140 ASKALS OP THE BOYAL BOTANLC GAHDEN-, CALOURRA. [p. elongatuspapyraceous,
very narrowly lanceolate or lanceolatc-ensiform, broadest
not very far above the base, narrowing thence shortly towards it, and upward
gradually acuciunate to a finely subulate and, at the sides, bristly-spinulous tip;
on the upper surface the mid-costa is slender and sharp, spinulous only near the
upper end, and accompanied on each side by a slender secondary nerve (^stronger
however than several other nerves of the same kind) furnished with several short
blackish bristles; underneath, the mid-costa alone is mora or less minutely bristlyspinulous;
transverse veinlets very sharp oa both surfaces, numerous and much
interrupted; margins finely and closely spinulous; the largest leaflets are those a
little above ' the base which are 25-28 cm. long, 18-30 mm. broad in Motley's-
Bornean specimens, and as much as 35-40 cm. loag and 25 mm. broad in the
cultivated plants; the leaflets towards the upper end are gmdually shorter and moro
spaced. Spadices, male and female, very similar, before flowering very narrowly
cylindrical and elongate, slightly arched and nodding; primary spathes coriaceous, at
first tubular, each protruding considerably beyond that immediately below, obliquely
truncate at the mouth; after the anthesis the outermost spathe spreads out and is
narrowly elliptical or elliptical-lanceolate or at tim.e3 sabspathulate or spoon-shaped,
gradually diminishing towards the base to a more or less elongate, sparsely prickly
and flattened pedicellar part; it also narrows slightly above to a shortly bidentate
apex, is reddish brown and polished inside and more or less rusty-fni-furaceous
externally, where it is entirely covered with small solitary, more rarely digitate,,
scattered, deflexed, brown spines, which rest on a lighter and sab-balbaus base;
inner spathes deciduous, broadly linear, briefly bi-deatate at the upper end, more or
less striate longitudinally; the second rather" densely, the others sparingly
prickly towards the apex, the ultimate spathes unarmed. Male spadiz 40-75 cm.
long; the flowering panicle strict, very slenderly fastigiate and with 6-8
partial inflorescences, more or less persistently rusty-farfuraceous in every part;
its main axis is cylindraceous or obsoletely ^angular, as slender as a pack-thread,
usually marked by numerous small depressions; partial inflorescenced about 10 cm.
long, cupressiform and appressed to the main axis, (the ultimate smaller), formed by
10-12 branchlets, each bearing 8 - 1 0 gradually diminishing fastigiate spikelet's; secondaiy
and tertiary spathes small, very shortly embracing, produced at one side into a
short bracteiform, triangular, acute point; spikelets small, fiUform, the lower (largest)
9 - 1 0 mm. long, and with 8-10 unilaterally set flowers; their axes irregularly
sinuous, and strongly indented at the insertions of the flowars which are often in pairs:
spathes very small, produced at one side into a triangular, not very acute point;
involucre very small, with the limb reduced to a very narrow annular rim round the
circular scar. Male flowers very small, oblong, 3-5 mm. long; the calyx very
shallowly cupular, with 8 small acute teeth; the corolla [several times longer than
the calyx. Female spadix about as long as the male or rather shorter; the peduncular
part sometimes 20 cm. long, usually less, flattened, more or less armed all round with
id, solitary or confluent, and subdigitatc, straight, rather short spines: it slightly
I above, where it gradually passes into the first spathe; the flowering panicle
is oblong, formed by 6 - 7 partial inflorescences; the main axis is straiglit, has the
lowest internodes short, terete, and about 5 mm. in diam. while the other internodes.
are more or less angular; the secondary and tertiary spathes are very small, acarious,.

annnlar-amplectent, briefly produced at one side to a triangular point; the partial
inflorescences have a distinct axillary callus, are triangular in outline, about 15 cm.
long and have 6-7 bifariously and regularly alternate, spreading, gradually diminishing
spikelets on each side; the axis of the inflorescences is straight, very
acutely 3-4-gonou8 with very narrowly winged angles; the lower spikelets (the
largest) are 6 - 7 cm. long, and have 8-10 bifarious flowers on each side, their axis
very acutely angular and zig-zag sinuous; spathels acarious, very short, annularamplectenfc,
produced at one side into a triangular, spreading, acute point; involucropborum
distinctly pedicelliform, 2-4 mm. long, angular, slightly narrowing towards
the base, very spreading or horizontal when bearing the fruit; it has a distinct
axillary callus, is truncate at the upper end, and there produced at one side into a
triangular acute point; involucre slightly raised above the involucrophorum, its limb
represented by a very narrow annular rim round the flat orbicular surface upon
which the flower rests ; areola of the neuter flower rather small, concave, niche-like not
callous. Female flowers small, 4 mm. long, the calyx very shallowly cupular, with
3 very superficial acute teeth, the corolla 4 times as long as the calyx, callous at
its base, parted down past the middle into 3 broadly triangular, acute, sharply
striately veined segments. Fruiting perianth very broadly obconical, and very shortly
pedicelliform. Fruit small, globular-ovoid, 9 mm. in diam., shortly and suddenly but
distinctly conically beaked, 12-la mm. long (including the beak and perianth);
scales aiTanged in 13-15 longitudinal series, glossy, narrowly grooved along the
centre, rhomboid, with a very slightly produced obtuse point, greenisii-yellowish, with
a lighter, scarious, erosely toothed edge. Seed globular, 7 ram. in diameter; albumen
ruminate, embryo basal.
HABITAT.—South Borneo. It was based by Blume upon the specimens collected
in the interior' of the Province of Banjarmassing by Eenrici found again at
Banjarmassing by Motley (Fo. 672 and No. 1170 in Herb. Kew.). Motley says that
it produces a strong but coarse Rotang.
Apparently belonging to D. elongatus is a Daemonoro^s collected by Ridley in
February 1896 in Pulo Pinang at Balik Pulau (No. 7905 in Herb. Kew. et Calcutt.).
Ridley gives other localities for D. elongatus, but 1 have not seen his specimens
except No. 7905. '
OB8ERVATioss.-Among8t the species of the group of D. Uystrix, which have
the leaf-sheatbs armed at the mouth with very long, erect, spines, D. elongatus is
easily distinguishable by its leaves with inequidistant leaflets, and by its small
globular-ovoid, beaked fruit. '
I have based my description mainly on the specimens cultivated at
comparing these with Blume's authentic ones; in these some of the
much as 50 cm. long and 28 mm. broad. Motley's specimen No. 1170 is
than those of Blume; the leaf-sheaths are only 15-1» mm. in diam. and the
leaflets are but 25-28 cm. in length, and 18-20 mm. in width; the spadix
is 35 cm. long, including the pedicellar part. Motley's No. 672 has still smaller
