78 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
C. javensis var. acicularis Becc.—Very slender.  Leaf-sheaths with short or rather 
long, straight spines. Leaves short with only 2 pairs of leaflets which are approximate 
to the terminal pair; the basal pair transformed into two opposite, long, acicular 
spines. Female spadiz shorter than the leaves.—Perhaps a distinct species. 
Borneo. 
32. C. filiformis Becc.—Excessively slender. Sheathed stem 3-5 mm. in diam.; 
naked canes sometimes not more than 2 mm. in diam. Leaf-sheaths smooth, or with 
very few hooked prickles. Leaves very delicate, 25-40 cm. long; the petiole 
very short. Leaflets 5-6 on each side, somewhat inequidistant, very narrowly lanceolate, 
8-12 mm. long, 8-14 mm. broad, those of the terminal pair very highly connate. 
Male spadix filiform, very slender; partial inflorescences reduced to one spikelet. 
Mountains of Borneo. 
83. C. corrugatus Bece.—Sheathed stem 4-5 mm. in diam.  Leaf-sheaths not 
prickly, but marked by many, approximate, prominent and annular ridges. Leaves 
30-85 cm. long; petiole very short. Leaflets very few, 5 on each side, perfectly 
opposite and forming remote pairs, elliptic-lanceolate, 3-costulate, 12-13 om. long, 
2*0 em. broad; those of the terminal pair united to about the middle. ` : 
Borneo. 
34, C. papuanus Becc.—Very slender. Sheathed stem 6-8 mm. in diam. Leaf- 
sheaths sprinkled with very small ascending, tuberculiform prickles. Leaves short (about 
30 cm long); the petiole about 2 em. long. Leaflets few, 6-7 on each side, clustered 
in about 4 remote fascicles of 3-4 each, spreading, elliptic-lanceolate or broadly 
oblanceolate, suddenly subulately acuminate, 5-costulate, quite naked on both surfaces 
and at the margins, those of the terminal pair connate to about the middle. 
New Guinea. 
35. C. filipendulus Bece.—Sheathed stem 1-1°5 cm. in diam.  Leaf-sheaths armed 
with short, or 5-10 mm. long or subtuberculiform, scattered or slightly confluent 
spines. Leaves *-l m. long; the petiole short or long. Leaflets very few, 5-8 in 
all, elongate oblong, 25-40 cm. long, 5-10 cm. broad, 5-9-costate, naked on both 
surfaces, those of the terminal pair confluent by their bases. Male and female spadices 
similar, simply decompound, filiform, very long (1-L8 m.). Fruit small, about 12 
mm. long, broadly conical-ovate. | ' 
Malayan Peninsula. 
36. C. gonospermus Becc.—Sheathed stem about 15 mm. in diam. Leaf-sheaths 
densely armed with straight, spreading spines. Leaves about 50 cm. long, the petiole 
short. Leaflets very few, 6 in all, oblong or spathulate-oblong, 20-22 cm. long, 4:5—5:5 
em, broad, 5-costate, quite naked on both surfaces, those of the terminal pair 
about as large as the side ones, highly connate. Female spadiz with a comparatively 
rigid and stout axis and with abbreviate, densely flowered partial inflorescences. Fruit
