of the surface nrmecl "witli subulate, straight, scattered, horizontal or slightly deflexed
spiaes which arise from a swollen base. Ltaf-tlwaih Jlagellu filiform, clawed upwards,
strictly sheathed ID their basal portion with a flattened spatlie which is spinous at the
margins and densely bristly at tlie mouth. Ocrea rather short, liguliform, densely bristlyhispid,
decurrent on the borders of the leaf-sheaths and at the base of the petiole.
Leaves about 1 m. in length, nut cirriferous; petiole short (4-7 cm. long), naked or
eparsely aculeolate at the sides, convex, polished and unarmed beneath, slightly concave
or faintly and broadly channelled above near the base, flattish upwards, rachis channelled
above ia its lirst portion, bifacod upwards, rounded beneath, where armed near
the base at the sides and throughout along tho middle with small solitary or geminate
claws; leaflets numerous, inequidistant or approximats into a few groups of many,
where they are equidistant and about ló mm. apart one from the other, the various
groups being separated by vacant spaces of 4-5 cm. in length, narrowly lanceolate,
almost equally attenuated to boih ends, gradually acuminate intu a bristly-peniciilate
tip, thinly chartaceous, rigidulous, almost concoloroas on both surfaces, 10-lS cm. long
1 cm. broad, sub-S-costate above, with the mid-costa acute and one weaker nerve
on each side of it, all three furnished with few, relatively strong, almost black setae ;
beneath all nerves faint and naked; transverse vcinlets fine, not very crowded; margins
with few and long cilia. Male spadiz Female spadix rigid, short, siiuply
decompound; primary spathes tubular, slightly enlarged above, chartaceous, aculeolate
on the back, more or less lengthened out at the summit into a lanceolate limb,
bnslly-bearded at the margins; partial iuflorescences stiff, erect, the largest seen bv
me about 20 cm. long, furnished with 3 - t spikelets on each side and terminated
by a rigid tail-like appendix; secondary spathes elongate-infundibuliform, unarmed,
finely striately veined, entire, obliquely truncate and naked at the mouth, prolonged at
one side into a triangular erect acute point; spikelets inserted just at the mouth of
their own spathe and arising erect from it, then spreading flexaose, rigid, cylindraceous,
rather thick, terminated by a short, tail-like, rigid, 1 cm. long appendix; spathelsinfundibuliform,
finely furfuraceous, striately veined, truncate and naked at the mouth,
where produced at one side into a short, acute, patent point; involucrophorum cupular,
hollowed out into the base of the spathel which is above its own and with a very
short limb; involucre deeply cupular, truncate, emarginate on the aide next to the axis;
areola of the sterile flower distinct, depressedly lunate. Female flotvers relatively large
(5 mm.). Fruiting perianth not pedicelliform, but with the calyx narrowed and callous
at the base and enclosed in the involucre, divided down beyond tho n.iddle into
3 ovate, acute lobes ; corolla with the segments narrow and not longer than tho calyx.
Fruit (mature) obovate, about 18 mm. long and 11-12 mm. in diam., conically
beaked; scales in 18 series, dark-yellowisli, convex, slightly channelled along the
middle with a rather broad, very dai'k intramarginal lino and lighter, erosely toothed
tip and margins. Seed ii-regularly subsphasric, 9 mm. long, 6 mm. thick, with a
deep circular chalazal fovea on the raphal side, convex and uneven on the back •
albumen equable; embryo basal. '
HABITAT.—The native country of this species is said by Blume and Miquel tobe
New Guinea, where it was probably gathered by Zippel on the southern coast of
that Island; but Blume on a label to some fruits of this species in the Leyden
Herbarium has written: "Timor; Zippel;" Miquel (Fl. Ind. Bat. iii, 101) gives-

also the localities of Makassar and Bouton in Celebes for C. harlaius, but I can
hardly believe such a thing possible, as I do not know any species of Calamus
inhabiting two such remote regions.
OBSERVATIONS.—A very distinct species not closely related to any other known to
me, My description is based upon one of the type-specimens of Blume preserved at
Leydcn. Amongst the Papuan species it is distinguished by the spinous leaf-sheaths
gradually passing into the petiole and densely covered near the mouth with brown
erect rigid bristles; by the leaves with a short petiole and numerous inequidistant
narrowly lanceolate subtricostulate leaflets, their 3 nerves bristly above, naked beneath;
by the rigid short spadix with spathes which are densely bristly bearded at their
mouth.

DKSCEIPTION.—Scandent, slender. Sheaihed stem 12-15 mm. in diam. Lcef-sheaihi
flagelliferous, slightly gibbous or pouched above, with an obtuse slightly raised costa
which runs downwards lengthwise from the base of the flagellum, and rather densely
armed with small, short (o mm. long at most), flat, delicate or almost bristly,
deflexed, scattered, and occasionally bi-trifid spines. Leaf-sheath Jlagelld slender, filiform,
densely armed with small, slender, solitary, geminate or temate claws. Ocrea uncommonly
large, completely enfolding or sheathing the younger part of the stem, 15-18
<5m. long, very thinly membranous, and exsuccous, later lacerated and finely
fibrous and ultimately destroyed. Leaves short (about 60 cm. long), not cirriferous,
with the petiole almost obsolete; rachis flat in its first portion and bifaced
upwards above, rounded and unarmed beneath near the base and armed upwards
along the middle with solitary rather slender claws; leaflets very numerous, equidistant,
closely inserted at a rather acute angle, thinly papyraceous but rigidulous, dull on both
surfaces, slightly paler beneath, liaear-ensiform, subulately acuminate at the summit
somewhat narrowed to the base, (i-costulate, or with an acute mid-costa and
one distinct secondary nerve on each side of it, the 3 nerves furnished above with
many dark and rather long bristles ; beneath, all nerves faint and with a few
bristles confined to the central one ; margins very minutely and appressedJy spinulous
except at the point, where the spinules are longer and spreading; i;he largest
leaflets, those of the lower third-part of the rachis, 20 cm. long and 10-12 mm.
broad ; the uppermost suddenly a good deal shorter and less acuminate, the two
of the terminal pair small and froo at the base; transverse veinlets not very regular,
much interrupted and very sharp. Male and female spadices very much the same,
elongati^-flagelliform; primary spathes very loug-tnbular and strictly sheathing, decayed
and afterwards lacerated and fibrous at the mouth, fugaciously rusty-furfuraceoue,
rather densely armed with many very small solitary short black-tipped claws which
have a broad and light-coloured base; lowest primary spathe somewhat compressed,
not very acute at the edges, flattish and unarmed on the inner side, densely armed
•with the usual small slender claws on the back; the upper primary apathe.
