 plant emerging. Leaves linear, smooth. Spikes three-fold. 

 Exterior valve of the calyces with a long-, waved, ensiform

A native of Bengal, where it is found floating on pools of 

 sweet water, and blossoming about the close of the rains in 

 October. 



Culms appear to be perennial, a fathom or two long, joint- 

 ed, as thick as the little finger, floating. Leaves linear, acute, 

 from one to two feet long, margins backwardly hispid, in 

 other respects smooth. Spikes terminal, three in the only plant 

 that has yet blossomed in this garden, each about six or eight 

 inches long, a little compressed ; when the flowers expand 

 about noon they appear like Chevaux de frise, at other times 

 they appear smooth. Flowers in pairs, one sessile, contain- 

 ing one hermaphrodite, and one male floret, the other pedicel- 

 led and neuter, or with two male florets. Calyx two-valved; 

 exterior valve rigid, with hispid margins and long, flat, wav- 

 ed, hispid margined, ensiform points; inner valve boat-shap- 

 ed with a flat hispid keel. Corols of each floret two-valved.
