length and number of flowers, those at the apex of the panicle are very acute and 
have 2-4 flowers only. Female flowers ovoid-subconical, acute with a flat base, 3 mm. 
long; the calyx boldly striately veined; the corolla polished, slightly longer than 
the calyx. Wouter flowers very much like the female, and only slightly smaller. 
Spathels very closely packed, bracteiform; involucrophorum and involucre similar, 
orbicular, shallowly cupular; the neuter flower. seems to be furnished also with a 
special small involucre. Fruit small, when very young conspicuously beaked ; scales 
convex, not grooved along the centre. The plant acquires a dark brown colour in 
herbarium specimens,

OsszrvaTions.—It is related to C. zonatus and especially to ©. rugosus, and the 
leaf-sheaths have the peculiar armament and ornamentation proper to these; but it is 
easily distinguishable by the singular disposition of the leaflets in horizontal distant 
pairs.

DrscsIPTION.—Seandent and slender.  Sheathed stem apparently as thick as a 
finger. Leaf-sheaths (judging from a very small portion) very scabrid and armed 
with small trianguler ascendant prickles. Leaves .... Male spadir .... Female spadix 
slender, flagelliform, very elongate, simply branched, with only 2-3 very distant 
partial inflorescences and terminating in a very long, filiform, minutely and 
irregularly clawed flagellum; on the whole the entire female spadix is 2m. and over 
in length. The lowest spathe is about 30-35 cm. long, 7-8 mm. broad, closely 
sheathing a long way up, strongly flattened, with the edges acute and spinescent, 
flattish and smooth on the inner side, and more or less prickly-scabrid externally, 
split open in its upper part into a narrow ear-like acuminate limb, which is 
fringed at its apex with peculiar, flaccid, spine-like paleolæ, 15-20 up to 30 mm. 
long. Upper primary spathes longer than the lowest, slightly flattened and subterete, 
almost smooth, very closely sheathing except at their upper end, where they are 
also expanded into an ear-like lanceolate limb, which is also edged at its apex 
with the peculiar spine-like paleolæ; the basal part of the upper spathes 
gradually passes into the main axis of the spadix, which is angular and 
more or less armed with scattered claws or at times smooth. The partial 
inflorescences are’ attached above the mouth ‘of their respective spathes, are 
at first erect, but when loaded with fruits become spreading and have a 
distinct axillary callus, are 15-30 cm. long, have a rigid, slightly sinuous, slender 
axial part, from which alternately part right and left 10-12 spreading or horizontal 
spikelets; secondary spathes tubular, frequently obsoletely angular, smooth, very 
closely sheathing, truncate and ciliolate at their mouth and produced at one side 
into a short triangular point. Spikelets inserted above the mouth of their respective 
spathes with a distinct axillary callus, rigid, slender, glabrescent : the lowest and
