1. Setaria glauca Beau v. Yellow Foxtail or Pigeon-grass 



Plate XVI. Figure 62. 

 An erect annual one to two feet high, with flat leaves and a 

 bristly cylindrical spike-like, densely-flowered panicle, one to three 

 inches long. Culm scabrous just below the panicle, otherwise 

 smooth. Sheaths smooth; ligule a dense fringe of short hairs; 

 leaf-blade three to ten inches long, two to five lines wide, nearly 

 smooth on the dorsal surface, very scabrous on the upper surface 

 and margins, and occasionally pilose near the base. Axis of the 

 panicle densely pubescent. Bristles five to ten to each spikelet, 

 yellowish or rarely purplish. Spikelets ovoid, about one and one- 

 half lines long. First glume about one half a line long, three- 

 nerved, secQnd nearly half the length of the spikelet, five-nerved; 

 the third five-nerved and as long as the transversely rugose flow- 

 ering glume. 



This is a well-known weed, growing everywhere in cultivated 

 grounds. It sends up a number of stems from a single root, each 

 bearing a cylindrical "bristly" head. It continues to bloom 

 throughout the season from June to October. 



2. Setaria viridis Beauv. Green Foxtail, Wild Millet. 



Plate XVI. Figure 63. 



Similar in habit to Yellow Foxtail. Spikelets about one line 

 long, the nearly equal second and third glumes about the length of 

 the minutely punctate-striate (not transversely rugose) fourth 

 glume. 



This is an introduced grass like the Yellow Foxtail, and has be- 

 come a common weed in all cultivated grounds. It begins to bloom 

 a little earlier than the Yellow Foxtail. The cylindrical panicles 

 are more tapering toward the apex, the more numerous spikelets 

 are smaller and the bristles are usually green. 



3. Setaria Italica Kunth. Italian or Golden Millet. 



Plate XVI. Figure 61. 

 This exists here only in cultivation. It is distinguished from the 

 German Millet by its larger, longer, more loosely-flowered and us- 

 ually nodding panicles. The millets of this class, that is species 

 or varieties of Setaria, are ready to cut sixty to sixty-five days 

 from time of sowing. When cut just as heading out, and before 

 blooming, they make a valuable and safe forage; but in more ad- 

 vanced stages the feeder should be exceedingly careful, for when 

 ripe these millets act injuriously upon the kidneys. They are the 

 refuge of the poor farmer whose other forage crops have failed. 

 They are sometimes grown here for the seed, and the product is 

 often used as bird and poultry food. 



4. Setaria Germanica, German or Hungarian Millet. 



This is regarded by botanists as only a variety of the Italian Millet,
