Abstract Specific rank, Carex tenuiculmis, is accorded
to the New Zealand endemic C. secta var. tenuiculmis. Carex
tenuiculmis is distinguished from C. secta by a tussock habit, red
leaves, shorter and scarcely branched inflorescence, the utricle with an
obviously winged and scabrid margin, and the utricle-beak entire or the cleft
minute. Different chromosome numbers are reported for C. secta and C.
tenuiculmis. Carex tenuiculmis grows in wetlands and is considered
to be endangered.
