The species was described, by Constantine Samuel Rafinesque. The species description was published in 1840, in the ''Autikon Botanikon.'' ''Luzula'' is a combination of the Latin verb'', lucére'' that means “a give light” and the Italian word ''lucciola'', which means “ a little light” or “to shine or sparkle”. The name refers to the shining light that is produced when the long, overlain hairs on the leaves are wet. ''Acuminata'' also stems from a Latin word, ''acuminatus'', which means “sharp” or “pointy”, referring to the leaf apex. ;Subspecies ''Luzula acuminata acuminata'' (Raf, 1840) ''Luzula acuminata carolinae'' (S.Watson, 2001)Distribution and habitat
