A NEW OCCURRENCE OF OROBANCHE NANA NOE ON SZÁRSONLYÓ IN THE VILLÁNY HILLS
Abstract and Figures
On Szásomlyó in the Villáy Hills a new occurrence of Orobanche nana Noe, which was thought to be extinct, was observed. This paper compares the morphological features of Orobanche nana with those of the very similar Orobanche ramosa L., using data from lite ra tu re and specimens from herbaria. As an in te re st in science history and for showing some morphological features the author publishes some photos of herbarial specimens collected by the author herself. The paper also tre a ts the coenological and ecological characteristics of its habitat on Szásomlyó, on the basis of five classical coenological releves, using relative ecological indicator values and social behaviour types of species.

... Az Orobanche L. s. l. nemzetség európai fajszámát a korábbi szerzők eltérően ítélték meg, újabban a fajszám emelkedik, részben a meglévő taxonok szétbontása, részben új alakok leírása következtében.

Since the beginning of the 1990's specimens of Orobanche genus living on Knautia drymeia are known from the Kőszeg Mountains (NW Hungary), which were identified as O. reticulata WALLR. on the bases of Hungarian references (KIRÁLY 1996). Later it was stated (PUSCH 2000) that an Austrian 'O. reticulata' specimen living on Knautia is the same as O. pancicii BECK formerly known only from the Balkans. In 2005 it was confirmed that the plants from Kőszeg Mountains belongs to O. pancicii as well as later this year a new locality of the species was found near Szepetnek (Southwest Hungary). During the examination of the herbarium (BP) specimens from three new localities collected between 1945-1948 in Zala county (SW Hungary) were detected, moreover a specimen from 1933 from the surroundings of Kőszeg was found. In Hungary O. pancicii lives exclusively on Knautia drymeia and its localities are situated between the elevations of 150-450 m. In Kőszeg Mountains it exists in hornbeam-oak forests, where Knautia drymeia is one of the characteristic species of the herb layer. A part of these hornbeam-oak forests is developed on the territory of former chestnut groves consequently they are rich in herb species and full of forest edge elements. Near Szepetnek O. pancicii exists in secondary scrubbing meadow. On the bases of these new results, Hungarian data referring to O. reticulata must be modified as well. Knautia drymeia must be deleted from its host species list as in fact it lives only on some Carduus and Cirsium species.
Szársomlyó has the richest flora within the Villány Hills (Hungary) (approx. 800 species/3 km2). One of the most interesting species of the hill is the Vincetoxicum pannonicum, which was described by Professor Attila Borhidi in the last century. This Pannonian endemic taxon occurs exclusively on the southern slopes of the Buda Hills and the Szársomlyó Hill. The flagship species of the local flora is Colchicum hungaricum, which usually bursts into bloom at the end of winter. This perennial taxon with white perigone is distributed in the northern coasts of the Adriatic Sea, so the closest population of this relict colchicum can be found in some hundreds of kilometres away from the Villány Hills, in Dalmatia (Croatia).
