116 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
182. C. pachystachys Warb.—Robust, scandent. Leaves rather large; the cirrus 
robust; rachis prickly above. Leaflets rather numerous, equidistant, about 4 cm. apart, 
longitudinally plicate, narrowly lanceolate; 20-25 cm. long, 2-2°5 em. broad, with 
the mid-costa sparingly bristly above, smooth beneath;  side-nerves slender and 
smooth on both surfaces; margins conspicuously ciliate. Female spadiz robust, with 
rather large partial inflorescences; spikelets strongly arched, their axis thick, sub- 
terete, vermiform, the largest about 15 cm. long, with 7 pairs of female flowers on 
each side, the spathels usually subtending two equally evolute female flowers. 
Fruit subglobose-ovoid or subturbinate, suddenly conically beaked, 15-17 mm, long, 
10-12 mm. broad. Scales shining, in 17-18 series, strongly convex, deeply channelled. 
Seed globular, deeply ruminate. 
Celebes. 
183. C. didymocarpus Warb.—Robust, scandent. Leaves large, the cirrus robust, 
up to 2 m. in length. oeajflets lanceolate-ensiform, longitudinally plicate, 8-10 cm. 
apart, 40 and more cm. long, 4 cm. broad, the mid-costa sparingly bristly above, 
smooth beneath; secondary nerves slender and smooth on both surfaces; margins 
spinulous. Female spadiz large and diffuse, with long nodding or pendulous partial 
inflorescences which carry 6-7 rather distant spikelets on each side; spikelets 
vermicular, up to 25 cm. long with 15-20 pairs of female flowers on each side 
usually the spathels subtending two equally evolute female flowers. Fruit subglobose- 
ovoid or subturbinate, suddenly topped by a 2 mm. long cylindraceous beak. 
Scales in 15 series, strongly convex, shining, deeply channelled. Seed globular ; 
albumen deeply ruminate. 
Celebes. | 
184. C melanoloma Mart.—Slender, scandent. Leaf sheaths T 129 mm. in diam., 
armed with scattered spines. Leaves small, 30-50 em. long in the pinniferous part; 
the cirrus slender; petiole short or very short. Leaflets 10-20 in all, 10-12 em. long, 
1:5-2:5 cm. broad, usually in remote pairs on each side of the rachis, lanceolate or 
oblanceolate, 3-or sub-5-costulate, smooth on both surfaces. Male and female spadices 
very similar, very simple, with a few spikelets on each side of the main axis; 
spikelets 5-6 cm. long, with few distant spreading flowers on each side. Frut 
elongate-ellipsoid, distinctly beaked, 18-21 mm. long, 10-14 mm. broad, Scales in 
15-18 series, faintly channelled, straw coloured with a black marginal line and 
tip. Seed narrowly oblong, deeply pitted; albumen subruminate; embryo basal. 
Java. 
185. C. siphonospathus Mart.—Scandent.  LLeaf-sheaths 2-4 cm. in diam., more 
or less armed with slender acicular spines. Leaves (of the upper part of the adult 
and fertile plant) 1 m. and more long in the pinniferous part with a cirrus about 
as long; petiole rather long. Leaflets numerous, equidistant or nearly so, linear or 
linear-lanceolate, 20-35 cm. long, 10-18 mm. broad, with 3-5 bristly coste, Mak 
spadiz :6-1 m. long, narrow, terminating in a subulate smooth tail-like apex, with 
several small partial inflorescences, each issuing from a tubular, very loosely sheathing 
or rather inflate spathe; spikelets with a very slender, filiform. zig-zag sinuous axis, 
10-15 mm. long, with 8-10 flowers in all. Female spadiz similar to the male one,
