or oblong-lanceolate, narrowed to and rathpr acute at the base, shortly acuminate
from near the apex into an acute bristly point, opaque on tho upper surface, where
bordered along the lower margin with a broad shining band, conspicuously mealywhite
beneath, with 7-9 slender but distinct costae. of which t!ie mesial is barely
stronger than the others, all smooth on both surfaces; transverse veinlets moderately
crowded, rather distinct and much interrupted; margins acute, naked near the base,
ciliate with small spreading spinules near the summit; th(! largest leaflets, the
intermediate ones, 13-22 cm. in lengtli, cm. broad, those near the base
narrower and sbottor; tlie two of the terminal pair a trifle smaller than the others,
quite free at tije base. Male spadix Femak spadix very short and
comparatively compact, in one specimen 15 cm. long, attaclied near the mouth of
its leaf-sheath with a distinct axillary callus and transverse rima; its peduncular part
3 cm. long, compressed, flat on the inner side, slightly convex on the back, armed at
the margins with straight slender spines; primary spathes imbricate, relatively large,
broad, concavo-cymbiform, elliptic, narrowed to both ends, acJte at the Hummit, tliilny
papyraceous, exsuccous, brown, fragile, glabrous, subnitescent inside, opaque and paler
outside; the lowest very shortly tubular at the base, ventricose, almost entirely
enveloping the others, wich two faint sparingly spinulous keels on the back; the others
^4-5 smooth, longer than their respective inflorescences, the one overlapping or partially
covering that immediately above, and gradually smaller ; partial inflorescences small,
embraced by and shorter than their respective spathes, erect, ovate, rather dense, with
an acutely zig-zag sinuous axis, the largest, the lowest, 5 cm. long with 6-7 spikcleta
on each side; secondary spathes small, tubular, angular by pressure, slightly enlarged
above, finely striately veined, prolonged at the summit into an elongate entire subulately
acuminate point; spikelets erect, their axis very strongly and very suddenly zig-zag
sinuous, tho lower ones, tho largest, 12-15 mm. long with 5-6 distichous ( P ) flowers
on each side, the upper ones shorter and few-flowered; spathels (small) irregularly
infundibuliform, angular by pressure of the flowers, considerably extended at one aide
into a triangular acuminate patent strongly striately veined point; involucre horizontally
subtended by its own spathel and attached ai the base of the one above,
ii-regularly disciform, explanate; involucre calyculiform, almost explanate, witli 3 acute
strongly Toined lobes; the areola of the neuter flower depressedly sublunate. Female
Jlowers very small, 2 mm. long, ovate-conic, acute, with a flat base; the calyx striately
veined, callous at (he base, shortly 3-tootbed; the corolla scarcely longer than the
calyx, divided down almost to the base into 3 narrowly lanceolate acute segments;
stamens united by their bases and forming a not very high ring or cup, crowned
by 6 short triangular teeth; anthers broadly sa^rittate. Neiiier flowers apparently very
well developed, longer and narrower than the female ones (3 mm. long), obsoletely
trigonous, attenuate and acute at tho summit; the calyx tubular-companulate, 3-toothed,
striati='ly veined; the corolla twice as long as the calyx, divided down about to the
middltj into 3 narrowly lanceolate acuminate segments; stamens -with subulate rather
thick filaments, which are united together and to the undivided portion of the
corolla; the anthers ovate obtuse, abortive; no rudiment of an ovary (?). Fruit
unknown.

OBSERVATIONS.—his is a species very distinct by the short contracted i spadix
with large concave imbricate sjmthes, recalling those of some species of Daemonorops;
b y the leaves with grouped large many-costate lanceolate or oblong leaflets, which are
•conspicuously white beneath; and by the small spikelets with very acutely zig-zag
sinuous axis. The typc-specimen preserved at Kcw consists of the upper part of
a female spadix with rather young flowei-s and of one entire leaf; another portion
of a leaf, detached from the above specimen, is in the Calcutta Herbarium; in this
the leaflets are laiger than in the other. The Kew specimen Las 2 leaf-sheaths,
one of these bears the spadix; the other, the higher one, has a very rudimentai-y
filiform apa<lix in leogth.

DESCBIPTIOIJ.—Probably scandent. Sheathed stem about 2 cm. in diam. Leafsheaihs
not gibbous above (sometimes flagelliferous ? ) completely covered with two
kinds of spines; some of them rather large, flat, laminar, elastic, sublanceolate, 3-4
mm. broad at the base and up to 3 cm. long, scattered, ascendent, shining and
brown, while others, which are far more numerous, arc smaller, very narrow, acicular,
ascendent or spreading and never deilexed; near the mouth the spines are more
crowded, very narrow, needle-like and as much as 7-8 cm. long. Ocrea short, hidden
amongst the mass of the spines. Leaves rather robust and relatively short, not
cii-riferous; petiole robust, 1 cm. thick and rather long (20 cm.), i5at and smooth
above, rounded beneath where covered with numerous small spines of vnrious sizes
some of them not more than 5-6 mm. long, spreading or horizontal, not deflexed
and broad-based; others, those along the middle, strong, solitary and hooked; the
margins acute and also prickly; racliis in its upper portion acutely bifaced above,
and rather convex beneath, where strongly armed with scattered or irregularly
aggregate rather robust claws; leaflets large, not numerous, very inequidistant,
irregularly grouped into various fascicles of a few, with long (15-18 cm.) vacant
spaces amongst them, and a terminal fascicle of 4 ; papyraceous, rigid, longitudinally
plicate, lanceolate or elliptic-lanceolate, almost equally narrowed to both ends, acute
at the base where there is a distinct callus at its axUla and another beneath in the
hollow formed by the plicature of the limb, acuminate at the summit into a subulate
limb, conspicuously discolorous, green, glabrous and opaque above, covered beneath
with a thin crustaceous chalk-white indumentum, with 7-8 almost equal costae; these
naked on both surfaces, raised above and almost depressed beneath; the largest
leaflets 40 cm. long, o'o cm. broad ; the two of the terminal pair very shortly united
by their bases. Male spadix probably elongate (not seen entire by me), supradecompound,
with a short flattened 1 cm. broad peduncular portion which
