This species is readily separated from C. lonyus, Linn, (with which it has been 

 greatly confused) by the glumes standing altogetlier separate in fruit with their 

 margins inrolled. The .species is so close to the Indian C. tegetiim, Eoxb., that I can 

 allege no difference except the remarkable roundness of the stem in C . schimper ianus^ 

 which character distinguishes it also from its African neighbours.
