prominent, the inner ones 3-4 mm. long, 2-2.5 
mm. wide, elliptic, the outer ones 2-3 mm. 
long, 3-4 mm. wide, irregularly cordate, ele- 
vated, but more or less horizontal; endocarp 
central, 1.7-2 cm. long, bony, brown, the lateral 
walls 1-3 mm. thick; seeds 12-13 mm. long, 
broad ellipsoid; apical mesocarp with ellipsoid 
caverns mostly empty but with a few transverse 
white membranes; basal mesocarp fibrous. 
HOLOTYPUS: Maidive Islands, Haddumati 
Atoll, Hitadu Islet, common near shore, Oct. 
10, 1957, W. D. Hartman 3 (Arn., Arb.). 
DISCUSSION: P. Hartmanii is a member of 
the section Pandanus. The closest relative seems 
to be P. tectorius Soland. var. spiralis (Blanco) 
Martelli, of the Philippines. It has the carpels 
6-9, and their apices low pyramidal-convex; 
and the leaves 5 cm. wide. P. Hartmanii has the 
carpels 12-14, and their apices conic but the 
apex much depressed; and the leaves 5.7 cm. 
wide. 
This species is named for the anthropologist 
Dr. W. D. Hartman, member of the recent Yale 
University Expedition to the Indian Ocean. He 
collected all but one of the species of Pandanus 
known on the Seychelles Islands, and he col- 
lected excellent material of three new species on 
the Maidive Islands. His notes indicate the pres- 
ence of others there which were either not in 
fruit or the fruits of which were not attainable. 
Because of his excellent collections of these dif- 
ficult plants it is a pleasure to name this species 
for him.

DIAGNOSIS OF holotype: Trees 4-5 m. tall, 
about 15 cm. in diameter; trunk rather smooth; 
crown ovoid; prop roots diverging at about 40°; 
leaves 100-12,5 (-300?) cm. long, 5.2 cm. 
wide, subcoriaceous, ligulate, long attenuate, to- 
wards the base V-shaped, beyond it plane, near 
the base the margins with salient prickles 0.5— 
1 mm. long, 3-5 mm. apart, but at 15 cm. up 
from the base the prickles 5-7 mm. long, 13— 
26 mm. apart, subulate, ascending at 45°, the 
nearby midrib below with prickles 4-4.5 mm. 
long, 1 5—30 mm. apart, stout subulate, recurv-

similar to those near the base but ascending at 
25°-40°, the midrib below with prickles 4-4.5 
mm. long, 15-30 mm. apart, stout subulate, 
recurving; near the apex the margins and mid- 
rib below with prickles 0.6-1 mm. long, 3-8
