The name Carex muricata subsp. lamprocarpa “Čelak.” (1879) is frequently used in floras for C. pairae F. W. Schultz when it is treated as a subspecies of C. muricata L. However, the combination C. muricata var. lamprocarpa was published by Wallroth in 1822. The corresponding specimen in Wallroth’s collection in PR, studied by L. Čelakovský and designated here as a lectotype, is C. muricata as it has the characteristic shiny utricles. So the combination C. muricata subsp. pairae (F. W. Schultz) Čelak. (1870) has to be used.
