Fig. 17. Pandanus Karikayo, from holotype. a, Leaf 
mm. apart, stout subulate, closely ascending; 
prickles all pale; syncarp single, terminal, broad 
ellipsoid, apparently 18 cm. long, 13 cm. in 
diameter, "bright red”; phalanges numerous, 
3. 8-4.4 cm. long, 2. 1-3.4 cm. wide, 2-2.6 cm. 
thick, obovoid-cuneate, apex slightly convex, up- 
per 14 free, sides smooth, shining, when dry 
light brown, curving or slightly channeled, 4-5- 
angled; lateral sutures none; apical central si- 
nuses 4-8 mm. deep, all narrow or a few broad 
based; carpels 10-14, rarely with a tiny, lateral, 
splintlike one also; carpel apices ascending, de- 
pressed, somewhat rounded conic, but the mar- 
ginal ones often conic, asymmetric and distinctly 
divergent, all subequal or the ones toward the 
center somewhat smaller, these about 34 as large 
as the marginal ones; stigmas 1.5-2. 5 mm. long, 
ellipsoid, short creased, prominent, raised,

base, lower side, X 1 ^ leaf middle, lower side, X 1.

Vb way to the valley bottom; endocarp central, 
bony, mahogany-colored, the lateral margins 1.5- 
2 mm. thick; seeds 10-11 mm. long, ellipsoid; 
apical mesocarp in each carpel forming a large

DISCUSSION: P. Karikayo is a member of the 
section Pandanus. Its closest relative appears to 
be P. odoratissimus L. /., of the island of Ceylon, 
which has the phalanges with the upper l A 
free; the central apical sinuses 4 mm. deep; and 
the stigmas of the outer carpels horizontal. In 
P. Karikayo the phalanges have the upper 14
