Vernacular Name. — Tchye (Nicobars). 



A very slender plant, with varnished internodes, ^-^ inch in dia- 

 meter. Leaflets very many, 7-8^ inches long, abont ^ inch broad, 

 equidistant, linear-ensiform, long-acuminate, sparsely setose on 

 the median costa only on both surfaces, shining above, lateral 

 costal slender, naked ; petiole channelled above, armed with long, 

 straight, marginal spines and short claws on the back, sheath very 

 pale, at first scurfy, deuselj' armed with very unequal, long, flab 

 spines and shoi't claws. Flagelli exceedingly slender. Spadix and

In Beccari's opinion this species seems to be allied to C. deli- 

 catulus, from which it is distinguished b}^ the leaflets being setose 

 only on the median costa. 



Habitat. — Nicobar Islands. 



Uses. — It is much used b}^ the natives and is in great demand 

 by ship-traders who take it to the Straits (ex Beccari).
