b o t t om of its own spathel, dunidiately infundibuliform, rather deep, somewhat narrowed
t o the base, flat, bidenfate, acutely keeiod and with the margin excavate on the side
next to the axis ; inTolucre deep subcupulav, entire, asymmetrically evolute on the Bide
of the neuter flower and subauriculiform; areola of the neuter flower conspicuous,
ovate, sharply bordered. Female jlowers very small, about 3 mm. long. Fruiting
perianih esplanate (not pedicelliform) ; the calyx split into 3 broad striately veined
lobes ; t h e segments of the corolla v e r y finely striate, acute, narrower than the lobes
of the calyx and as long as this. Fruit small, ellipsoid-ovate (when nearly ripe),
v e r y suddenly apiculate, about I cm. long, 6-5-7 mm. broad ; scales in 18 series,
pale, very convex, rather deeply channelled along the middle, with very narrow
ECarious erosely toothed margin. Seed (immature) globular, apparently with smooth
surface and a deep chalazal f o v e a ; albumen equable; embryo basal.
HABITAT.—German New Guinea: Kaiser Wilhelmsland, on the Schumann River
at 780 m. elevation, Kersting No. 437, in Herb. Berol.
OBSERVATIOSS.—This is in all respects a very distinct species from the large,
almost epetiolate leaves with very numerous, very approximate, pcctiuate, rigid,
eubhorizontal narrowly lanceolate 3-costulate leaflets, which have the 3 costae bristly^oa
b o t h surfaces and the margins adpressedly and closely spinulous; fruit small,
ellipsoid-ovoid apiculate, scales with finely erosely toothed margin.

s u r f a c e ) ; intermediate portion of u leaf (upper surface) ; the summit of a Inaf (under

DESCRIPTION.—Probably scandent and of moderate size. SUm Lmfsheaths

c i r r i f e r o u s ; petiole . . . . ; rachis of the intermediate portion glabrous,
trigonous, bifaced above with the upper salient angle obtuse and smooth, subtetragouous
near its summit where it passes into the flagellum ; in the lower surface almost polished

t h e n 3-5-nate and closely half-whorled on the cirrus; leaflets not very numerous,
not aggregate, subequidistaut, 7-10 cm. apart on each side, alternate or subopposite,
25-32 cm. long, cm. broad, lanceolate or narrowly elliptic-lanceolate,
almost equally narrowed to both ends, bristly-penicillate at the apex, papyraceous,
rigidulous, glabrous, subconcolorous on both surfaces, flat (not plano-convex) with 5
costae, of which that near the lower margin faint and naked, the other 4 spinulous
a b o v e ; underneath all nerves faint and naked; transverse veinlets rather distinct,
v e r y irregular and i n t e r r u p t e d ; margins acute, not very closely spinulous-ciliate.
Male $padix supradecompound, rather large and diffuse; primary spathes tubular, closely
sheathing, aculeolate in their upper p a r t ; partial inflorescencos panicled-pyramidate, in 2
specimens 30 cm. long, attached outside the mouth of their respective spathe, with
several branchlets (or compound spikelets) in their basal part and several simple spikelets
f r om the middle upwards; secondary spathes elongate tubular-infundibuliform, glabrous,

a triangular acute point, the lower ones, the largest, 2-2-5 cm. long; branchlets
a t t a c h e d just at the mouth of their respective spathe, the lower ones, the largest,
8 - 1 0 cm. long with 8-10 spikelets on each side; upper branchlets shorter and with
fewer spikelets; t e r t i a r y spathes infundibular, truncate, produced at one side into a
t r i a n g u l a r acuminate point; spikelets spreading or horizontal, slightly arched, flat and
comh-like (when carrying full-grown flowers), attached just at the mouth of the
spathes; the lower ones, the largest, 15-25 mm. long, brittle, with 6 - 1 5 flatly bifarious
horizontal flowers on each side; spathels bracteiform, broad with a triangular deflosed
point, this subtending its respective flower; involucre shallowly cupular, slightly bidentate

inflorescences 2-5-3'5 cm. long with a proportionate number of flowers Male flowers
oblong-cylindraceous obtuse, 4 mm. long; their calyx cupular with 3 superficial broad

t e r m i n a t i n g in a small flattened sheathed aculeolate tail-like flagellum, with a few
not very remote (10 cm. apart) partial inflorescences; primary spathes (the first not
