usually near together, sometimes distant; gl. with a green mid-

(C. Mairit (C. and G.!), which has glumes with a scabrous 
point, fr. obsoletely nerved gradually narrowed into a setose- 
ciliated beak, is likely to oceur.]

Lowest bract frequently, but not always, reaching up to the bar- 
ren spike. Root sometimes creeping.—8. C. Hornschuchiana
