Species. \. alopecuroidetim. (The trivial name of ^Z- 

 gantevm given by Walter and retained by Persoon, can 

 only be used wih propriety relative to the genus with 

 which Walter at first associated it; as a Sacchamm, which 

 it is, althoui'h indeed tall, it is alm(;st every way iiiferior 

 in size to the other species of tiie genus ) 2. brevibarbe.
