''J. sfrotiiinva Fourn. is readily distinguished from ,1. inloxa 

 Scribn. by its more slender habit, less rigid leaves, less crowded 

 inllorescence, more slender and proportionately mueli longer spike-

 entire length, and there are paleas or rudimentary pistils of a second 

 flower within the floral cavities.'' Scribner, 1. c.
