Leaflets not very numerous, sub-equidistant, 7-10 em. apart on each side, 25-32 cm. 
long, 3-45 cm. broad, lanceolate or elliptic-lanceolate, flat, with 5 costo, of these 
at least 4 spinulous above, all smooth beneath; margins spinulous-ciliate. Male spadiz 
diffuse ; spikelets spreading, comb-like, 15-25 mm. long, with 6-15 flatly bifarious 
horizontal flowers on each side. Female spadiz diffuse, with a few not very distant 
partial inflorescences; spikelets 45-6 cm. long, with 10-12 distichous flowers on 
each side, closely zig-zag sinuous between the flowers. Fruiting perianth shortly pedi- 
celliform. Fruit small, globose, 8-9 mm. in diam. Scales squarrose, in 12 series, 
broadly and superficially channelled, Seed small, globose, deeply pitted; albumen 
subruminate ; embryo basal. 
Lower Philippines. 
144. C. formosanus Becc.—Sheathed stem 3-3°5 cm. in diam. Leaves 1 m. and 
more long in the pinniferous part; rachis prickly lower down in the upper surface 
and smooth upwards, Leaflets not very numerous, distinctly geminate or ternate on 
each side of the rachis, elongate-lanceolate or oblanceolate, 20-30 em. long, 3-3°5 cm. 
broad, subulately acuminate from their upper third part, flat, with 3 rather slender on 
both surfaces smooth costz; margins spinulous-serrate. Male spadiz diffuse, termin- 
ating in a small tail-like aculeolate appendix; spikelets arched, spreading, inserted 
just at the mouth of their own spathe, broad, flattened, 2:3 cm, long with 8-10 flatly 
bifarious, 5-6 mm. long, ovoid-oblong flowers on each side. 
Formosa, 
145. €. Rumphii Bl.—Scandent and of moderate size. Leaves large. Leaflets rather 
remotely equidistant, about 75 em, long, 3°5-4 cm. broad, narrowly lanceolate, very 
acuminate, with the mid-costa and one nerve on each side of it bristly beneath; 
margins conspicuously ciliate. Female spadiz large, broadly panicled, shorter than 
the leaves, Fruit globose-oblong, beaked, the size of a musket bullet. 
| Amboina. : 
146. C. palustris Griff.—Scandent.  Sheathed stem 3-4 cm. in diam. Leaf-sheaths 
armed with laminar, scattered or subseriate spines. Leaves large; the upper ones of the 
adult plant cirriferous and with a short and sometimes almost obsolete petiole. Leaflets 
not very numerous, usually in pairs or ternate on each side of the rachis, with long 
vacant spaces interposed, firmly papyraceous, more or less broadly lanceolate or elliptic- 
lanceolate or oblanceolate with a bristly apex more or less concave-convex, shining 
above, with 5-7 costz, which are usually smooth on both surfaces, or the mid-costa 
only occasionally spinulous above; margins sparingly spinulous lower down, ciliate 
upwards. Male spadiz forming a large panicle, 1-1-5 m. long, with many rather 
approximate partial inflorescences; ultimate spikelets 1:5-2:5 cm. long with very 
crowded, bifarious, ovate, 4 mm. long flowers. Female spadix not very diffuse, 
with many rather approximate partial inflorescences, the largest of these 40-50 
cm. long, with 6-8 distichous spikelets on each side; the largest spikelets 8-10 
em. long with 12-13 flowers on each side, Female flowers about 4 mm. long. 
Fruiting perianth split not quite to the base. Fruit  ovoid.elliptic or subobovoid, 
shortly beaked, 15-18 mm. long, 10-12 mm. broad. „Scales flattish, very superficially 
channelled. Seed ovoid, irregularly pitted; albumen equable ; embryo basal
