46 ANÎÎALS OF THE EOYAL BOTANIC GARDEN, OALCDTTA. \D. Manii.
alteiTiato or sub-opposite, papyraceous, sub-concolovous on both surfaces, very narrowly
ensifoi'in, very gradually acuminate to a subulate and Bytiform point, and rather
suddenly narrowing in their lower pai't to an acute base; ou the upper surface
th.0 niid-costa is slender but acute, sprinkled from the middle upwards with long
light-brown bristles and accompanied, on each side, with a slender nerve which is also
equally bristly from near its base, at distances of 1-2 cm.; the under surface is
usually quite smooth or with only a few straggling bristles on the superHcial midcosta;
the margius are closely and spreadingly brisfly-spinulous ; the largest leaflets,
those a little above the base, 25-30 cm. long, 1^-15 mm. broad ; those near the
apes gradually smaller, and the ultimate ones rudimentary. Male spadix . . . .
Female spadix apparently very narrowly fusiform before flowering, erect, with a rigid
short (2-3 cm. long), unarmed (^or almost so) peduncular part; firnt or outormoat
epatbe completely enclosing the inner ones, not very deeply concavo-cynibiform,
very narrowly lanceolate, 50 cm. loug (in one specimen) and very gradually
narrowing into a long beak, thinly coriaceous, exsuccous, scaly-fur furaceous,
long persistent and marcescent, acutely 2-keeled on the dorsum, 2 cm. broad
between the two keels, and in this part ouly armed not very densely, with flat,
elastic, 1-2 cm, loug, solitary and scattered spines ; the biiak almost as
lotig as the body irad unarmed; inner .«pathes lanceolate-acuminate, very
slightly concave or almost flat, all unarmed; the axial part of the spadix
15-28 cm. long, simply decompound, cupressiform on the whole, with 4-5
erect branches or partial inflorescences; the latter glabrous, shortly and stoutly stalked,
the uppermost alone provided with a rather long peduncular part; the lower
branches, which are tbe largest, 8-10 cm. long, with 5-8 spikelets; the latter with a
rio'id, rather thick, zig-zag sinuous axis; the largest of them, the lowest, 2~i cm.
long with only 3-4 flowers on each side ; the internodes of the main axis obsoletely
angular, 3-4 cm. long, not or very slightly swollen at their bases; tbe internodes
of the partial inflorescences also obsoletely angular, 7-10 mm. long, not or very
slightly swollen at their bases ; the internodes of the spikelets (the spaces between
two flowers) 3-6 mm. long; spathels bracteiform with a very short scarious and
unilaterally apiculate or even acuminate lirab; involucrophorum pedicelliforni, 2-3
mm. long, cylindraceous or obsoletely angular, slightly callous at its axil, broadened
at tbe apex, into a short, oblique and at one side acute limb; involucre cupular,
truncate, entire or very obsoletely 3-denticulate, elightly raised above the involucrophorum;
areola of the neuter flower not very conspicuous, very slightly tumescent.
Female flowers apparently not difEering from those of D. Jenkinsianus. Fndiing perianth
persistent, not quite esplauate under the fruit, the calyx being slightly convex and
callous at the base. Fruit spherical, very shortly umbonate-mucronulate, crowned by
the small recurved stigmas, 15-18 mm. in diameter ; scales in 18 longitudinal serieS;
more deeply and broadly clianiielled along the centre of che posticoiis part than at
tbe apex, polished, brownish, very slightly darker near the margin which is very
narrowly scarious and very finely erosely toothed ; the apex obtuse and not spotted.
Seed globular, slightly flattened, not ventricose on tbe raphal side; embryo basilar,
slightly to one side.

•ATiONS.—I have seen of this two entire leaves, wanting however their
sheath, an entire spadix with nearly mature fruit and two smaller and younger
fruiting spadices. It is doubtless very closely related to D. Jenkimiams, of which
perhaps it is a geograpliical form, differing only ia the narrower and more elongated
outer spatbe, in the smooth peduncular part of the spadix, and in the fruit which
does not appear so regularly deeply longitudinally furrowed, the furrow on the
dorsum of every fruit-scule being deeper and broader on its posticous part than at
its apes The general dimensions of the plant seem smaller than those of D. JenMnsianus,
but the fruit is larger. The naked canes sent to me as those of the leafy and
fruiting specimens described above are 12-15 mm. in diameter with tbe internodes
15-20 em. long; they have a dull surtaoe and a rather distinct longitudinal costa.

DESCEiPTiON.-Hi^'h scandeiit, of moderate size or rather robust. Leaf-sheatha
armed with flat, schistaceous or blackish, long or short, more or less seriate spines'
Leaves large; petiole robust, 15-40 cm. long, lo-25 mm. broad, more or less
prickly above, especially near the margins ; leaflets very numerous, equidistant, lineareusiform,
the intermediate ones 30-60 cm. long, 15-28 mm. broad, their mid-co8ta
and one slender costulfi on each side of it bristly on the upper surface; on the
under surface naked, or more or less bristly ou the mid-costa alone ; margins
closely ciliate, spinulous. Spadices (5 and $) rather broadly- or ventricose-fusiform,
erect, subsesaile or with a very short prickly peduncular part ; outer spathes deeply
concave-cymbiform, covered with many, solitary, long, very slender and sub-bristly
spadiceous spines, which often have a paler tip; the beak as long, longer, or even
shorter than the body, unarmed except at the base ; inner spathes also deeply
concave, thinly papyraceous, the second alone more or leas spinous. Male spadix
when in flower thyrsoid-copressiform, with 5-8 partial inflorescences. Male flowers
oblong and with nearly parallel sides, 5 mm. long, obtuse. Female spadix with the
internodes of the main axis short, not swollen at the junctures. Involuerophoru7)i with
an oblique limb ; involucre shallowly cupular, entire ; areola of the neuter flower very
distinct and tumescent. Fruiiing ferianlh entirely explanate. Fruit spherical, shortly
or very shortly umbonate-mueronate, 18-20 mm. in diameter, scales broadly and rather
deeply channelled, brownish with darker intra-marginal line and an obtuse tip. Seed
irregularly globular, gibbous on the raphal side, broader than long.
