DESCRIPTION OF SPECIES LTT 
g’. Slender; leaf-rachis smooth above; leaflets in groups 
of 2 to 4 on each side of the rachis, lanceolate, very 
long-acuminate to a filiform tip, 3- sub 5-costulate, 20 
to 30 cm long, 15 to 20 cm wide; female spadix very 
diffusely paniculate; spikelets filiform; fruit very small, 
spherical, 5 mm in diameter............ 29. C. microsphaerion. 
h*. Leaf-sheaths unarmed; leaflets glabrous on both surfaces. 
C. microsphaerion (forma typica). 
h*. Leaf-sheaths strongly armed with short spines; leaflets 
slightly bristiy-spinulous on one to three nerves on 
the upper surface...... C. microsphaerion var. spinosior. 
g. Rather slender; leaflets in distant groups of 3 to 9 on 
each side of the rachis, linear, 1-, sub 3-costulate, smooth 
on both surfaces, 20 to 25 cm long, 1 em wide; female 
spadix very diffuse and much branched; spikelets fili- 
form; fruiting perianth shortly pedicelliform; fruit very 
small elobeseuts 2 en ees eee ee 30. C. ramulosus. 
f. Leaflets very inequidistant, yet not distinctly grouped on 
each side of the rachis, the latter strongly prickly above, 
at least in its lower portion; leaflets elongate, linear- 
lanceolate, rigid, 3-costulate, more or less spinuliferous on 
the upper surface, smooth underneath, 30 to 32 cm long, 
20 to 25 mm wide; leaf-sheaths about 2 cm in diameter, 
armed with scattered, pale, acicular spines; male and 
female spadices shorter than the leaves, simply and spread- 
ineiy.sbranched 5.5 piers 2 ee 31. C. Vidalianus. 
c. Primary spathes very loosely sheathing, usually short, and more 
or less inflated in their upper part. The species of this group 
are difficult to discriminate if the specimens are not with mature 
fruits; the male spadices alone do not offer appreciable characters 
for specific distinction. 
d‘. Fruit very small, having convex scales, the latter only slightly 
or not at all grooved along the center and with the points not 
appressed or subsquarrose. 
e’. Leaf-sheaths armed with scattered slender spines or almost 
smooth; fruiting perianth pedicelliform, terete. 
jf’. Leaf-sheaths armed with scattered slender spines; primary 
spathes aculeolate; fruit ovoid or subobovoid, 6 mm long, 
3.5 to 4 mm thick, the scales arranged in fifteen longi- 
tudinal series............ 32. C. siphonospathus (forma typica). 
*. Leaf-sheaths almost spineless; primary spathes smooth; 
fruit with scales arranged in fifteen longitudinal series. 
C. siphonospathus var. sublaevis. 
f*. Fruit with scales in twelve longitudinal series; leaflets with 
five bristly nerves on the upper surface. 
C. siphonospathus var. oligolepis major.

f*. Smaller; fruit with scales in twelve longitudinal series; 
leaflets with three bristly nerves on the upper surface. 
C. siphonospathus var. oligolepis minor. 
f°. Primary spathes aculeolate; fruit with scales in eighteen 
longitudinal series............ C. siphonospathus var. polylepis.
