3-5-(6) styles 7-9 mm long, subulate or 
acicular, irregularly grouped near the center; 
green conic style base 1-2 mm high; stigma 
5-8 mm long, linear, brown, papillose, centrip- 
etal, not running to the apex; endocarp median 
in the body, bony, brown, 10 mm long, the 
lateral walls 2 mm thick, the inner surfaces 
smooth, shining; seeds 5 mm long, ellipsoid; 
apical mesocarp of pith and longitudinal fibers ; 
basal mesocarp fibrous and fleshy.

discussion: P. pluriloculatus is a member 
of the section Acanthostyla , as is its closest rela- 
tive, P. pseudobathiei Pic. Ser., which has the 
pistillate spadix 25-35 cm long, 5-7 mm in 
diameter; syncarps 2-3, subglobose, 4-6.5 cm 
long, 33-5.5 cm in diameter; phalanges 1— 
(2-4) -celled, 26 mm long, 11-17 mm wide; 
endocarp in upper y s and 14 mm long; and 
the leaves of the lateral branchlets 1 m or 
more in length. P. pluriloculatus has the pe- 
duncle 8-14 cm long, 1 cm in diameter; syn- 
carps 3-4, mostly ellipsoid, but some lower ones 
globose, 5-9 cm long, 5-6.5 cm in diameter; 
phalanges (2)-3-5-(6) -celled, 27-29 mm 
long, 14-20 mm wide; endocarp median, 10 
mm long; and the leaves of the lateral branch- 
lets 71-83 cm long. 
The new epithet is formed from the Latin 
plus, many; loculatus, with locules or carpels, 
and is given with reference to the more numer- 
ous locules of the compound ovary.
