 Spikets almost sitting, and growing on one side of the stalk ;

 The Fl. Lapp, and Suec. certainly contains under the head 

 of Br. arvensis the synonyms of different plants, and the subject 

 has not yet been sufficiently examined. Mr. Lightfoot by his 

 reference to fl. dan. has demonstrated the existence of that var* 

 with us, but the plant of Scheuchzer, referred to in the Sp« pi-

 as Mr. Curtis has observed, is sufficient to distinguish it. Panicle
