Description

This species resembles '' Carex umbellata'' and '' Carex nigromarginata''. ''C. reznicekii'' can be readily distinguished from ''C. umbellata'' by the absence of basal spikes observable on ''C. reznicekii''. ''C. reznicekii'' most strongly resembles ''C. nigromarginata'', but can be differentiated by several factors, including ''C. reznicekii's'' narrower leaves and more-or-less uniform culm lengths. ''C. reznicekii's'' species status and distribution was determined in part through the use of herbaria records, where many instances of ''C. reznicekii'' were erroneously identified as ''C. umbellata'' and ''C. nigromarginata''.
