suiall, very slender, subspiny bodies entirely hidden by the scurf, in the jowag
stage of the spadix but visible when this is removed; this structure is apparent,
though in a less degree, also in Javanese specimens of D. inehnochaetcs. The nectariform
callus at each flexure of the axis of the male spikeiets is very distinct.
A very thorough exauunation of the portions of the type of D. palcnbanictis
has allowed rue to recognize this in some specimens with male spadices, introduced
from Sumatra into the Botanic Garden of Buitenzorg and cultivated there under
the name of D. Letvisianus Grifi., " Rofcang Djernang" {vide Cat. Hort. Bog.
p. 74}. From these specimens I have derived my description of the spathes, while
that of the fruit is taken from some detached fruits received under the fame
name of D. Lcwisiams from the Leiden Herbarium; but it is impossible to be absolutely
certain that these fruits are really those of the species to which the male spadices
described above belong. I consider also as belonging to D. palemhanicus another
Daemonoropa from Paja Kombo in Sumatra—cultivated at Buitenzorg under the
number 5154—wliich has very robust male spadicts and the outer spathe armed with
distinctly laminar spines, some of these being 4 mm. broad at their base. The
leaflets often have bristles on 5 nerves above.
Another specimen also brought into the same garden from Sumatra by Teysmann
and cultivated as No. 4248 difi'ers slightly from the preceding in the outer spathe
having a shorter beak.
PLATE 6.—Dacmonorops palemhanicus Bl.
Male spadis and detached outermost spathe ; portion of a leaf-sheath and
petiole ; intermediate portion of a leaf. From a plant cultivated at'
Buitenzorg, derived from Sumatra (Herb. Beccari).
DAEMOKOROPS PALEMBANICUB var. BANGKANUS Becc.
DESCEiPTiOii.—Sheathed stem about 3 cm. in diameter, armed as in type. Leaves-
1-0 m. long in the pinniferous part; leaflets 2o cm. long, 15 mm. broad, with short
bristles on 3 nerves on the upper surface and rather regularly and closely ciliolate
on the mid,-costa on the lower. Outer spathe armed with laminar, confluent and
closely, interruptedly seriate spines, which, compared with those of the type, are
short, broad and rigid, 2-4 mm, broad at the base, 1-3 cm. long; this kind of
spine covers also a good portion of the beak, where they are more or less senate
or half-wborled, horizontal or somewhat deflexed.
HABITAT.—Introduced from Bangka into the Botanic Garden at Buitenzorg. Itis
labelled " Calamus sp. Bangka. Eakanan."
OBSERVATIONS.—It differs from the type in the short laminar spines which cover
the outer spathe.

salient smooth angle and flat side faces in its upper part above, armed underneath
upwards, as in the terminal cirrus, with 5-nate or digitate, rather slender CIEJWS.
Leaflets apparently rather numerous, equidistant, the upper ones 2-3 cm. apart^
papyraceous, dull and subconcolorous on both surfaces. The largest among thos©
seen by me, aro about 30 cm. long and 15 mm. broad, liuear-ensiform or very narrowly
linear-lanceolate, broadest a little below the middle, and thence graduully
narrowing to a rather acute base and acuminate at the apes into a filamentous
t i p ; Ihe mid-costa and ono rather distinct nerve on each side of it carrying, on
t h e upper surface, remote, shortish, blackish bristleis ; on the under surface the mid-costa
is minutely bristly from the middle upwards ; margins rather closely and spreadingly
bristly-ciliate. Male spadix erect, subsessile, broadly fusiform, apparently very variable
i n size, 12-40 cm. in length, including the not very long beak; outer spathe
obsolefely two-keeled, covered very densely with weak or flaccid, very narrowly
and very thinly laminar, black spines, which are often confluent by their bases and
sometimes so slender as to become hair-like; second spathe m t h fewer and shorter
black spines, that are more numerous along the not prominent keels; third spathe
with only one longitudinal row of small spines or almost smooth. Partial inflorescences
densely paniclcd, cupressiform, rusty-furfuraceous in every part and with many
branchlets; the latter carrying 12-13 spikeiets in all; the largest of these
the lowest, about 2 cm. long, with 5-6 flowers on each side; spathels bracteiform'
just reaching the rim of the cupular involucre with their bluntish or subacute points!
Male flowers oblong, 4-4-5 mm. long, rather obtuse ; the corolla a little more than
twice as long as the calyx. FruHvig perianth explanate. Fr-Mt, spadiz shortly
panicled, erect, r i g i d ; its internodes not tumescent at the junctures; spikeiets 2 -3
cm. long, their axis at first rusty-furfuraceous, later very slightly scabrid zig-zaosinuous,
about 3 cm. long, with 3-4 flowers on each side; spathels bractiform"
broadly triangular, acute ; mvolucrophorum short and thick, not or slightly surpassing
the apex of its spathel, broadened at the apex into an asymmetrical subcupular
limb, not or very slightly callous at its axilla; involucre cupular, short truncate
almost completely immersed in the involucrophorum ; areola of the neuter flower
depressed, slightly tumescent. Fruit spherical, 18 —20 mm. in diam. tipped by a
short beak, neatly marked by 18 longitudinal furrows; scales ia 18 longitudinal
series, narrowly and rather deeply channelled along the centre, the furrows
continuous from one scale to another, of a light, hazel-nut brown colour n-ith lighter
scarious polished margins, otherwise dull, the tip slightly produced, obtuse, bometimes
darkish. Seed globular, very slightly flattened laterally, not ventricose on the raphal
sido, 13 mm. long and a little less thick, very minutely tubercled.

HABITAT.—Siam: Koh Chang; collected by Joks. Schmidt during the Danish.
Siam Expedition, 1899—1900 (Nos. 515 and 624' in Herb. Mus. Bot. Haun.)
OBSERVATIONS.—Like almost all the other species of this group this has no veryealient
characters by which it may be easily recognized. Its principal diagnostic
characters are the following:—
Upper leaflets of the cirriferoua leaves linear-lanceolate, broadest about theirmiddle,
with remote, sbortish, blackish bristles on 3 nerves above; margins spreadingly^
