DESCRIPTION.-Seandent or standing? Sheathed stem 3-6 cm. in diam. (1-2 in.
Miquel . Leqf-sheaifis flagelliferous, thick, pale, striate, glabrous, obliquely truncate and
hairy at the nioufh, strongly armed with straight, subulate, uKuolly more or
confluent and whorled, brown-yellowish or chestnut-browu spines, of which the
about 3 cm. long, these intermingled with much smaller ones. Leaves
BubcirriferouB; petiole short, 16-22 cm. long (6-8 ia. Miquel), and about 14 mm.
thick (5 in. Miquel), rounded and strongly spinous below, especially at the margins;
the pinniferous part 1-1'3 m. long; rachis in its upper portion acutely bifaced above,
round beneath where armed with deflesed solitary or more often 3-nato piiokles of
which in this last case the mesial very long; leaflets numerous ( about 50 on each
side ) inequidistant and fascicled in groups of 5-6 (on each side of the rachis ?,
Beccari ), linear-lanceolate, acute, all similar, 16-22 or at most 24 cm. long ( 6-8 or 9
in. Miquel), and 11-14 mm. wide ( 5 - 6 lines Miquel), shining above, uui- or subtricostate
with the mid-costa acute and furnished with erecto-patent, brown, bristly
spinules, the side costae more slender and sparingly spinulous; margins spinulousserrate
; in some very adult leaves the leaflets are more rigid aud subseptemnervous;
apical leaflet, narrower than the others, a few inches long, aculeolate. LeaJ-sheaihs
Jlagella inserted near the mouth of the sheath, very long, armed with very acute
black-tipped ternate claw. Spadix {male?, Beccari), very long, with 5-6 partial
inflorescences; these bearing 5-10 alternate spikelets; primary spathes rather loosely
sheathing, with tubular, somewhat flattened, lanceolate limb; secondary spathes tubular,
short, striate; spikelets 5-5-8 cm. long; spatliels striately veined, asymmetrically
infundibuliform; involucre (spathellule, Miquel), cupular, bidentate. Flowers {male,
Beccari) rather remote, conic when in bud; calyx 3-toothed; corolla divided into 3
elongate narrow segments. (Description from Miquel, 1. c. )
HABITAT.—South. Borneo ( Miquel ).
OBSERVATIONS.—I have seen no specimens of this. I do not know auy other
Qalamui with long flagelli at the sheath.s and the leaves subciriiferous at the summit,
and at the same time with fascicled narrow sub-3-coKtato leaflets. The combined
character of the linear-lanceolate fascicled leaflets with the rachis armed beneath with
ternate deflexed spines, of which that of the centre is long, is peculiar to C. viminalis ;
but in this the leaves are not subcirriferous at their summit. The stem also is
apparently described as being erect, about as high as a man, but a full-grown
of Calamus with standing stem and at the same time with flagelliferous leafis
not yet known. For these reasons I consider C. pulcher as a doubtful
species, probably founded upon heterogeneous elements.

DESCRIPTION,—" Scandent, Leaves flagelliferous ( = cirriferous, Beccari); leaflets
few, remote, equidistant, lanceolar, five-nerved. Spines distinct, few, short and
strong; spadix decompound." ( Roxburgh 1. c. )
HABITAT.—India, in Silhet. " Hurnur-gullar, the vernacular name in Silhet, where
this species is found running over trees to a great extent; the rattan when cleaned
is about as thick as a man's finger throughout, and the joints from six to eight
inches long." (Roxburgh 1. c,)
OBSERVATIONS.—Probably under the name of C. quinquenervius lurks a very wellknown
species, not easy to recognize in the short description given by its author.
Of the species of Calamus growing in the country surrounding Silhet I know only
C. nambaricnm with ciiriferous leaves and relatively broad 5-costate equidistant leaflets;
all the other species with 5-costate leaflets having these more or less approximate
in pairs on each side of the rachis. Some forms of C. palustris ( v. ampUssimus
for instance ) have subequidistant leaflets, but I have not seen representatives of this
species collected in Silhet.

OBSERVATIONS.—Apparently a species of Daemonorops, certainly different from the
Palmijuneus vertís arigusUfolitis of Rumph., which seems to me a true Calamus
( C. Rumphii Bl. ).

Palmijuneus viminalis ambulans Rumph Herb. Amb., v, 109.
HABITAT.—Burn in the Moluccas and the not distant small islands of Kelang
and Bonoa, In Bonoa it received the name of " Ua Wuay" according to Rumph.
OBSERVATIONS.—Probably it is a species very distinct, but not recognisable in the
Tery short and vague description left by Rumph. I do not see any reason fop
considering it to be a variety of C. viminalis.
