Obseevations.—D, Ilallienainis is apparently related to D. Sopal and especially
to D. pnciido-sepul, and Jike it, lias the leaf-sheaths costulate longitudinally and is
very similarly armed with relatively large laminar spines. Probably Hallier's
Nos. 2910 and 2129 belong to the Daemovorops mentioned by Ridley (Materials
for a Flora of the Malayan Peninsula ii, 176) as a native of Borneo, under
D. wonticolus. I have described the fi-uit of the plant from Pubu Leniukatan, which
must be considered as representing the type of the species. The Lemukatan plant
differs from those of Sarawak and Liing-gagan in the leaf-sheaths armed with
lighter (schistaceous") spines and in the leaflets larger (30-35 cm. long, 16-17 mm.
broad) than in the i-peciniens of the other above-lutntiojied localities.
The fruit of O. Jlallierianus 'from Leniukatan'' is very similar to that of D. figsus
VAR. cinnamoneits, but in this the fruit-scaks are very minutely crisped on the margins,
while they are smooth in J), uallwiantis,

Descriptios.—Apparently scandent, rather slender. iSheaihed stem 15 mm. in diam.
Leaf-sheaihs covered with a tobacco-coloured, furfuriceoua, partially deciduous indumentum,
more or leas distinctly pluri-costulate longitudinally, armed, not very densely, with
scattered or subseriate, spreading, thinly laminar, elastic, unequal, 1-2 cm. long, lightbrown
spines. Liavei of uppsr part of the plaat apparently about 1 m. long in the
pinniferous part; the petiole about 30 cm. long, 1 cm. broad, flat and smooth
on the upper and convex on the under surface of its lower portion and more or
less biconvex upwards, its margins rather sharp, and more or less irregularly armed
with spreading straight spines; the rachis in its first and intermediate portion is
aimed along the centre of the lower surface with a single series of small claws,
and has a smooth salient angle on the opposite surface. Leaflets moderately numerous,
equidistant or nearly so, 4-5 cm. apart, ensiform, or very narrowly lanceolate,
broadest about their middle, thence taperiug to a rather acute base, and gradually
acuminate towards a filamentose, sparingly bristly-spinuloua tip; their mid-costa is
acute, and has only a few spinules near the apex; of ihe side nerves one on each
side of the mid-costa is sparingly bristly-spinulous and slightly thicker than the others,
but the blade cannot be called 3-costulate; on the lower surface, the mid-costa alone
is closely and very minutely ciliate; the margins are very appressedly and rathei'
spiuulous; the intermediate leaflets are 35-40 cm. long, 2-2'5 cm. broad at

Habitat.—In the small Island of Bakau to the north of the Island of Linga
at 0". 21 N. Lat., probably collected by Teijmann (Herb. Hort. Bot. Bogor.).
Obseiivaiions.—It is apparently related to D. pseudo-sepal, with which it agrees
in its general aspect, in the equally armed costulate leaf-sheaths, and in the sniall
slightly branched spadices; but it differs in the broader leaflets, and especially in
the smaller ovoid fruit. It is also nearly allied to D. Hallienamis, but this has very
•regularly-set, approximate leaflets, and a rather large round fruit; while D. bahauemis
has sub-ill equidistant and rather remotely-set leaflets, smaller fruit and seed, and
these of a diS'erenl shape.
D. bakr-uemis is however one of those fonns of the Cymlospatha group, destitute
of prominent characteristics, which approach to more than one species, but do not
exactly agree with any one oi them, therefore, though reluctantly, we are obliged to
•distinguish it with a distinct name.

Descriptio.v.-Sheathed stem 2-2-5 cm. iu diam. Leaf-sheaths, apparently when
yoiing, conspicuously mottled with white and green (the light-coloured patches
i-esulting from a thin coating of white scurf), almost horizontally truncate at the
mouth, where they are briefly edged by a rudimentary, membranous, dry, brittle,
deciduous ocrea, and are almost without spines; the leaf-sheaths are also conspicuously
pluri-costulate longitudinally, smooth on the costae, otherwise armed with scattered
broadly laminar, elongate-triangular, brown, very acuminate, very thin and elastic,'
spines, usually 1-3 cm. long, but at times much less. Loaves 0 - 9 -M m. long in the
pinniferous part, prolonged into a loog, very closely and very minutely clawed
cirrus; the petiole is flattened, biconvex, 15-18 cm. long, 8-10 mm. broad, sparingly
