sheaths smooth or very scantily armed. Leaves smali, about 45 em. long; petiole 
very short. Leaflets few, usually paired on each side of the rachis, the pairs sub-

decompound, arcuate, Female spadix simply decompound, ending in a slender clawed 
flagellum; the largest spikelets: (the lowest) 4-5 cm. long with 5-6 remote flowers 
on each side; involuerophorum more or less distinctly pedicellate. Fruiting perianth 
distinctly pedicelliform, rz: globose, 8-10 mm. in diam. Scales in 21-23. series 
faintly channelled along the middle.

87. C. acanthospathus Griff.—Subseandent, rather robust. Sheathed stem 3-5 cm.

broad-based, solitary or confluent and subseriate spines. eaves large, as much as 
1:5 m. long; petiole short. Leaflets large, as much as 45 cm. long, 5-6 cm. broad, 
many-costate and plicate, lanceolate, remote, inequidistant, never aggregate or paired. 
Spadices elongate, flagelliform; primary spathes coriaceous, elongate, closely sheathing, 
more or less armed with short conic prickles or almost smooth; larger female

in two somewhat unilateral series. Fruiting perianth pedicelliform, thick and short. 
Fruit broadly ovoid, suddenly conically beaked, 24-25 mm. long, including the beak 
and the perianth 14-15 mm. broad. Scales subshining, in 15 series, cinnamon brown, 
superficially channelled along the middle. Seed deeply pitted on the back; albumen 
subruminate; embryo basal.

88. C. Feanus Bece.—Scandent.  Sheathed stem 16-22 cm. in diam.  Leaf-sheaths 
mottled, armed with irregular subdimidiate-conic prickles, Leaves about 1 m. long, 
petiole very short or 0.  Leafleis few (6-8 on each side), inequidistant, but not 
fascicled; rather remote, somewhat concavo-convex, elliptic-lanceolate or oblanceolate, 
many-costulate, the eostæ inconspicuously spinulous above, naked beneath, 20-32 cm. 
long, 5-7 cm. broad. Female spadiz flagelliform, elongate; primary spathes very 
elongate, entire, very closely sheathing, sparingly prickly; lower partial inflorescences 
(the largest) 10-14 cm, long with 3-4 scorpioid spikelets on each side; the flowers 
slightly pointing "owards. Fruiting perianth pedicelliform. Fruit broadly ovoid, suddenly, 
conically beaked, 17-18 mm. long, 12 mm. in diam. Scaks in 15 series, opaque,

89- C. bacularis Bece.—Stem erect, about 2 cm. in diam.  Zeaves about 
2 m. long.  Leaf-sheaihs armed with long spines, open on the ventral side and 
gradually passing into the petiole; this long and armed at the base with long 
horizontal spines; rachis smooth beneath. Leaflets equidistant, narrowly lanceolate, 
concolorous and shining on both surfaces, with 3 acute costz which are spinulous above 
and smooth beneath. Male and female spadices erect unarmed; primary  spathes
