This specics, wbioli was known only through very incomplete specimenscollected
by Lobb near Bruni, has been found again by H. Hallier in Dutcb N.-W.
Borneo ot Sungei Sambas, in the homonymous Residency (No. 1086 in Qerb. Hort.
Bot. Bog.). The specimens fiom tiiin locality app&n- to have the same characteristics
lis those from W. Borneo, and seem to exclude the hypothpsis that D, microstachysrepresents
a case of nanism of D. Bystrix. These specimens reveal a small, very
slender, erect plant. The sheathed stem is 15-18 cai. in diani., the naked canes
8 mm. thick; the leaf-shratbs are split open a long way down on the ventral
sido, and are tinned, more or less distinctly, with ohliquely^seriate, rather large^
laminar spines, and smaller series of minute spieulae. Leaves never cirn'ferous in the
specimens Been by me', about 80 cm. long; petiole subterete, armed with soattere-i,
robust, 2-4 cm. long, t-traight spines; hiaflets numerous, equidistaot, linear-lanceolate;,
the largest 20-22 cm. long, 11-12 mm. broad, bristly on 3 nerves on the upper
surface, hut only on the mid-costu on the lower. Spadices axillary, very slender, about
15 cm. long on the whole; the panicle very small, ^hort, and with veiy few
branchelets, borne on a slender flattened spinnlcnis pedicellar part; the outermost
spatho is spathulate, coriaceous, bldeiitato at the apex, abnut 5 cm. long, spinous on
a dorsal central carina; the lowest iuternode of the flowering panicle is distinctly
clavate; the partial inflorescences are very small, and liave a very few, very sliort,
few-flowered spikclets, F,uit globular, 9 mm. in diam., terminating in a Vf^ry shor4
broadly-conical, acute beak; scales almost polished, i>f a cinnamon-broivii colour,
with a narrow light-coloured marginal line, neatly and narrowly grooved along the
centre; the margins very minutely erose-ciliatc. iSeed globular.

DescaiPTiON.—Slender (scandent?). Sheathed sifiW 1 - 1 ' o cm. in diameter. Leaf-sheaths
striate longitudinally, armed on the body with scattered, narrowly-himinar, 1-2 cm.
long spines, and more or ksg furnished on the ventral side of their uyper part,,
along the centre, with rigid, horizontal, blackish, needle-like spiculae, 1-1'5 cm.
long, which become slightly broader and arc, at most, 3-4 cm. long on the
margiiis of the mouths of the leaf-sheaths, whore they are ascendent or spreadingy
and never attain the extraordinary size observed in the forma iypiea, or in its
variety minor. In other respects, the var. cxulans of D. Jlystrix does not differ
from its var. minor except in its still smaller dimensions. The leaves are from
D. turbinatus'] beccari. t h e s p e c i e s o f d a e m o n o e o p s . 225
20 to 40 cm. long in the pinniferous part, the petiole is much flattened, and
shghtly prickly, or almost smooth, on the edges; the leaflets are 10-20 cm. long,
5 - 1 2 mm. broad, very closely and minutely bristly on 3 nerves beneath j the' cirrus'
ia 15-20 cm. long. Spadix l0~30 cm. long. Fruit ovoid, with a broadly-conical
acute apex, about 15 mm. long, 10 ram. broad.
HABITAT.—Dutch N.-W. Borneo.

OBSiiRvmoNS.-Distinguishable from var. minor hy the armament of the mouths
of the leaf-sheatiis, where the unusually long, erect spines, peculiar to all other
forms of D. Hystrix are wanting.

DESCEIPTIOS.—Scandent, of moderate size. Shathed stem 1-5-2-5 cm. in diam. Leaf,
sheaths strongly gibbous above, obliquely truncate at the mouth, which is fringed
with many long criniform spiculae ; the gibbosity is almost polished, and usually quite
unarmed; immediately below the gibbosity the leaf-sheaths are furnished with one
or two pairs of large, complete, membranous, almost equally broad, approximate and
decussating spiniferous collars, between which follow several other collars, more or less
complete, with a sometimes rather broad, sometimes narrow, or oven rudimentary
membranous part turned in opposite directions, but not paired. The surface of the
sheaths between the collars is glabrous and almost poHshed; the edges of the collars
are armed with several, spaced, very long and slender, flat, elastic, brown or spadiceous
spines, and between these with innumerable, blaokish, minute spiculae. Leaves rather large,
cirriferous; the petiole is biconvex, except in its lowest part, where it is flattish, or slightly
concave on its upper surface, and convex on the back; the edges are rather obtuse°and,
armed with small, short prickles, occasionally slightly reversed ; the dorsum along the
centre is smooth, or but sparingly prickly ; the rachis has its upper surface rather broad,
flattish or slightly convex in its lowest part, with an acute salient angle and flat side
faces towards the end; on the lower surface, the rachis is polished and armed along the
centre with a liue of solitaiy claws which become ternate towards the end, and on
t h e cirrus. Leaflets not very numerous, very inequidistant, and more or less distinctly
approximated into 3-4 groups, separated by vacant spaces of very unequal lengths •
the lowest group has 3-5 leaflets on each of the rachis inserted at an angle
of about 45" and spaced 5-10 mm., or at times 2-3 cm. apart- in the upper
groups the leaflets are more and more in-egularly spaced; the leaflets are ensiform
or narrowly-laneeolaw, broadest about their middle, and thence almost equally taperin^
towards both ends; theii- base is narrow and acute, aad the apex is sli-htly bristly
especially on a small indentation at the beginnini? of the tail-like tip, which
