Soft Chess. Bromus hordeaceus L. {Bromus 

 mollis L.) This plant is becoming frequent in 

 waste places; an annual, 10-45 cm. high. The 

 whole plant is soft hairy. Introduced from 

 Europe. 



Field Chess. Bromus arvensis L. and 

 Smooth Brome-grass. Bromus racemosus L. 

 Mentioned in Bulletin 260, are only rarely met 

 with in this country. They have much the 

 appearance of the common chess of our wheat 

 fields, excepting the spikelets are softer and 

 the awns longer. Some authors believe these 

 three are mere forms of the same species. All 

 of them are natives of Europe.

Chess, Cheat. Bromus secalinus L. Too 

 common where it thrives with winter wheat, 

 because like wheat, it needs to make some 

 growth in autumn and matures in summer 

 ready for harvesting and threshing with the 

 wheat from which it is not easily wholly sep- 

 arated. 



Specimens of this plant are occasionally met 

 with in the field and harvested with red clover 

 cut for sesd. After threshing it goes with 

 clover seed into a machine for a thorough 

 rubbing which takes off some of the adherent 

 inner chaff and often breaks off a little from 

 one or both ends of the grain. Grains of chess 

 thus mutilated are not uncommonly found 

 mixed with clover seed and the two are sown 

 at the same time. Introduced from Europe.
