Carex buekii is a rare species, native to Europe and the Middle East, although its full geographical distribution is poorly known. Attention is paid to the global occurrence of C buekii. Its situation and threat status is presented in relation to each country from which this species is known. Carex buekii forms four (rare) hybrids, each with other members within the section Phacocystis. Special attention is paid to the comparison of Carex buekii with the recently described Central European C. randalpina; the taxonomic problems of those two species are briefly discussed.
