2-6 mm. apart, ascending at 45°, subulate, 
stramineous but brown-tipped, the basal mid- 
rib unarmed; the margins in the midsection 
with teeth 0.5-1 mm. long, 1-2.5 mm. apart, 
subulate, ascending, closely appressed, of the 
same color, the nearby midrib with similar teeth 
only 0.3-0. 5 mm. long, 2.5-8 mm. apart; near 
the apex the margins with subulate-tipped serra- 
tions 0.3-0 .4 mm. long, 1-2 mm. apart, ascend- 
ing, of the same color, the adjacent midrib be- 
low with similar teeth 2-8 mm. apart; syncarps 
about 13 X 11 cm., solitary, pendent, ovoid- 
globose; phalanges numerous, 4.3-4.5 cm. long, 
33-4.2 cm. wide, 2.4-33 cm. thick (but in a 
doubled one 4.1 X 5.7 X 33 cm.), pyriform, 
laterally compressed, the truncate apex about 
l /z as broad as the phalange, 4-6-angled, lateral 
sutures none, the sides smooth, curved surfaces, 
when dried light brown, somewhat shiny, upper 
3/5 free; carpels 12-16 (28 in a double), 
crowded in a flat central apex, the tips 4.5-7 
mm. long, narrowly compressed pyramidal, the 
marginal ones arcuate, incurving, sharply angled, 
the inner ones symmetric and mostly narrower, 
the central apical sinuses 4-6 mm. deep; stigmas 
1-1.5 mm. long, centripetal, oval to suboricular, 
creased, black, apical or subapical, flush on the 
inner side of the conical apex below an over- 
hanging, cartilaginous, pale, cochleare tip; below 
the stigma the proximal crease on the carpel is 
prominent and with pale liplike edges; endocarp 
median, bony, extensive, mahogany brown, the 
lateral margins 3-5 mm. thick; seeds 12-14 mm. 
long, 3-5 mm. in diameter, ellipsoid; apical 
mesocarp with numerous narrow caverns trav- 
ersed by strong fibers and pale medullary parti- 
tions; basal mesocarp fibrous and fleshy. 
HOLOTYPUS: Australia, Queensland, Cape 
York Peninsula, Brown’s Creek, Pascoe River, 
frequent in brushy forest on islands in flood 
bed of creek, 60 m. alt., July 13, 1948, L. /. 
Brass 19 M0 (BRISBANE). 
DISCUSSION : P. cochleatus is a member of the 
section Australibrassia which is a segregate from 
the section Vinsonia. Its closest relative is the 
Australian P. conicus St. John, from which it 
differs by having the prop roots absent; leaves 
1-1.2 m. long, 3.2 cm. wide, at midsection the 
marginal teeth 1-2.5 mm. apart; syncarp 13 X 
11 cm., ovoid-globose; phalanges 43-4.5 cm. 
long, the upper 3/5 free; stigmas apical or sub- 
apical, flush on proximal side of carpel apex, 
under an overhanging cartilaginous cochleate 
tip; and the endocarp median. On the other 
hand, P. conicus has prop roots 40-50 cm. long, 
slender, numerous; leaves 3-3.2 m. long, 4.5 cm. 
wide, at midsection the marginal teeth 3-10 
mm. apart; syncarp 24 X 16 cm., elliptic-ovoid; 
phalanges 6-6.2 cm. long, the upper Yz free; 
stigmas apical and overlapping on both proximal 
and distal sides of carpel apex; and the endocarp 
supramedian. 
The new epithet is from the Latin cochlea, 
sea shell or snail shell, an allusion to the shell- 
like carpel apex that overhangs the stigma.
