Contributions to the distribution of Arabis nemorensis (Cruciferae) in Hungary
155-169Views:102Arabis nemorensis is a poorly-known species with sparse and mostly uncertain literature records in Hungary. A complete list of its known occurrences was presented in Soó’s synopsis in 1968. A few new records of this taxon have been reported since then. In the present study all literature records were evaluated by means of revision of Hungarian herbarium materials. Several vouchers were succesfully traced, and their identity as A. nemorensis was confirmed (Baja, Ercsi, Lesenceistvánd, Miskolc, Nagykanizsa, Szigetújfalu). In other cases, the putative vouchers belonged to A. hirsuta or A. sagitatta, thus the corresponding literature records proved to be erroneous (Balatonmáriafürdő-alsó, Gyenesdiás, Kőszeg, Vasboldogasszony, Zalaújlak). On the other hand, hitherto unknown Hungarian localities of A. nemorensis were revealed, specifically in the Bükk Mts. (Eger, Kács), the Bakony Mts. (Márkó), in the western Balaton region (Hahót, Hévíz, Keszthely-Fenékpuszta, Nyirád, Tapolca) and the Hungarian Plains (Csákvár, Debrecen, Egeralja, Fertőd-Eszterháza, Kiskőrös, Lébény, Ócsa, Sárszentmihály, Szigetszentmiklós). The species appeared to be new for the phytogeographical regions Bakonyicum and Nyírségense. Additionally, a few specimens of A. nemorensis collected outside the territory of present-day Hungary were revised in BP. The historical occurrence of the species at Torja (Turia in Romania) is documented by two specimens (Schur, 1853, as A. gerardi; Jávorka & Keller, 1943, as A. hirsuta). Another specimen that was collected in 1879 at Óbecse (Bečej) and labelled as A. glastifolia by Kovács was found to be A. nemorensis too. Since the identity of Schneller’s literature record (1858) from Futak is uncertain, Kovács’s specimen is currently the only, though historical record of this species from Vojvodina province in Serbia. Further specimens of A. nemorensis were discovered in the collections of Lengyel. They were collected and labelled as A. sagittata near Pomogy (Pamhagen) in 1910 (and questionably in 1919), probably representing the first gathering of A. nemorensis from Burgenland state in Austria.

On the former occurrence of Calla palustris in Hungary
200-210Views:1700The origin of a more than 150 years old herbarium specimen of Calla palustris L. stored in JPU is reconsidered in this study. According to the information on its label, the specimen was collected in 1856 at Lake Velence, close to Székesfehérvár city (central Hungary). Some Hungarian botanists are skeptical about the authenticity of this record. Based on the current occurrences of some remarkable swamp species (e.g. Carex pseudocyperus, Liparis loeselii, Sphagnum spp.) and habitat types (e.g. willow carrs and swamp forests) at the lake, as well as the habitat preference of bog arum, there is no reason to question the former occurrence of the species here or even in other Hungarian localities. The content and accuracy of the examined voucher meet the expectations of floristic data. However, in the absence of recent data the species can be considered extinct from Hungary.

The ‘rediscovery’ of the Birdsfoot Fenugreek (Trifolium ornithopodioides (L.) SM.) in the Hortobágy, Hungary
207–212Views:314In 2009, the first author discovered an unknown population of Trifolium ornithopodioides in the Ágota-puszta of Hortobágy plain. In 2016, the second author found an another population in the vicinity of Karcag (Ecse-zug puszta). Up to now there was only one published occurrence of this species from the region. The specimen collected by Szujkó-Lacza Júlia, Kováts Dezső and Fekete Gábor in 1974 was deposited in the herbarium of the Hungarian Natural History Museum (BP), but this incomplete specimen was misidentified, and not Trifolium ornithopodioides. Therefore, this newly discovered site at Ágota-puszta should be regarded as the first trustworthy occurrence of this species at the Hortobágy plain.
