Jakab, Gusztáv: Contributions to the knowledge of the bryophyte flora of the SE Carpathians (Romania)

Studio bot. hung. 29, pp. 49-57, 1998 (1999) CONTRIBUTIONS TO THE KNOWLEDGE OF THE BRYOPHYTE FLORA OF THE SE CARPATHIANS (ROMANIA) G. JAKAB Directorate of the Körös-Maros National Park H-5541 Szarvas, Anna-liget, Pf. 72, Hungary The bryophytes collected in the Kőhát (1997) and Lápos (1998) mountains have been recorded. These bryologically neglected areas have provided some interesting data to the floristical knowledge of the Carpathians. The boreal elements are widespread here (like in the higher mountains of the SE Carpathians), and numerous arctic elements occur as well (e.g. Sphagnum cuspidatum, S. riparium, S. warnstorfii, Tayloria tenuis). The rare Sphagnum pylaesii is reported form the Carpathians for the first time. Other interesting species are Calypogeia fissa, Cololejeunea calcarea, Hygrohypnum eugyrium, Leucobryum juniperoideum, Plagiobryum zierii, Porella cordaeana and Raclula lindenbergiana. Key words: bryophytes, Carpathians, enumeration, Romania, Transylvania INTRODUCTION Rozsály-Kőhát Mts (Muntii Ignis) and Lápos Mts (Muntii Lapusului) in the SE Carpathians (Romania) are bryologically neglected territories (cf. STEFUREAC 1986). In spite of the investigations by Á. Boros and L. Vajda (BOROS 1942-62, 1951, BOROS and VAJDA 1967, 1968) and some recent bryologists (KÓSA 1997) we only had limited information on the bryophytes of these areas. In 1997 and in 1998 I had the opportunity to conduct an investigation which resulted in more than 1200 collected specimens during three expeditions. In this article I intend to outline the main bryological features of these mountains. MATERIALS AND METHODS The neighbouring Rozsály-Kőhát Mts and Lápos Mts are a part of the inner volcanic ridge of the SE Carpathians. This is a Sarmatian-Pliocene volcanic ridge running from the Vihorlát Mts to the Gutin Mts on the southeastern edge of the Great Hungarian Plain. In the southern part it is connected to the inner flysh-zone of the Carpathians (HAJDÚ-MOHAROS 1996). Though the mountains sometimes reach 1000 metres above sea level (e.g. Gutin - 1445 m, "Fenyves-csúcs" ("Fenyves" Peak) - 1353 m, "Cigány-kő" ("Cigány" Rock) - 1224 m), the mean elev-
