This new species is named for its collector, 
Dr. F. Raymond Fosberg, of the U. S. Geological 
Survey. 
This species seems to be the one recorded 
(and doubtless misdetermined ) by J. C. Willis 
and J. S. Gardiner (1901: 104) as P. Let am 
Jones ex Fontana. That is a native of the distant 
Nicobar and Andaman Islands. It has massive 
phalanges roughly similar to those of the species 
here described, but the carpels are arranged in 
transverse, parallel lines, the stigmas are laterally 
directed, and the species belongs to a different 
section of the genus, Hombronia. They observed 
the plant, "a very large green stemmed Panda- 
nus . . . reaching a height of over 50 feet, found 
in the Hulule, Turadu, Goifurfehendu, Limbo 
Kandu, &c ( Gardiner ) , and known as Karikeo 
( Keeva in Addu Atoll 
The tentative record of P. Hornet Balf. /. in 
Baker, by Willis and Gardiner (1901: 104), 
also seems to belong here.

about 12 cm. in diameter; branches horizontal, 
then ascending; trunk gray, smooth; prop roots 
1-2 m. long, about 4 cm. in diameter, smooth, 
many of them at 6—10 dm. from ground divid- 
ing into a cluster of smaller rootlets; leaves 1.2 
m. long, 5.7 cm. wide, firm subcoriaceous, lig- 
ulate, broad M -shaped in section, long attenuate

apart, appressed, stout subulate and heavy-based; 
the midrib below with prickles 2-3 mm. long, 
13-23 mm. apart, appressed, mostly ascending;
