Hab. Plains and elevated grounds of the Columbia, near the sea. Dr Scolder. Douglas. — Root tufted. 

 Culms caEspitose. Ij to 2 feet high. Leaves prmcipally radical, one-fourth the length of the culms, 3 or 4 

 on the culm, distant, but the culm is almost wholly concealed by their remarkably long, sheathing bases. 

 Panicle 5'6 inches long; branches slender, again divided, more or less long, and more or less patent. Spike- 

 lets small in proportion to the size of the panicle, green, glossy, smooth. Awns about equal in length to the 

 perianth. Glumes short and obtuse, especially the upper or inner one, which is about twice as long as the 

 outer one, yet not half so long as the floral valves. Inner valve of the floret as long as the outer, acute, flat at 

 the back, but the margins closely inflexed.
