Carex venusta has been divided into two varieties: one with glabrous perigynia and slightly smaller perigynia and the typical variety with pubescent perigynia. Both varieties are named from types from the Gulf coastal plain. Varieties are not recognized here because variability in the characters used to separate them is greater within populations than between populations. However, there do seem to be two taxonomic entities within this species: one with a distribution from Texas to North Carolina and the other with a distribution from North Carolina to Long Island, New York. The two groups differ slightly in perigynium size and shape and have different, but overlapping, series of chromosome numbers and strikingly different allozyme patterns (M. J. Waterway 1988). The northern group always has glabrous perigynia while the southern group has both glabrous and pubescent perigynia, often in the same population. Whether to recognize these variants as varieties of C. venusta or as distinct species is the subject of ongoing study. Hybrids between both groups and C. debilis have been confirmed.
