Chorological notes of Carex L. (Cyperaceae) for the Flora of the Balkans, with emphasis in Albania

Relevant chorological notes of genus Carex L. (Cyperaceae) for the flora of the Balkans are provided, with an emphasis on Albania and adjacent countries (North Macedonia and Montenegro). Our findings include new national species records and/or confirmations for Albania, Montenegro and North Macedonia (C. agastachys, C. atrata, C. curvula, C. demissa, C. hispida, C. parviflora), as well as other interesting records of rare and/or endangered Carex species in Albania (C. castroviejoi, C. myosuroides). Eventually, we provide relevant comments in order to clarify the taxonomy, distribution and/or ecology of Carex sections Rhynchocystis (C. agastachys, C. pendula) and Aulocystis (C. ferruginea, C. kitaibeliana, C. lazarei) in the Balkans.
