  • The occurrence of Pterygoneurum squamosum Segarra et Kürschner on a reclaimed waste storage near town Győr (NW Hungary)
    23-27

    In the article a new locality, range map and habitat description of Pterygoneurum squamosum is provided from Hungary. Differently from up to the present known localities, the moss was found on anthropogenic habitat, eroded and clayey soil surface. Considering the climatic and soil conditions there, probably this rare Mediterranean species has wider ecological tolerance, so we come across it on further man-made habitats, as well as on loess walls.

  • The flora of the Sárvíz plain (Mezőföld, Hungary)

    In this paper, I present chorological data on the plants growing on the alluvial plain of the Sárvíz river in eastern Transdanubia, Hungary. Species characteristic of reed and sedge marshes, salt lakes and alkali flats, as well as remnants of hardwood forests and mesoxeric grasslands are listed in the enumeration. Since 2004, I have confirmed the occurrence of 50 species previously not recorded in the study area. Here, I report the species names, followed by data on the locality: the name of the township, the geographical name of the locality, and the code(s) of both grid systems, the Central European Flora Mapping System (CEU) and the UTM. Sites where I observed or collected the species after 2004 are in bold. Names of species new to the study area are underlined.

  • Taxonomic revision of alien Ludwigia species in Hungary

    Some tropical Ludwigia species have been planted as ornamentals in Hungarian thermal springs since the 1920s. Although they have become naturalised or even invasive in a few places, their specific identity remained generally uncertain. Our herbarium and field studies revealed that three species of alien water-primroses occur in Hungary. The most frequently planted one is Ludwigia repens, which is, however, a sporadic species in its native distribution area. We have found this species in several parts of the country. Although a few escaped and self-sustaining populations were also observed, this species has appeared to be non-invasive so far. Ludwigia grandiflora appeared in Hungary at the beginning of the 2000s. At the moment it is known from three localities, though spreading rapidly, becoming already invasive in its locality at Tata city. A similar species, L. peploides has recently been reported from two localities, where it forms small stands; the success of its naturalisation can be assessed in the future. We found no evidence for the Hungarian occurrence of L. alterniflora that had been published from Eger city. Therefore we suggest deleting this species from the current Hungarian checklist.

  • Distribution of Pseudoleskea saviana (De Not.) Latzel in Hungary

    Three new localities of the moss species Pseudoleskea saviana (De Not.) Latzel were discovered in the Börzsöny Mts in the administrative district of Perőcsény village, North Hungarian Mountains (Nagy-Hideg-hegy, near Hangyás-bérc, in the col between Csóványos and Magosfa). Small populations were found on shaded andesitic boulders in mixed deciduous forests. Up to the present, only old collections of the species were known from a single locality in the Mátra Mts; therefore, the red list status was data deficient. The morphological distinction of P. saviana from P. incurvata, its closely related congener also reported from Hungary is not always exempt from difficulties. However, the presence (P. saviana) or absence (P. incurvata) of a central strand in the stems, the shape of mid-leaf cells (P. saviana: more elongated, 3–4 times as long as wide; P. incurvata: at most twice as long as wide), as well as the shape of the outer basal cells (P. saviana: quadrate or shortly rectangular; P. incurvata: transversely elongated) seem to be reliable distinctive features.

  • New occurrence of Myricaria germanica in a Hungarian gravel pit

    This paper reports the second Hungarian synanthropic occurrence of the rare Myricaria germanica. One flowering individual was found in a gravel pit near Hejőpapi (NE Hungary). The closest known population of the species is 60 km far from newly found locality. This occurrence indicates effectivness of anemochory. It seems, that abandoned gravel pits may be potential habitats of this threataned shub species.

  • Annual Lythrum species in Hungary: revision of the subgenus Hyssopifolia

    Four ephemeral Lythrum species have been recorded from Hungary so far. Lythrum hyssopifolia is widely distributed in the whole country. Most occurrences of L. tribracteatum are located in southeastern Hungary and alongside the Danube. The Central Asian L. linifolium was reported from a single locality (Tiszaug village, E Hungary) in 1954, which is the only European record of this species. However, we have ascertained that the voucher specimen of this record differs from L. linifolium in some morphological traits, but strongly resembles L. borysthenicum that is distributed in the Mediterranean and steppe regions of eastern Europe. Based on our revision we suggest deleting L. linifolium from both Hungarian and European checklists. The former Hungarian occurrence of L. thesioides is confirmed by vouchers.

  • Hybrid leopard’s bane (Doronicum ×sopianae) in the West-Mecsek Mts (SW Hungary)

    The hybrid of leopard’s bane (Doronicum orientale Hoffm.) and the Hungarian leopard’s bane (Doronicum hugaricum (Sadler) Rchb.f.) was discovered by Tamás Nendtvich in the Mecsek Mts over Pécs in the 1820’s. During the past two centuries several researchers confirmed the occurrence of this plant in the region. The occurrences of the hybrid ever known are concentrated in a relatively limited range, and the single currently known occurrence is on “Zsuppon-parlag”.  In this paper, I report a new occurrence, found on 16th April 2020, close to the village of Kővágószőlős, which is 8 km away from the single currently known locality. I found only one flowering specimen, as well as five vegetative individ­uals with leaf rosettes. The parental species grew only 50 cm away from each other. Here, I provide a detailed morphological description about the flowering individual, and a vegetation relevé of the ac­companying species in a 10×10 m quadrat around the hybrid plant.

  • New occurrence of Caldesia parnassifolia (L.) Parl. in Hungary

    Caldesia parnassifolia is a critically endangered and strictly protected species in Hungary. It was known only from one locality of occurrence so far, where it was last reported in 2003. Its new occurrence was discovered in Somogy county, in 2010. It appeared in an artificial pond created in the place of an originally swampy depression. Based on this newly discovered occurrence we can assume that other potential populations might still exist in South-Transdanubium, which could be rediscovered if similar conservation measures occur.

  • Rediscovery of Gymnadenia frivaldii Hampe ex Griseb. at its northern distribution limit (Eastern Carpathians, Romania)

    Frivald’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.

    A new locality of the moss species Anacamptodon splachnoides (Froel. ex Brid.) Brid. was discovered in a Turkey oak-dominated forest stand in the Bükk Mts. (near Varbó village, North Hungarian Montains). A small population of this threatened bryophyte was found in a wet root-hole of a living Quercus cerris L. tree.
