Frutex erectus, circiter 2 m. altus; foliis 2 ad 2.5 m. longis, 
3.5 ad 4 cm. latis, coriaceis, abrupte acuminatis, margine denti- 
culatis ; synearpiis 4 vel 5, confertis, obovoideis, 8 ad 10 cm. longis, 
7 ad, 9) om. Manic: drupis numerosissimis, confertis, 1- locellatis, 
cireiter 3 em. longis, usque ad 5 mm. diametro, apice pyramidatis, 
scaberuhs, brunneis, attenuatis; stylis rectis vel curvatis, rigidis, 
spiniformis, circiter 1 cm. longis. 
An erect shrub about 2m. high. . Leaves 2 to 2.5 m. long, 3.5 
to 4 cm. wide, coriaceous, rather pale when dry and somewhat 
glaucous beneath, margins distantly and minutely toothed, the 
midrib beneath in the upper half sparingly denticulate, the two 
lateral nerves on the upper surface sparingly denticulate for the 
upper 20 to 30 em., apex shghtly acuminate, the acumen rigid, 
slender, 2 to 3 cm. long. Syncarps usually 5, obovoid, crowded at 
the apex of the peduncle, 8 to 10 cm. long, 7 to 9 cm. in diameter. 
Drupes very numerous, crowded, about 3 cm. long, up to 5 mm. in 
diameter, base attenuate, narrowed into the rigid, very sharp, 
straight or curved style, the apical part 10 to 12 em. long, brown 
when dry, minutely scabrid. Endocarp in the lower one-half, about 
1 cm. long, base acute, apex rounded. The hollow space in the 
mesocarp about 8 mm. long, less than 5 mm. wide. 
British North Borneo, Kudat, Castro 976, November 20, 1920. 
In the hills on the Pitas Estate, altitude about 25 m. This species 
must be closely allied to Pandanus gibbsianus Martelli, which, how- 
ever, according to Miss Gibbs, quoted by Martelli, has leaves 10 to 
12 cm. wide, while in the present species they do not exceed 4 cm. 
in width. The obovoid, rather than oblong or globose synearps, 
are rather smaller than in Martelli’s species, but there are apparent- 
ly but slight differences in the drupes. 
Pandanus pachyphyllus sp. nov. § Acrostigma. 
Caulis 3 em. diametro, 10 ad 15 em.. alta, simplex; folus 
numerosis, confertis, crasse coriacels, circiter 3.2 m. longis, 5 ad 6 
cm. latis, tenuiter acuminatis, margine acute dentatis, dentibus 
superioribus parvis confertis, inferioribus majoribus distantibus 
patulis; synearpiis erectis, solitariis, globosis, 10 cm. diametro, 
drupis numerosissimis, confertis, 1-locellatis, circiter 4 cm. longis, 
5 mm. diametro, in dimidio inferiore connatis, in dimidio libero 
lanceolatis perspicue 5-carinatis acuminatis brunneis 4 ad 5 mm. 
diametro, rectis vel leviter curvatis, stigmate spiniforme. 
Stemless or nearly stemless, the leaf-bearing portions of the 
stems above the surface of the ground 10 to 15 m. high, about 3 
em. in diameter, unbranched. Leaves numerous, crowded, thickly 
coriaceous, about 3.2 m. long, 5 to 6 cm. wide, narrowed upward to 
the slenderly acuminate apex, pale when dry, somewhat shining, 
the midrib impressed on the wpper surface, prominent on the lower 
surface, the lower part furnished with widely scattered, rather stout
