 MOUNTAIN RICE.— A slender perennial 1.5-5 dm. (6'^20') high, with narrow, 

 simple, few-flowered panicles 6-10 cm. (2^'-4') long. Empty glumes (a) 6-8 mm. 

 (3"-4") long, abruptly pointed; flowering glume (6,c) nearly as long as the 

 empty ones, thinly pilose; callus barbate, short and blunt; awn slightly twisted, 

 10-12 mm. (5"-6") long. The basal leaves, which are 5-7 mm. (2i"-3^") wide, 

 often overtop the culm.— Woods, Newfoundland, Massachusetts, and New Jersey 

 to Minnesota and British Columbia, and southward in the Rockies to New 

 Mexico. April to July. 



This grass is evergreen, and in the northern parts of New England, where it 

 is known as "winter grass," it affords excellent grazing.
