Carex austroflaccida was published as a replacement name for Uncinia flaccida Blake, in the belief that  the name flaccida was unavailable in Carex because of the earlier combination Carex flaccida Sw. However, Swartz’s name is invalid, and therefore the epithet flaccida is currently available in Carex. The name Carex austroflaccida is retained here pending the publication of the combination of the name in Carex.
