D. cristatus] BECCARI THE SPECIES OF DAEMONOROPS. 191 
covered by an abundant rusty-furfuraceous down, are flattened, appressed to the main 
axis, ovate in outline and divided into several gradually diminishing branchlets; of 
these the lowest carry distichally 5-6 spikelets on each side; secondary spathes very 
small, embracing, produced at one side into a small, elongate, triangular, acute point ; 
the spikelets are flat, 15-20 mm. long, 6-7 mm. broad, have (8-12) quite flatly 
bifarious, contiguous ficwers on each side, their axes strongly and closely zig-zag 
sinuous at each flexure ; spathels extended at one side into a broad, triangular point, 
which subtends the flower; involucre orbicular, shallowly cupular, entire, shorter than 
its spathel Male flowers ovoid, obtuse, 3°5 mm. long; the calyx campanulate, slightly 
3-toothed, finely striately-veined. Female spadiz has a rather diffuse, ovate panicle 
(30 cm. long in one specimen) borne by a very long (50 cm.) peduncular part; the 
outermost spathe is long, persistent, narrowly lanceolate, 25 cm. long, 2:5 cm. broad, 
smooth, except for a very few inconspicuous bristly spinules on the keels; its pedun- 
cular part is flattened, plano-convex and has sharp, almost narrowly-winged edges; 
it is 8 mm. broad at the upper end and narrows slightly towards the base, where the 
edges are armed with a few long, very slender spines; the axial parts are more or 
less fugaciously rusty-furfuraceous; the main axis is very rigid and straight, acutely 
angular and has four partial inflorescences; these are erect, 10-15 em. long, appressed 
to the main axis and have a very few (4-5) loose, spreading, long spikelets; 
Secondary spathes bracteiform with a very short annular part and . extended at 
one side into a small, triangular, finely subulate, embracing limb; the axes of 
the inflorescences are slender (not thicker than those of the spikelets) angular, 
slightly sinuous, spikelets elongate; slender, 8-10 cm. long, and with 4-6 bifarious 
ascendent flowers on each side; spathels thinly membranous with a very short tubular 
part. extended at one side into a triangular, very finely acuminate limb; involu- 
crophorum  erecto-patent, callous at its axilla, pedicelliform, angular, 2-4 mm. long, 
very obliquely extended at one side into an ovate very obtuse limb; involuere 
very shallowly concave or pateriform, very obliquely subtended by the involucro- 
phorum, produced externally into a sub-pedicelliform and callous stalk, upon which 
rests the neuter flower. Female flowers 6 mm. long; the calyx campanulate, 
broadly 3-toothed, finely  striately-veined, membranous, with a callous base; the 
corolla not quite twice as long as the calyx; the segments rather broadly triangular, 
bluntish. Fruiting pertanth obconical. Fruit, while still young, ovoid with a conic 
acute tip; scales arranged in 18 longitudinal series. 
Hasrrar.—Borneo;. on Mount Mattang near Kuching in Sarawak (P. B. 
No. 1925, male plant). Collected also by Leib, probably also in Sarawak (female 
plant in Herb. Caicutt.). Malayan name in Sarawak, ‘ Rotang Taradan." 
Recently it has been found again in Sarawak by Hewitt with male spadices in 
flower (Herb. Kew.). 
OssERVATIONS.— It is a very peculiar species, easily distinguishable by its quite 
unarmed, narrow, membranous spathes, and by the extraordinarily oblique position 
of the involucre, which is laterally prolonged into a distinct callous pedicel for the 
support of the neuter flower.
