peduncles about 25 cm. long, leafy bracted; syn- 
carps terminal, single, the largest 22 cm. long, 
13 cm. in diameter, broadly ellipsoid, obscurely 
3 - angled, the color unknown, of about 70 pha- 
langes; phalanges 5-5.5 cm. long, 4-5.1 cm. 
wide, 3. 2-4. 5 cm. thick, narrowly obpyramidal, 
4- 6-angled, when dried light brown, smooth and 
somewhat shiny, the sides gently curving or 
plane, free in upper Va , the apex broad, low con- 
vex, lateral carpel sutures mostly none, but a few 
perceptible down Va way, the central apical 
sutures 0.5-1 mm. deep, but mostly so shallow 
as to be almost imperceptible and the sutures 
merely making a tessellate pattern; carpels 7-9, 
the apices somewhat unequal as the lateral ones 
have considerable expansion on the outer side, 
but the brown colored, actual apex is subequal 
on all and is almost flat, though the central ones 
have a perceptible depressed conic elevation; 
stigmas 1.5-3 mm. long, ovate-deltoid to ellip- 
tic, horizontal, centripetal, slightly raised, below 
it the proximal suture on the carpel apex from 
very short to Vi as long as the distance to the 
inter carpellary suture; endocarp median, bony, 
whitish, that surrounding the outer seeds 2-3 
mm. thick; seeds 15—16 mm. long, 5 mm. in 
diameter, obliquely ellipsoid; upper mesocarp 
cavernous, with very stout longitudinal fibers 
and delicate, white, medullary membranes; lower 
mesocarp fibrous and fleshy, but of small extent. 
HOLOTYPUS: Australia, Queensland, Cape 
York Peninsula, Newcastle Bay, 2Vz mi. S. of 
Somerset, commonly on rocky coastline and be- 
side small freshwater streams in coastal sand 
dune area, May 13, 1948, L. J. Brass 18,792 
(BRI). 
This new species certainly belongs in the sec- 
tion Pandanus, even though the stigmas are sub- 
horizontal. None of the published species in 
that section are so similar that it would be of 
value to state the contrasting differences. 
The new epithet is geographic, indicating the 
type locality of the species.

branched into a very open crown; leaves 1.43 
m. long, 6 cm. wide near the base, coriaceous, 
ligulate, somewhat glaucous below, tapering
