DESCRIPTION.—Very probably scaudent and apparently rather elender. Lcaf-sheatka
Leaves cin-iferous, not seen entire; petiole ; racbis in its
upper part acutely trigonous, glabrous, bifaoed and smooth above, flat beneath where
armed along the middle with solitary claws which become 3-nate upwards and regularly
half-whorled in the cirrus; leaflets numerous equidistant, rather approximate, alternate
or subopposite, tbiuly papyraceous, rather firm, green and subconcolorous on both
surfaces, elongate and narrow or linear-lanceolate, somewhat narrowed to and acuto at
t h e base, loug-acuminate into a subulate setose apex, with the mid-costa acute and
one slender nerve on each side of it, sprinkled with fulvous bristles in the upper
surface; underneath the not prominent mid-costa only more or less covered with
approximate minute hairs; transverse veinlets slender short and not very crowded;
margins with rather remote fine hairs which are more spreading towards the summit;
t h e largest leaflets, the lower oaea in the specimen of the upper part of one leaf
seen by me, 18-20 cm. long, 10-13 mm. broad, the others gradually smaller, the
uppermost narrower and about one-half smaller than the lower ones, not taking account
of a f ew diminutive ones at the base of the citrus. Male spadix Female
spaáix simply decompound (not seen entire), rather large, the axis robust and
r i g i d with many rather approximate (8-10 cm. apart) partial infloresceuces; lowest
p r i m a r y spathe . . . . , ; upper primary spathes tubular-cylindraceous, thinly
coriacGous, closely sheathing, rather short, somewhat narrowed to the base, where flaftish
on the inner side, almost polished, armed with scattered short broad-based claws,
t r u n c a t e and entire at the mouth, prolonged at one side into a short triangular point,
t h i s keeled on the back, where more densely prickly than elsewhere; partial inflorescences
arising erect from or a l i t t l e above the mouth of their own spathe and then
speedily arched-s p r e a di n g ; thosa seen by me about 25 cm. long, their axis slightly
sinuous, 3-4 mm. in diam. with 5-6 distichously alternate spikelets on each side ;
secondary spathes eloogate-infundibuliform, pergamentaceous, glabrous, finely striate,
sparingly spinulous truncate and entire at the mouth, prolonged at one side into a
short triangular point; spikelets arched, spreading, inserted just above the mouth of
their own spathe with a not conspicuoas axillary callus, 6 - 7 cm. long, the lowermost
b a r e l y longer than the extreme, with 8-10 alternately distichous rather remote flowers
on each side; the axis zig-zag sinuous; spathels glabrous, short, broadly asymmetrically
infundibuliform, narruwed a good deal to the base, entire and finely ciliolate at the
mouth and prolonged at one side into a short, broadly triangular, acute point;
i n v o k c r o p h o r um laterally adnate outside its own spathel at the base of thu one above,
two-keeled and bidentate on the side next to the axis and slightly callous at the axilla;
involucre irregularly cupular, striately veined like the spathels, obsoletely bidentate on
t h e side of the neuter flower of which the areola is depreesedly lunate and sharply
bordered. Pemale flowers 4-5 mm. long, inserted at an angle of 45°. FruiUng
peñanih subpedicelliform, the calyx hardened and callous and split down noi quito to
t h e base into 3 very broad acute lobea; the segments of the corolla as long as the
c a l y x but narrower than its lobes; staminal urceolum crowned by 6 t r i a n g u l a r teeth.
Frtiii (immature) ovoid-elliptic, small, 6 mm. broad, suddenly contracted into a long
cylindraceous beak; scales in 18 series, rather opaque, slightly convex not or very

OBSERVATIONS.—This species is founded on the upper portion of a leaf and on a
p o r t i o n of ft spadix with half-mature fruit. It must be very uncommon as it has
not been found again by any of the modern collectors. It is distinguished in the
group of C. palusiris by its narrow elongate equidistant unicostate leaflets, which have
t h e mid-costa and one slender nerve on each side of it sprinkled with fulvous bristles
above, and underneath only the mid-costa closely hairy. In the fruit-spadix and
especially in the structure of the spikelets, and in the form of spathels and involucre
i t approaches 0. palustris, and in the narrow leaflets C. viridispinus, C. simplex and
C, bubuensis.

DESCUIPTION.—Slender and apparently scandent. Sheathed stem about 12 mm. in
diam. Leaf-sJieaths rusty-fiirfuraceous, very densely armed with very unequal horizontal
or slightly deflexed solitary spines of which the larger ones laminar, often slightly
sinuous or undulate, light coloured and of a greenish hue with a dark tip, broad and
o f t e n laciniate at the base, 10-15 mm. l o n g ; with these are intermingled many others
much narrower and often setiform. Qarea rather elongate, brown, exsucoous, brittle,
hispid. Leaves cirriferous, in one specimen 55 cm. long in the pinniferous p a r t ; the
cirrus filiform, minutely clawed; petiole rather elongate (7 cm. long), flattish and
smooth above, convex beneath, armed at the sides with a few horizontal straight
s p i n e s ; rachis armed at the sides with short prickles and along the middle beneath
with claws which are solitary at first and become ternate towards the s u m m i t ; iu the
upper surface acutely bifaced f r om a littlo above the base and smooth throughout;
leaflets not numerous (31 in one leaf), very inequidistant, in-egularly grouped, but
not very approximate by their bases, all in one piano (not pointing different ways)
papyraceous, rigidulous, linear-lanceolate, very acuminate into a subulate and b r i s t lj
apex, green, slightly paler beneath, tricostulate, the mid-costa acute and the side oostae
slender, all naked on both surfaces; transverse veinlets sharp not very crowded, much
i n t e r r u p t e d ; margins smooth; the largest leaflets, those a little above the base, about
20 cm. long, 12 mm. broad ; the upper ones gradually shorter but scarcely narrower.
Male spadh simply decompound, rigid, straight, slender, erect, shorter than the leaves
(40 cm. long in one specimen), not cirriferous at its summit, with 4-5 gradually
diminishing partial inflorescences, quite unarmed; primary spathes narrowly infundibuliform,
slender and flattened at the base, membranous or papyraceous and rather
