Biology: Black (1943) recognised 2 varieties in S.Aust. -var. inversa and var. major Boott, Ill. Gen. Carex 4:151 (1867). Var. inversa is smaller (to 30 cm high), without the transverse bars on the utricle and recorded from SL, but the justification for separating these varieties requires investigation.
