"J. straminea Fourn. is readily distinguished from /. jj^^osa 

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

 inflorescence, more slender and proportionately much longer spike- 

 lets. In J. pilosa the glumes are grown to the axis for almost their 

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

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