callous bulbous base ; partial inioreaconcos ( only one seen by mo) 15 cm. long,
with 6-7 spikelols on each side; secondary spafhes rather short, infandibuliform,
covered with a tobacoo-coloai-ed scaly-turjuraceou. scurf, sharply veined, unarmed,
entire truncate and ciHolate at the month, slightly prolonged at one side into an
acute point; spikclet. arched, slender, flexuose, inserted above the mouth of their
own spathe; the lower ones, the largest, 7~S cm. long, with two assurgent (not
flatly bifarious) scries of 8-10 (lowers each; upper spikelets gradually shorter;

entire at the mouth, obsoletely apiculate at one side; involucrophornm laterally
attached at or above the base and sometimes aboat to the middle of the snathe
above its own, with a distinct asillary callus, pedicelliform, enlarged above into a
snbtrigonoas cupnlar-calyoiform truncate entire limb; involucre slightly exceeding the
involnorophorum, shallowly oupular truncate and entire, bearing at one side a
distinct cylindrnceous pedicel (1-0-2 mm, long) for the neuter flower. Female taaers
Bubcylindraoeous, 4 mm. long, 1 5 mm. thick; the calyi tubnlar, finely striately
veined, shortly and acutely S-toothed; the corolla slightly shorter than the
calyx, its segments acute; staminal urceolum crowned by 6 triangular teeth; anthers
sagittate; ovary obovoid-oblong with short stigmas. Fruiting ptrianth distinctly
pedicelliform. Fmit disposed in two assurgent series or with a secund arrangement,
globose, 13-14 cm. in diam., rounded at both ends, topped by a small conic beak;
scales in 18 series, shining, dirty straw-yellow, rather deeply channelled along the
middle, with a slightly prolonged and dark-coloured tip, the margins Snely erosely
toothed. Seed globular, very slightly compressed, rounded at both ends, 1 cm. long,
8 mm, broad, coarsely and broadly pitted when cleaned from the dry brittle crustaceous,
once Hoshy integument, witli a very narrow and deep but inconspicuous
chalazal fovea in the centre of the raphal side; albumen bony, Bubruminate by the
intrusion of the integument into the pits of the surface; embryo basal.
HAMTAT.—Java. Blame says that it grows chioSy near the banks of the rivers
in the dense forests at the foot of the volcanic mountains in the western part of
the island. Zollinger collected his specimens distributed with the No. 2302 on
Mt. Semiru, between 600-1,8U0 metres elevation.
OnssEVATIOHS.—I have seen of the authentic specimens of Blume only the
terminal part of a leaf. I have derived from Blume ray description of the
leaf-shoaths, which I have not seen, and the generalities of the leaves and of the
spadix from Zohinger's specimens.
Figure V in plate 160 of the work of Martins, representing a leaf-sheath with
a portion of the petiole and » few leaflets of C. a d s p e r n i s , does not exactly agree
with the corresponding parts of the same species in plate 14.3 of K u m p H a.
The apical porliou of a leaf accompanying the portions of spadix with female
flowers and fruit of Zollinger's No. 2302 in Herb. Boiss. whicli I have described
and photographed has the rachis armed "with solitary claws almost to the summit,
the leaflets are less bristly on the carinie and the bristles on the margins are shorter
and more adpressed than in the type-specimen. I have not seen specimens of the
varieties mentioned by

the seed, however, in this last is not at all ruminate, and the embryo is lateral,
whereas the seed of C. a d , , m m has some intrusion of the integument and a basa'
embryo. Moreover C. a d a p c n u , is distinguishable by its distinctly ciriifcrous leaves
with numerous snbcquidistant narrowly lanceolate leaflets which have the i costac
in the upper surface and the margins bristly.

DBSOHIPTIOK.—Kather slender and probably scandont. Skeatlted stem apparently
about 15 mm. in diam. The leaf upon which Blume has founded the species is
60 cm. long and bears a very small portion of its sheath, which is armed with
small straight pale spines; petiole very short ( 3-5 cm. long ) channelled above,
rounded beneath, where armed—as the first portion of the rachis—at the sides and
along the middle with relatively strong claws; in its upper part the rachis is
bifaced above, not very regularly furnished beneath along the middle with small
claws and prolonged beyond the last leaflet into a very slender filiform very short
( 2-.5 cm. long) acnleolate rudimentary flagellum; leaflets not very numerous, 12
on each side, incquidistaut, usually not remotely paired on each side of the rachis
the pairs of cue side alternating with those of the other side, 13-15 cm!
long, 1.1-18 mm. broad, narrowly oblanceolate, sub-spathulate, eoncavo-convei or
spoon-shaped at their summit, whoro very suddenly contracted into a linear acuminate
tip, this 15-20 mm. long and bristly-peuicillate at the apex, gradually narro-wed
to the base, green, concolorous and glabrous ( without bristles or spinules) on both
suiiaoes, deeply longitudinally plicate and with about seven equal slender costae •
transverse veinlets rather distinct, much interrupted; margins smooth or with a
very fe-w very adpressed spinules, the lower one bordered by a shining band
1-3 mm. broad; the two terminal leaflets not opposite. 0£ these the uppermost, the
smallest; those near the base narro-wer than, the upper ones. Other parts unknown.
HABITAT.—Collected by t'orsten in Celebes, as from Blume 1. c.
OBSERVATIONS.—Known only by the specimen of one loaf which 1 have seen; I
have not, however, observed at the mouth of its sheath the light brown bristles
mentioned by Blume. Though so imperfectly known it seems to me to belong
evidently to the group of C. symphysif^u$, and is distinct from tlie others by its
narrowly spathulate concavo-convex, many-costate plicate leaflets. I believe, however
that tho leaf upon which the spccies is founded belongs to a not fully grown
plant.
