10 cm long; stigmas mostly excentric and sub- 
oblique; leaves 10 cm wide, and at midsection 
with 87 parallel secondary veins in each half, 
and there the margins with prickles 0.6-1 mm 
long, 3-7 mm apart, subulate, weak, counter- 
sunk in the margins, appressed ascending, yel- 
lowish. P. Carrii has the drupes 7.7-7. 8 cm 
long; stigmas apical, oblique; leaves 3.6 cm 
wide, these at midsection with 49 parallel secon- 
dary veins in each half, and here the margins 
with prickles 1.7-2 mm long, 5-12 mm apart, 
subarcuate slender subulate, almost appressed 
ascending, red-tipped. 
The species is named in honor of Cedric 
Eroll Carr (1892—1936) who made a notable 
collection in New Guinea. He crossed from 
Port Moresby over the Owen Stanley Range. 
Unfortunately, when approaching the north 
coast he sickened with black-water fever, and 
died there. 
The specimen Carr 12,274 in the Arnold 
Arboretum herbarium is utterly different, an 
immature plant of the section Pandanus. There 
has been confusion in sorting and labelling it.
