Other info. - This fairly distinctive species can be found mainly in the southern 1/3 of Missouri. The plant can be identified by its spreading inflorescence of compressed spikelets. The scales of the spikelets overlap and hide the linear and slightly curved (falcate) fruits. The scales and fruits of the spikelets are shed individually from the base, ultimately leaving a naked axis.
