20 cm. long and 15-20 mm. broad ; those of the terminal group somewhat 
smaller; the two terminal are the smallest, free, or more or less connate, 
at the base. Male and female spadices similar, flagelliform, very long and 
slender, with a very few distant partial inflorescences ; primary spathes very 
narrowly tubular and elongate, very closely sheathing, more or less armed 
with scattered small claws; the lowest slightly compressed, the others 
cylindraceous. Male partial inflorescences (primary branches) zigzag 
sinuous, spreading, inserted outside their respective spathes with a distinct 
axillary callus ; the lowest 18-20 cm. long, with 7-8 rather distant spikelets 
on each side; the upper ones gradually shorter, and with fewer spikelets; 
secondary spathes 8-10 mm. long, smooth or at times very slightly spinulous, 
tubular-infundibuliform, or ‘with a narrow flattened base, and slightly 
enlarged above, very closely sheathing, obliquely truncate and glabrous at 
the mouth, where acute at one side; spikelets flattened, 6 mm. broad, comb- 
like with very approximate or contiguous bifarious flowers ; spikelets 
strongly deflexed, inserted just at the mouths of their respective spathes ; 
the lower spikelets 15-18 mm. long, bearing 13-15 flowers on each side; the 
others gradually shorter; spathels bracteiform, broad, concave, acute, strongly 
striately-veined ; involucre cupular, obsoletely two-keeled and two-tvothed 
on the side next to the axis. Male flowers very close together, ovate, sub- 
acute, 2°5 mm. long; the calyx deeply 3-lobed, strongly striately-veined ; 
the corolla twice as long as the calyx. Female spadiz has shorter partial 
inflorescences and fewer but larger spikelets than the male spadix; the 
largest (lowest) spikelets are 4~5 cm. long, and carry 8-10 flowers on each 
side; spathels broadly infundibuliform, truncate; involucrophorum obliquely 
campanulate ; involucre deeply cupular, tetencnté, as long as the involucro- 
phorum ; areola of the neuter flower rather conspicuous, subcupular. Female 
flowers ovate, inserted at an angle of about 45°, Fruiting perianth almost 
explanate, not pedicelliform. rwit broadly ovoid-elliptical, 17-18 mm. long 
(not taking into account the beak), 15 mm. broad, equally rounded at both 
ends, suddenly topped by a beak 2°5 mm. long; scales in 21 longitudinal 
series, rather deeply grooved along the centre, straw-yellowish with a very 
narrow dark brown marginal line; tip bluntish. Seed irregularly globose, 
with homogeneous albumen. 
Hab. Arfak Mts., Angi lakes, common all through the forest round ? lake 
at 7000-8000’. “A small rotang, excellent for tying.” 5977 (9 type- 
specimens) with the sheathed stem 8-10 mm. in diam. and rather densely 
prickly leaf-sheaths. The male plant (6144, Dec., Mt. Arfak, 5000’ on 
‘the S.W. ridge, scrambling in high forest) : very slender; sheathed stem 
8-10 mm. in diam.; leaf-sheaths nearly smooth. 
It is evidently relate to the Australian C. Muelleri, from which it mainly 
differs in the leaflets not being distinctly 3-costulate, and in the female spadix
