GLUMACE^ 407 



nearly stalkless, hairy below the middle, half as long 

 as the awn, which is dark and twisted. The lowest 

 flowering glume has the awn on the middle of the 

 back, and nearly twice as long as the glume, being 

 male only. The upper flowering glume is perfect, 

 and may have a small awn near the top. The 

 lodicules are lance-shaped, with marginal teeth. 

 There are three stamens. The styles are short and 

 distinct. The stigmas are feathery. The caryopsis is 

 downy, and enclosed in the flowering glume and palea. 



In height the False Oat Grass is 2 to 3 ft. It flowers 

 from June to July, and is a herbaceous perennial. 



As in other grasses the flowers are pollinated by 

 the agency of the wind, the stigmas being adapted 

 for that purpose, being large and feathery. 



Likewise the fruit, being light, is adapted to 

 dispersal by the same agency, being readily blown 

 away, as it is loosely enclosed in the glume.
