Data on the occurrence of alien plants in Western Transdanubia (Hungary)
185–188Views:760In his publication the author provides data on the occurrence of 11 alien species in Western Transdanubia. Three of these species (Euphorbia maculata, Euphorbia peplus, Muscari armeniacum) were observed to have spread rapidly in the past decade. It can be concluded that 4 species (Artemisia annua, Crocus banaticus, Polycarpon tetraphyllum, Veronica filiformis) have reached a state which is close to naturalization, while the other reported species (Euphorbia lathyris, Senecio inaequidens, Silybum marianum, Veronica peregrina) are casual in this region at present.

Some floristic data from surroundings of Kötcse (South Transdanubia, West Outer Somogy)
74-80Views:99There are very few published and documented floristic data from the hills of the SW region of Hungary called 'Outer Somogy'. This paper present the occurrence data of 31 vascular plant species from the western part of this region. Among them 14 taxa are legally protected and further 17 taxa are sporadically occurring. The records were collected within the administrative area of villages Karád, Kereki, Kötcse, Nagycsepely, Szólád (Nezde) and Teleki. Most data were recorded in 2014. This is the first report on the occurrence of 1) Neotinea ustulata subsp. aestivalis in South Transdanubia, and 2) Epipactis microphylla and E. tallosii in Outer Somogy. Data provided on the occurrence of Cirsium boujartii on the northwestern border of the distribution area of this insufficiently known species.

Campylopus flexuosus (Hedw.) Brid. in the Western Mecsek Mts. (South Transdanubia, Hungary)
28-37Views:133During a field survey in 2014, new localities of Campylopus flexuosus, were found in humid acidophilous oak and beech forests in the Western part of the Mecsek Mts. As a new element of the Hungarian bryoflora, C. flexuosus was discovered in 2013 in the Bakony Mts by Peter Erzberger and Csaba Németh. The localities of the sometimes extensive stands are enumerated, the size of the populations is estimated and the associated bryophyte and higher plant species are listed. Some morphological differences between C. flexuosus and the similar moss Dicranum flagellare are described and illustrated. Some interesting results of a revision of D. flagellare specimens in BP are compared with the actual distribution of C. flexuosus and lead to the conclusion that this species can be treated as a potentially expansive moss in humid acidophilous forests of the Mecsek Mts.

Interesting moss and liverwort records from the Western Mecsek Mts (South Transdanubia, Hungary)
29-38Views:84During an extensive field work in the acidophilous forests and fens of the Western Mecsek Mts. current localities of several species, which haven’t been recognised here for 50 years, were revealed (e.g. Bazzania trilobata, Diphyscium foliosum, Scapania nemorea). The authors also found some new stands of regionally and/or locally rare taxa (e.g. Buxbaumia aphylla, Dicranum tauricum, Jamesoniella autumnalis, Lepidozia reptans, Sphagnum squarrosum) as well as species new to the moss flora of the Mecsek Mts. (e.g. Aulacomnium androgynum, A. palustre, Calliergon cordifolium, Hedwigia stellata). Both investigated habitat types were found to be infected by invasive moss (Campylopus introflexus) and liverwort (Riccia rhenana) species. It is noteworthy that most of the species were found in winter or at the beginning of spring, when most vascular plants are inactive and their coverage is negligible. In this period moss and liverwort taxa are active, and are therefore easily noticeable. The authors raise the possibility that the expansion of Dicranum tauricum in Hungary is a consequence of former coniferous (especially Pinus spp.) plantations, since the old, dead trunks of pine species can serve as stepping stones to colonization for this taxon.

Occurrence and habitat conditions of Gagea minima along the Sorok stream (W Hungary)
189–194Views:136Gagea minima (L.) Ker Gawl. is a Eurasian bulbous species. It occurs sporadically in Hungary, but so far only one current occurrence is known from the Western Transdanubia. In recent years, a large metapopulation has been found in a 15 km long section of the Sorok stream. Its habitat is the high sandy bank above the stream, where it lives mostly in nitrophilous vegetation under non-native tree species. Its long-term persistence in this secondary habitat may have been facilitated by its bulbs, which may have been regularly dispersed by periodic disturbance. Myrmecochory may also have played a role in the local establishment of subpopulations. A number of recently found populations indicate that data on the distribution of the species is still incomplete. The lack of data is probably due to its short flowering period and relative inconspicuousness. Gagea minima is considered a valuable relict species in the altered environment of the Sorok stream and its surroundings.
