2. C. lancifolia, V. #. Br. Stem very slender, 1-1} lin. thick, 
with a few minute tubercles. Leaves much spreading, }—4 in. 
distant, small, glabrous; petiole 6-9 lin. long, sheathing nearly or 
quite to the top; apex of sheath rounded; blade 2}—4 in. long, 3-1 
in. broad, unequal-sided, lanceolate, slightly falcate, tapering to a long 
acuminate apex, mucronulate, cuneate-acute at the base; primary 
lateral nerves 9-11 on each side of the midrib, slightly prominent on 
both sides ; immersed glands numerous, linear, short, rather indistinct. 
Peduncles in pairs, terminal, }—1 in. long, ratherslender. Spathe ?-1 
in.-long, 3-4 lin. broad, oblong, obtuse, convolute to about half-way

3. C. insulana, V. 7. Br. Stem climbing, 14-2 lin. thick, 
minutely granulate-tuberculate on the older parts. Leaves spreading,

from the top, rather slender; apex of sheath prominent, rounded ; 
blade 24-53 in. long, 1-13 in. broad, lanceolate, unequal-sided, acumi- 
nate into a long very acute point, cuneately rounded in at the base ; 
primary lateral nerves 7-9 on each side of the midrib, the two lowest 
in a long sweeping curve running out to the margin, the 5th forming 
an intramarginal nerve about % of the distance between midrib and 
margin, the others uniting with these, all slightly prominent on both 
sides ; glands dot-like, or occasionally linear, sometimes wanting in the 
central part of the leaf, or entirely absent. Peduncle 1#—2 in. long, 
solitary or in pairs, terminal. Spathe about 1} in. long, oblong

Allied to C. scandens, Beauv., but readily distinguished by its narrower, more 
acuminate leaves, in which the immersed glands are usually dot-like, rarely linear, 
and usually occur towards the margins.
