Rediscovery of Gymnadenia frivaldii Hampe ex Griseb. at its northern distribution limit (Eastern Carpathians, Romania)
213-220Views:187Frivald’s Gymnadenia is a very rare Balkan species in the South-Eastern Carpathians. The specific epithet “frivaldii” honours Imre Frivaldszky (1799–1870), a Hungarian naturalist. The species occurs in the drawdown zone of mountain fens of the Balkan Peninsula (Bulgaria, Romania, Greece, Macedonia, Montenegro, Albania), at elevations between 1000 and 2300 m. In the Carpathians the species was first reported from the Ţarcu Mts (Southern Carpathians) by János Heuffel. In 1874 Simonkai collected a specimen (BP 33967) in the Retezat Mts, but he was uncertain about its identity, thus this record eventually appeared as G. albida (Pseudorchis albida) in his monograph. Since then the species has been found at several localities in both the Retezat Mts (Mt Peleaga, Zănoaga, Zănoguţa, Ana and Bucura glacial lakes, Judele Valley) and the Ţarcu Mts. This paper reports on the discovery of Frivald’s Gymnadenia in the area of “Szökő-láp” (Harghita Mts, Eastern Carpathians), which can be considered a confirmation of the old literature record. This is the northernmost locality of this Balkan species known so far. The chorology and conservation status of G. frivaldii in the South-Eastern Carpathians are discussed.

×Pseudorhiza bruniana in the Harghita Mts (Romania, E Carpathians)
249–250Views:168The discovery of a single individual of ×Pseudorhiza bruniana (Brügger) P.F.Hunt (Dactylorhiza maculata (L.) Soó × Pseudorchis albida (L.) Á. Löve & D. Löve) in a fen meadow of the Harghita Mts (Romania, East Carpathians) is briefly discussed. This is the first record of the nothotaxon in Romania, as well as in Central Europe.

Lectotypification of Thesium kernerianum Simonk.
69-74Views:84Thesium kernerianum is an endemic species of the Eastern Carpathians (in broad sense). The paper includes a survey of the discovery as well as the literature and herbarium records of this species. The name is lectotypified, and a few inaccuracies appearing in the literature are corrected.

The Sea milkwort (Glaux maritima) in the Carpathian Basin
10-20Views:318Sea milkwort (Glaux maritima L.) is a broadly distributed species in the northern hemisphere, inhabiting primarily maritime habitats from the arctic to the temperate zones. It is also found inland in semi-arid and arid regions with saline soils. Its status in the Carpathian Basin has become very uncertain owing to the lack of known extant populations. To evaluate its current status, I review all known occurrences within the Carpathian Basin where this species has been recorded or collected, and report five new localities of the species in Hungary, all in the western part of the Great Hungarian Plain. I also analyze habitat relationships of the species using traditional phytosociological relevés. Review of species distribution data in the Carpathian Basin revealed that sea milkwort has undergone severe reduction in population number and disappeared from many localities. Currently, only a few populations can be found in this region: the Northern Carpathians in Slovakia and the western part of the Great Plain in Hungary. In Transylvania (Romania), only a single population has been reported recently suggesting the critical status of the species there. Features of the habitats confirm the halophytic nature of the species and its fidelity to wet saline meadows. Its common accompanying species are mostly broadly distributed, salt-tolerant plants. Heterogeneity of the samples in species composition suggests that sea milkwort is not a habitat-specialist species. Several of its common associates in Hungary are also found in sea milkwort habitats in Mongolia, Asia and Utah, North America. Based on the available evidence, sea milkwort shall be considered a severely threatened plant in the Carpathian Basin. Characteristics of the vegetation in its habitats do not explain its occurrence in mountainous environments.
