"Seeds" 1-5 to 2-5 mm. long. Outer palea three-nerved, 

 each, nerve hairy on its lower half. The inner palea is fringed 

 with finer and more numerous hairs than in Poa pratensis, and the 

 outer palea also spreads more widely open. Rachilla smooth, 

 cylindrical, outstanding. A delicate "web" of white hairs is pre- 

 sent at the base of the palea in "uncleaned" samples. (Fig. 138.)

Poa distans, L. (Reflexed Meadow-grass.) A somewhat rare 

 perennial with culms from 12-18 inches high. Flowers about 

 July. The rachis of the panicle is rough, and its lower branches 

 become obliquely bent downwards after flowering. Spikelets 

 linear-lanceolate, 4-7 flowered. The outer palea five-nerved, 

 and without a "web" at its base.
