 spathes narrow tubular compressed and truncate partial sparingly shortly 

 spiny or unarmed, spikes H-3 in., male spathellules very short crowded,

 pressed, with a short erect limb and short spines on the keels, partial 1^-1 in. long. 

 Spathellules of male fl. very short and crowded, of fern. ^ in. long. Mate fl. g - in. 

 long, calyx 3-fid. Fruit unknown. 



25. C. nicobaricus, Becc.; leaflets very many equidistant linear- 

 ensiform long-acuminate sparsely setose on the median costa only on both 

 surfaces lateral costse slender naked, petiole channelled above armed with 

 long straight marginal spines and short _claws on the back, sheath very 

 pale at first scurfy densely armed with very unequal long flat spines and

NICOBAR ISLANDS, E. H. Man. 



A very slender species, with varnished internodes i- in. diam. Leaflets 7-8 

 by about i in., shilling above. Spadix and fruit unknown. Flagelli exceedingly 

 slender. Appears to be allied to C. delicatulus, from which it is distinguished by 

 the leaflets being setose only on the median costa. I have seen no specimen.
