7 0 INKALS OF THE BOTAL BOTAKIC GARDEN, CALCUTTA [¿). ANGUSTIFOLIUS.
apadicea ereot, sessile or nearly so, fusiform before flowering, almost gradually narrowing
into a beak which is about as long as the body; outer spathe eymbiform,
acutely two-keeled, rather firm, not very densely armed with flat, very thin and
elastic, very short or even 1-3 cm. long, scattered or interruptedly seriate spines ;
those on the upper part of the spathe and at the base of the beak are erect and
longer than elsewhere, and at the base shorter and spreading, and never have a
distinctly callous base; the second and following spathes unarmed, or the second
only with a few spines. Mate spadixl densely panicled, oblong-cupressiform, 17 cm.
long, with 6 or 7 very approximate partial inflorescences (in one specimen) ; their
axial parts slightly pulvernlent-furfuraceous ; spikelets very short and few flowered,
the largest (the lower ones', 15-18 mm. long with 4-5 flowers on each side; the
axis of the spikelets not very strongly aig-zag sinuous with short and very minutely
scabrid intemodes ; spathes bracteiform, amplectent, extended at one side into a broadly
triangular acute point, which readies the margin of the involucre; involucre cupular,
truncate, entire or obsoletely bi-dentate. Mai, Jbweri oblong, obtuse, 5 mm. long, 2 mm.
thick ; the calyx campannlate-urceolate, being slightly constricted at the month, superficially
3-toothed, strongly striately veined; the corolla twice as long as at the calyx.
FanaU ifodix 13 cm. long on the whole (when without the spathe«) and with 5
partial inflorescences (in one specimen) which are composed of only 6-7 spikelets;
the largest spikelets (the lowest) 4 cm. long with 4-5 flowers on each side, and
with the spaces between two flowers acutely angular and 2-4 mm. long ; spathols
bracteiform, amolectent, extended at one side into a broadly triangular acute limb,
wiiich is slightly shorter than the involucrophorum ; the latter very short (about 3 mm.
long! distinctly callous at its axilla, ohconical and expanded at its apex into
an obliquely suhcupular limb, which at one of its sides subtends the neuter flower;
involucre cupular, truncate, entire; areola of the neuter flower very distinct and
tumescent on its upper margin. F ^ l e p,mra ovate, 5 mm. long; the calyx
nrceolate-campanulate, very obsoletely 3-dcnt.culate, very strongly stnately veined;
the corolla almost twice as long as the calyx, its segments narrow lanceolate,
acute Frmting t ' M h explánate. F,mt rather small, 1..-14 mm. m diameter (not
quite mature), globose, slightly conically beaked; scales m 15 series, shm.ng,
sliehtly channeUed along the centre, of a reddish-brown colorn-, more yellowish
at the base broadly bordered with a dark chestnut-brown line and slightly produced
into an obtuse non-discolom-.d tip. Sud globular, very slightly broader than high.
HABITAT. The Malayan Peninsula. This species was described by Gnjjith from
specimoDS collected In the Province of Malacca. It has been found again at
Singapore, for I consider as belonging to ft anguitifolitu the specimen collected by
Eidby in that island at Chan Ohu Kang and distributed with the No. 46S3
(Herb. Kew.), at SeUtan (No. 6279 in Herb. Becc.) and at Lawas (No. 5123 in Herb.
Becc.). Srifflth gites the Malayan name of " U . G h i t t a " . This is also the name for
D. trichrom. Ridley gives the name of "Rotang S'pat".
OBSEKVATIOHS.—I have seen Griffith's type-spechnens of this in the Herbarium at
Kew, and on this I have chiefly baaed the description of the leaves; but for the
spadices, flowers and fruit I have made use oi Ridley's specimens.
D. thohrous^ BECOAKI. THE SPECIES OF DAEMOUOHOPS. 71
Amongst the Malayan species of the group to which it belongs, it is rather easily
distinguishable by its leaves with numerous, approximate and very regularly sot, comparatively
small, linear and narrow leaflets, which are inserted at a very wide angle or
almost horiiontally ; by the very short obconic involucrophorum supporting the
neuter flower with one of the sides of its limb, and by the small reddish-brown
or alutaceous fruits. It is, however, very closely related to D. triehnus Miq., and I
feel inclined to consider it as only a variety o£ this.
In the most typical forms of D. irichroas the scales are peculiarly spotted on
their points, while the fruits of Ridley's specimen No. 5133, the only ones I have
seen of D. angusUfolms, have the tips uniformly blackish at the margins; but this
same colouration occurs also frequently in D. irichrous.
I t is quite certain that D, carcarodon Ridley corresponds to D. angusnfoUm
Mart.; while the plant that Ridley has considered as D. angmtifolius is apparently,
at least in part, D. Sepal Becc.

DESCRIPTION.—Scandent, of moderate size. SUaihed stem 3-3 cm. in diameter.
Imf-sheaihB of the lower part of the plant and, of all non-cirriferous leaves not gibbous
above and armed with rather broad, long and .short, usually obliquely inserted, scattered,
laminar, elongate-triangular spines; the sheaths of the cirriferous leaves gibbous
above and apparently armed with smaller spines and with a petiole 30-30 cm. long;
t h e latter (in the non-cirriferous (lower) leaves is channelled above, while in the
cirriferous is flattish or slightly convex, sparsely, and not densely prickly on the upper
surface, especially near the margins, rounded beneath where armed along the dorsum
with solitary and not very strongly curved elaws which on the rachis become of the
usual kind, 2-3-nate and 5-nate on the cirrus; the margins are armed with vai-iable,
straight and sometimes robust spines; on the upper surface the rachis is smooth
throughout, obtusely convex at first, bifaced with a very acute, salient angle from
about the middle upwards. Lmjlets numerous, very regularly and closely set (10-15
mm. apart) at a very wide angle or very spreading, thinly papyraceous, green on
both surfaces 20-25 cm. long, 8-10 mm. broad, somewhat narrowed to a not very
acute base, gradually acuminatc from above the middle to a capillary tip; rather
distinctly tri-costulate on the upper surface where the mid-costa is bristly spinulous only
from the middle upwards, and the side costulae are furnished, from not very far
above the base, with rather long bristles; on the lower surface the mid-costa only is
finely and closely bristly-spinulous; the margins very finely and closely spinulous
