Revision of the Genus Pandanus Stickman, Part 2 
Pandanus in Western Australia and Notes on the Section Foullioya 
Harold St. John 1 
This is the second part of a revision of the 
genus Pandanus. The previous one was printed 
in Pacific Science 14(3) : 224-241, I960. 
There have been earlier printed reports of 
Pandanus occurring in the state of Western Aus- 
tralia. These all identified the species as ones 
native to distant areas. The existing specimens 
from the region are meager, but by examining 
them in all of the principal Australian herbaria, 
it has been possible to learn enough of their 
structure to classify two of them. There are in- 
dications of a third species, but the two follow- 
ing are sufficiently known. As they appear to 
be novelties, they are here described as new 
species.

DESCRIPTION OF ALL SPECIMENS EXAMINED: 
Tree, "erect, 12-25 ft. high,” slender and with 
prop roots; leaves 1.27-1.29 m. long, 6.2 cm. 
wide near the base, 3.7-6. 1 cm. wide near the 
middle, long tapering to a slender, narrowing 
tip, the actual tip (probably about 3 cm. long 
and 2 mm. wide) is missing, and at about 10 cm. 
from the tip it is only 6 mm. wide, texture firm, 
with strong fibrous veins; the margins unarmed 
for the lower 8 cm., on the lower third the 
margins with ascending brown-tipped, subulate 
teeth 2-3 mm. long, 2-13 mm. apart, at the 
middle unarmed on one margin, but on the other 
with similar teeth, appressed and 9-17 mm. 
apart, near the apex the teeth ascending, 0.2-0.5 
mm. long, 3-7 mm. apart, midrib unarmed; 
pistillate inflorescence single and apparently ter- 
minal; peduncle 19-20.5 cm. long, 7-12 mm. 
in diameter, trigonous, with numerous leafy 
bracts up to 95 cm. long, 10-14 mm. wide, long 
tapering to a subulate tip; syncarp 10 cm. long, 
7.5 cm. in diameter, ovoid, obtusely sub trig- 
onous, drupes about 140, crowded, the upper l A 
exposed; drupes 2. 5-2.8 cm. long, 1.2-1. 3 cm. 
wide, 1 cm. thick, the base 5-10 mm. wide, the 
body narrowly obovoid, color not recorded, on 
drying the smooth epidermis exfoliating and 
exposing the numerous longitudinal fibers, apical 
concavity partly filled by a darker brown, pillow-
