Notes: FNA23: "Carex brevior seems to display an unusually broad, aneuploid chromosome series that does not readily correlated with any features of external morphology (P. E. Rothrock and A. A. Reznicek 1998). The chromosome variation may, however, have a geographic relationship. Among the plants observed, the lowest number came from northeast Texas while the highest number (n = 34) came from Manitoba (Á. Löve and D. Löve 1981b).
Records of Carex brevior from ruderal habitats east and south of its main range are likely introductions."
