The paper presents ten new localities of Orobanche pallidiflora Wimm. & Grab. from Poland (Middle Roztocze, Równina Be³ska plain, Wy¿yna Malopolska upland, Góry Kaczawskie Mts and Western Bieszczady Mts). Information on hosts, abundance and habitat preferences at the new localities is given and a supplemented map of the distribution in Poland is included.
New distribution data for 171 bryophyte taxa in the Roztocze National Park are provided. Among them there are 43 species protected by law in Poland, including 20 strictly protected species, as well as 13 species threatened in Poland. The research revealed 36 species (5 liverworts and 31 mosses) new for the region. Noteworthy is the occurrence of 19 mountain species and 10 bryophytes thought to be relicts of old-growth forests what confirms the specificity of nature of the Roztocze region. The most valuable and interesting finds are: mosses Campylophyllopsis sommerfeltii (Myrin) Ochyra, Dicranum viride (Sull. & Lesq.) Lindb., Buxbaumia viridis (Moug. ex Lam. & DC.) Brid. ex Moug. & Nestl. as well as liverworts Calypogeia suecica (Arnell et J. Perss.) Müll. Frib. and Cephalozia catenulata (Huebener) Lindb. A brief characterisations of these species are presented.
Chamaecytisus albus (Hacq.) Rothm. is an extremely rare species, which is inserted in many European red lists and red books. Its continuous range covers the south-eastern part of Europe. That species grows in intensely insolated and calcareous habitats of xerothermic grasslands. Only one station of White Broom had been known in the valley of the Bug river, near Hrubieszów, but in 2007 a new one was discovered near Jêdrzejów. That station is located the farthest in the north and the west in Europe and it is completely detached from the continuous range.
Glyceria striata (Lam.) Hitchc. is a North American species that has been recorded in most, semi-natural habitats in Europe, e.g. in meadows, bog springs, margins of water bodies. It is circumscribed within two taxa of lower rank: G. striata subsp. striata and G. striata subsp. stricta. Only G. striata subsp. stricta has been reported from Europe. This paper gives a list of the European locali- ties of the species (48) and describes two newly discovered localities in Poland (the Wyżyna Małopolska upland and the Western Carpathian Mts.). The distribution of G. striata in Europe is mapped and potential migration routes of the species are discussed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
