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.^[4]
