distinctly 3-co8tukte on the upper surface with short, rigid bristles on the 3 costae, but
especially on the side ones and at times another secondary nerve also bristly;
oil the lower surface the luid-costa alone boars rather long bristles; the margins
are very minutely sp-nulous-serrnlate; transverse veinlets very short and irregular.
jt/a/e spadix . . . . Female spadix erect, attached about mid;pay of the exposed part of
the leai-aheath, or at least not very near its mouth, and borne on a short
(2-3 cm. long), rather thick, densely prickly, pedicellar part; primary spathes . . . .
the fruitiug panicle is broadly ovoid, about 20 cm. in length, very dense and composed
of 4-5 very approximate partial inflorescences; the first or basal internode is also
short, cm. long, thick aod rigid; the partial iiiSoreacences have several very
approximate spikeieta; secondary and tertiary spathes annular and produced at
one side into a short concave, bracteiform, triangular, acute limb; spikelets 3-6
cm. long, the largest have 4-5 flowera on each side; their axes are rather slender
and sinnoiis; spatheis similar to the tertiary spathes; the involucrophoruoi is
callous at its axilla and has a pedicellar part which is 2-3 mm. long, angular,
narrow's towards the base, and is expanded at its upper end into a bracteiform,
concave, asymmetric, and at one side acute limb; involucre rather deeply cupular,
often asymmetrically evolute, apiculate at one side, otherwise entire ; areola of the
neuter flower depressed, distinctly marked above by a swollen crescent-shaped callus.
Fi-titUn^ perianth almost explanate; the fruit however is rendered distinctly pedicollate
by the involucre. Fruu (quite mature) elliptical-ovoid, abruptly terminated
by a stout beak, 15-16 mm. long (including the beak) and II mm. broad; the
beak alone is i mm. long and 3 mm. broad; scales arranged in 15 longitudinal
series, almost glossy, very slightly convex and very superficially or indistinctly
grooved along the centre, of a reddish brown colour and witii a narrow, lightcoloured
scarious, erosely toothed margin, the apex slightly produced, dai-k and
bluntiah. Seed globose-ovoid or slightly longer than broad, 9-5 mm. long, 8'o mm.
broad, 8 mm, thick, almost equally convex ou both sides (not veutricose on the
raphal side).

OnSEEviTIOHS.—It is related to D. anjmtifdmi, D. triehnm and D. finm, but
it is distinguishable by its small ovoid fruit, abruptly surmounted by a stout beak,
more conspicuous by far than that of any other fruit of the allied species; also
good diagnostic characteristics of D. pachjrostris are the fruit scales, very slightly
convex, and only obsoletely grooved along the centre, and the regularly globoseovoid
seed, not more ventricoae on the raphal than on the opposite side.

- tobaccccolonred, partly fugacious indumentum, and rather
powerfully armed with obliquely and irregularly seriate, loog, thinly-laminar, almost
confluent, black.sh or schistaceous, elastic, 15-28 mm. long spines; petiole rather
elongate, 2C-30 cm. long, Sattish and smooth on the upper surface,
convex and more or less prickly or even almost smooth along the centre on
the back; the margins acute and armed with straight spines, especially near its
base, where they are longer than higher up, at times as much as 3-6 cm in
length; the racliis has on the back a line of claws along the centre, solitary
at first, ternate towards the upper end, quinate on the cirrus; the salient angle on
the upper surface is very sharp and smooth; leaflets very numerous and approximate,
12-15 mm. apart, very regularly equidistant, naiTowly or linear-ensiform very
finely acuminate, sub-S-costulate; on the upper surface the side costulae have short
bristles throughout from not very far above their bases, but the mid-coata is bristly
only near the apex; on the lower surface the mid-costa alone is very minutely
and very closely ciliate; at times on the upper surface another secondary nerve'
IS more or less bristly; margins closely bristly-spinulous; the intermediate leaflets,
which are the largest, are 25-30, or at times 30-35 cm. long, 12-13 or also
16-17 mm. broad. SpaAees before the anthesis rather narrowly' fusiform ereoT
inserted not far below the mouths of their respective sheaths, almost sessile, but with
their short pedicellar pari decurrent along the sheaths, and densely prickly; the
outermost spathe ia cymbiform, very densely armed with long (up to 4 'cm )
slender, feeble and flexible, reversed, subioriate spines, and is prolonged to a beak
about as long as the body, at times furnished on its upper part with a few but
veiy long, rigid, bsir-like spiculae; the second spathe is armed with ascendent
spiculao, especially along two very obsolete carinae. Mmak jbwers ovoid, 8 mm long
The fmiün, pamek is small, erect, 10-12 cm. long, denso, formed by 4-5 very
small, very approximate branches or partial inflorescences, each of those composed of
3-5 spitelots; the spikelets are very small, 15-25 mm. long and carry 3-5
flowers in all; involucrophorum callous at its axilla, more or less pedicelliform
(1-3 mm. long), expanded at its upper end into a bracteiform, concave, asymmetrical
and at one side acute limb; involucre shallowly cupuliform, often slightly asymme
trical and more or less split on the margin; areola of the neuter flower depressed
more or less callous round the .scar. FmiUng ferianth explanate; the calyx, split in
3 pai-ts, obscurely striate-costulate or almost smooth. Frmt spherical, le'-I? mm
in diameter, terminating in a short, conical, very acute beak; scale's rhomhoidal'
slightly broader than long, arranged in 15 longitudinal series, not deeply and rather
broadly grooved along the centre; they 'are dull, of an miiform reddish or
cmnamon-brown colour, and have on almost polished, narrow, smooth (not crisped)
darter band all round; the extreme margin is very obsoletely erose; the point is
obtuse. Seed subglobular-renifom, broader than long, slightly flattened sli.htlv
