A slender annual. 60-120 cm. higli. bearing a narrow panicle of 

 a few nodding spikelets. Spikelets 2- or more-flowered, 2.5-3 cm. 

 long; empty glumes 9- and 11-nerved respectively; floral glume 

 of the lower floret 2.5 cm. long, extending into 2-3 slender teeth, 

 glume clothed on the lower half with numerous long bristles, awn 

 6 cm. long, stout, lower half brown and twisted. There are varie- 

 ties differing from the above description in several respects. 



A native of Barbary, sometimes cultivated as a curiosity. When 

 moistened, the long awns slowly turn around till straight; in this 

 way the spikelets move about. Said also to be used as an artificial 

 fly as a bait for fish.

Spikelets 2-flowered; empty glumes 7-9-nerved; floral glume 

 and pedicels glabrous. Smaller and more slender tlian A. fatua; 

 leaves sometimes hairy; panicle unilateral, rays fewer; floral glume 

 more deeply bifid, segment awned. 



Found in similar places with A. fatua. Description mainly 

 taken from Hooker's Flora of the British Islands. By Hooker and 

 some others it is considered a mere variety of A. fatua. 



Not yet known in North America, but may be looked for. 

 Here mentioned because some consider it the parent form of our 

 cultivated oats.
