NEW OR NOTEWORTHY BORNEAN PLANTS. 153: 
hollow portion above the seed 4 to 5 mm. in diameter, the apical 
free portions convex, abruptly terminated by the somewhat oblique, 
indurated, shining style which is about 4 mm. long and wide and 
usually with 2 conspicuous teeth. 
British North Borneo, Sandakan, Ramos 1790, December, 
1920. In rather dry forests at low altitudes. A species belong- 
ing in the group with Pandanus labyrinthicus Kurz, but with fewer, 
much smaller syncarps and somewhat smaller drupes. 
Pandanus matthewsii sp. nov. § Astrostigma. 
Frutex, ramis ultimis 1.5 em. diametro; foliis numerosis, 
coriaceis, in siccitate palllidis, usque ad 1 m. longis, 1.5 cm. latis, 
tenuiter acuminatis, margine distanter serratis; syncearpils soli- 
tariis, erectis, ellipsoideis, circiter 8 cm. longis, pedunculatis, drupis 
numerosissimis, 1-locellatis, confertis, lineari-oblanceolatis, 1.5 ad 
1.8 em. longis; stigma in synearpio imbricata, plana, 2.5 ad 
3 mm. diametro, margine perspicue dentata vel crenato-dentata. 
A shrub, the ultimate branches about 1.5 cm. in diameter. 
Leaves numerous, coriaceous, pale when dry, up to 1 m. long, about 
1.5 em. wide, gradually narrowed upward to the slenderly acumin- 
ate apex, the margins rather distantly and sharply toothed, the 
midrib on the lower surface in the upper part with similar teeth, 
the teeth slender, ascending, 1 to 1.5 mm. long, the midrib pro- 
minent on the lower surface, impressed on the upper surface, the 
lateral nerves slender, 25 to 30 on each side of the midrib, densely 
arranged. Staminate inflorescences club-shaped, about 7 cm. long, 
1.6 cm. in diameter, the peduncles about 6 em. long, subtended by 
several, oblanceolate, sharply acuminate, chartaceous bracts about 
9 cm. in length. Synearps terminal, solitary, erect, ellipsoid, 
about 8 cm. long, 4.5 to 5 em. in diameter, their peduncles up to 
10 cm. long, about 6 mm. in diameter, brown, shining and long- 
itudinally sulcate when dry, the leaf-like bracts subtending the 
synearps, up to 25 cm. in length. Drupes very numerous, crowded, 
linear-oblanceolate, 1.5 to 1.8 em. long, about 2 mm. in diameter, 
1-celled, attenuate at the base, united throughout except for the 
2 mm. long stylar portion; the stigmas plane, subreniform, imbri- 
cate, 2.5 to 5 mm. in diameter, their margins distinctly and radi- 
ately dentate or crenate-dentate.

A very characteristic species belonging in the group with Pandanus 
steliger Ridl. and P. discostigma Martelli, for which Martelli has 
proposed the sectional name Astrostigma. It is most closely allied 
to the latter species, but differs radically in its longer leaves, larger 
ellipsoid synearps, and distinctly toothed stigmas. The species is 
dedicated to Mr. D. M. Matthews, formerly Conservator of Forests 
in British North Borneo.
