Description.—Not scandent. Stem the height of a man.  Leaf-sheaths densely 
armed with slender spines. Female spadiz simply decompound with many partia 
inflorescences, which bear many spikelets; these 2-2°5 cm. long with two collateral 
assurgent series of 6 flowers each; involucrum distinctly cupular. Fruit very closely 
packed in the spikelets, ovate, distinctly conically beaked, 15-17 mm, long, 1 cm. 
broad; scales numerous. Seed flattened, enveloped by an acid fleshy integument and 
with a distinct chalazal fovea. ( Descript. from that of Rumph, and from his plate.) 
Hasitat.—Bouton in Celebes. 
OssERvaTIONS.— Blume had reduced Rumph’s **Rottang Assam" to C. barbatus; 
but it seems to me a quite distinct species because of its very short spikelets with 
very closely packed fruits.

DzscRrPTION.— Apparently erect or stemless or tufted, of rather small dimensions. 
Leaf-sheaths not tubular, open on the ventral side and gradually passing into the 
petiole, powerfully armed with confluent or shortly transversely seriate, horizontal, 
laminar, subulate, 2-3 cm. long spines; petiole elongate, 8 mm. broad, deeply 
channelled above, rounded beneath, where smooth along the middle, armed at the 
Margins with rather strong, straight, subulate, at the base callous, 3-4 cm. long 
spines; rachis in its first portion armed beneath along the middle with long, solitary, 
remote, horizontal, straight, broad-based spines, upwards acutely bifaced above and 
naked beneath. Leaves rather large, non-cirriferous, pari-pinnate ; leaflets numerous, 
equidistant, the lower ones closely alternate, the upper ones usually opposite and 2-2°5 
cm. apart, papyraceous, linear-ensiform, slightly narrowed to and suddenly plicate 
at the base, where rusty-furfuraceous beneath in the plicature, gradually acuminate 
to a long and subulate bristly tip, light green even when dry, opaque, slightly 
paler and subglaucescent beneath, where the nerves are slender and quite naked, with 
3 acute rather closely spinulous costae above; transverse veinlets minute, inconspicuous ; 
margins very minutely adpressedly and remotely spinulous from the middle upwards; 
the largest leaflets, the lower ones, 30-40 cm. long, 10-15 mm. broad: the upper, 
ones suddenly decreasing in length, less acuminate and some of them almost obtuse: 
the two of the terminal pair the smallest, very narrow, free at tbe base. Male 
spadiz . . . . . Female spadiz apparently with a rigid, erect, slender, straight, unarmed, 
rusty-furfuraceous axis and with a few distant superposed inflorescences; primary 
spathes elongate-cylindraceous, closely sheathing, papyraceous, unarmed, prolonged at 
the summit into a lanceolate ultimately fibrous lacerate limb; partial inflorescences 
erect, sessile at or near the mouth of their own spathe, spiciform, about 10 cm. 
long, cylindraceous, 2:5 cm. thick when covered with almost mature fruits; the 
axis of the inflorescence rather thick,  woolly-furfuraceous, with the appendicular
