 79. 1893. KELLOGG'S SPEAR-GRASS.— A slender, erect or ascending perennial 

 3-9 dm. (l°-3°) high, with rather long, flat leaves and open pyramidal panicles 

 7-10 cm. (2i'-4') long. Sheaths nearly smooth, about equaling the internodes: 

 leaf-blades plane or loosely involute, 15-30 cm. (6'-12') long, 4-8 mm. (2"-4") 

 wide. Spikelets (a) about 6 mm. (3") long, loosely 2 to 8 flowered; empty 

 glumes ovate, acute, scabrous on the keels, the first 1-nerved, shorter than the 

 second 3-nerved one; flowering glumes (6) about 4 mm. (2") long, 5-nerved 

 nearly to the apex, the midnerve barely excurrent, smooth, except for the long, 

 thin web at the base. Palea 2-toothed, nearly smooth on the green keels, 

 slightly shorter than the glume.— California (4705 Bolander).
