DESCRIPTION OF ALL SPECIMENS EXAMINED: 
Tree 7-12 m. tall, branched into an open crown, 
supported on prop roots about 1 m. long, the 
stem and roots "armed with small, sharp, up- 
turned prickles"; leaves 1.5-1.72 m. long, 4.1- 
4.2 cm. wide, coriaceous, AA-shaped in cross-sec- 
tion, ligulate, long tapering to subacute tip, and 
10 cm. back from tip only 14 mm. wide, the 
lower side somewhat glaucous, almost to the 
base the margins with subulate-tipped serrations 
1.5-2 mm. long, 2-4 mm. apart, ascending at 
45°, tipped with brownish, the midrib unarmed, 
at the middle the margins subulate-serrate, the 
teeth 0.8-1 mm. long, 2-5 mm. apart, ascending 
at 25°, brownish tipped, the midrib unarmed, 
near the tip the margins subulate-serrate, the 
teeth 0.3-1 mm. long, 0.5-2 mm. apart, the 
midrib below with similar but more remote 
teeth; peduncles leafy bracted; syncarps solitary, 
subpendent, surrounded and completely en- 
wrapped by numerous orange-yellow bracts, and 
strongly resembling an ear of corn in its husk, 
the two outer bracts with the body about 33 
X 5.5 cm., then prolonged into an acuminate, 
green tip about 20 cm. long which resembles 
the leaves, at midsection the salient, acicular 
teeth 1-1.5 mm. long; inner colored bracts boat- 
shaped, elliptic, 35 cm. long, 9.5 cm. wide, 
margins of the lower third with acicular, salient 
teeth 1-2 mm. long, 1-2 mm. apart, the middle 
unarmed, the upper third with the margins 
and midrib with teeth 0.6-0.9 mm. long, 0.5-1 
mm. apart, subulate, appressed ascending; syn- 
carps 20-22 cm. long, 7-7.5 cm. in diameter, 
cylindric, obtuse, yellow; drupes of two shapes, 
the terminal ones 14-17 mm. long, 5.5-9 mm. 
wide, 5-8 mm. thick, oblanceoloid, ending in 
the low convex pileus 1-3 mm. high; stigma 
1-2 mm. wide, on pileus but off center, lunate, 
brown, facing apex of syncarp and at right 
angles to drupe, projecting from under a car- 
tilaginous, yellowish visor, fan-shaped but 
usually with 1-3 rounded lobes; endocarp cen- 
tral, 9-10 mm. long, the sides 1—1.5 mm. thick, 
pale, hard, cartilaginous but easily broken into 
transverse fibers; lateral drupes 20-21 mm. long, 
4-5 mm. wide, 3.5— 4.5 mm. thick, the body 
oblong fusiform, the pileus 2-3 mm. high, low 
convex, its lower margin scalloped; apical mes- 
ocarp a single cavern; basal mesocarp cavernous 
in the center, fibrous on the sides. 
HOLOTYPUS: Australia, Queensland, Cape 
York Peninsula, Iron Range, common in hollows 
and gullies in rain forest, 20 m. alt., June 22, 
1948, L. /. Brass 19,293 (BRI). 
SPECIMENS EXAMINED: Australia, Queens- 
land, Cape York Peninsula, Leo Creek, Upper 
Nesbit River, frequent in a ravine in rain forest, 
420 m. alt., Aug. 16, 1948, L. ]. Brass 19,869 
(BRI). 
discussion: The closest relative is P. am- 
boinensis Warb. of the East Indies which has 
the leaf margin near the base with divergent 
spines, the midrib spiny near the base and at 
the middle; pileus apex truncate; stigma under 
a projecting entire tooth; and the endocarp 
supramedian. On the contrary, P. Zea has the 
leaf margin near the base with ascending spines, 
the midrib unarmed near base and middle; syn- 
carp concealed; pileus apex convex; stigma 
under a projecting 2- 3-lobed tooth; and the 
endocarp inframedian. 
The specific epithet is the generic name Zea 
of the cultivated corn or maize, chosen because 
of the similarity of the fruits.
