DESCBIPTION.—Scandont. Sheathed stem 20-25 mm. in diam. Leaf-sheaths flagellifer-
OU8 short thick and almost woody, gibbous above under the petiole, very obliquely
ti-uncate and open a long way down on the ventral side at the mouth, where
naked at the margins, the surface armed with horizontal or slightly defiexed, rather
strong solitary or confluent or even transversely seriate spines, which leave a deep
depression above them and are of various sizes, the largest being 2'5 cm. long,
ih-brown, paler at the apex than at the base, where flat beneath and slightly
! above. Leaf-sheath jlagella very long (in one specimen 2'5 m.), very slender,
flattened, two-edged and naked in their lowest portion, armed upwards with rather
regularly set half-whorls of moderately strong black-tipped claws. Leaves not
cirriferous, in one specimen 1'2 m, in length, including the petiole; this 25 cm.
long, narrowly channelled above, veiy convex and smooth beneath along the middle
but armed at the sides with variable (from a few mm. to 3 cm. in length)
broad-based horizontal rigid spines; rachis in its lower surface round at first, and almost
flat upwards where armed with black-tipped slightly hooked claws, these 12-20
mm. apart one from the other, with an acute salient angle above, whore smooth
and not spinulous and with the side-faces rather concave; leaflets very numerous,
equidistant, very regularly set, inserted at an angle of 45," 15—18 mm. apart, alternate
or subopposite, green, almost shining above, barely paler beneath, thinly papyraceous,
rigidnlous, linear-lanceolate or linear-ensiform; narrowed to the base and a good
deal more gradually acuminate at the summit into a very slender and acute
briatly-penicillate tip, furnished above with 3 rather distinct and smooth (not
bristly or spinulous) costae of which the mesial is the strongest; beneath, the costae
more slender than above and very densely covered with small fulvous spinules;
the entire surface minutely longitudinally striate by very fine veinlets; the margins
quite naked but distinctly thickened by a rather strong nerve and in their lower
surface very finely scabrid or shagreened when seen under a lens; transverse veinlets
especially visible on the upper surface; the largest leaflets, those of the lower
third part of the rachis, 25-26 cm. long and 13-15 mm. broad, the lower
ones a good deal narrower, those near the summit shorter and less acuminate; the
two of the terminal pair very small, free at the base.—Other parts unknown.
HABITAT.—South Borneo near Martapora on the River Dusson, Blume; N. W.
Borneo in Sarawak near Kuching, Beccari P. B. No. 1906.
OBSERVATIONS.—The above description is taken from the specimen collected by me
in Sarawak, but the species was established by Blume on a single leaf of which I
have seen a portion and which perfectly agrees with the con-eeponding portion of my
specimen; only the leaflets in Blume's specimen are a little larger (40-43 cm. in
length and 2 cm. wide) but otherwise identical.

Though seen only in a sterile condition, this Calamus appears fairly characterized
by its leaf-sheaths opened above a long way down on the ventral side; by the
deep depressions left upon them by the spines; by the petiole smooth beneath and
narrowly channelled above; by the S-costate leaflets, the costac naked above and
finely densely spinulous beneath, and chiefly by their thickened and in the lower
surface finely scabrid margins.
In the absence of the spadices it is diiScult to point out the affinities of this
species, which however resembles to a certain extent C. DiepenhortUi.

DESCRIPTION.—Scandent, slender. Sheathed stem 5-12 mm, in diam. Leaf-sheaths
flagolliferous in the adult plant when not bearing spadices, gibbous above, striate
longitudinally, sparingly armed with a few scattered straight spreading spinules,
which rest on a bulbous base, and further clothed densely in youth like the petioles;
rachises and spadicos with fulvous deciduous hairs, these resting on bulbous permanent
bases which ultimately render scabrid the entire surface of the sheaths
and other parts of the plant. Leaf-sheath flagella filiform, flattened and almost
unarmed in their basal portion, finely aculeolate upwards. Ocrea short, obliquely
truncate, densely bristly-ciliate chiefly at the margin. Leaves non-cirrifcrouc, elongate
oblong and often suddenly contracted above the middle in outline, 35-70 em
long, including the petiole; this 10-15 cm. long, deeply and broadly channelled
above, rounded beneath, where armed with scattered solitary slender claws and
furthermore, mainly near the margins, with some straight spines ; rachis densely hairyftirfuraceous,
bifaced above, rounded beneath where feebly armed from base to summit
with small solitary claws; sometimes almost smooth; leaflets thin in texture, herbaceous,
very numerous (40-50 on each side) patent, beautifully pectinate, very regularly and
closely set, linear and almost equally broad from the base to the summit, suddenly
plicate at the base and also suddenly acuminate at the summit into a setose tip,
green and subconcolorous on both surfaces, more or less distinctly S-costulate, the costae
furnished above with rigid short l ' 5 - 2 mm. long bristles; the mid-costa often
provided with a solitary, long and strong bristle at its base at the junction with the
rachis; on the upper surface occur 2 - 3 secondary slender minutely spinulous nerves
between each costa; on the under surface there are no long bristles and all the
nerves are densely covered with very fine light hairs, the primary ones more finely
