Novelties in the vascular flora of Croatia

Abstract

We report on and discuss records of five species new to the vascular flora of Croatia. Calamagrostis canescens was found near Đurđevac in remnants of fen vegetation, and we consider it a critically endangered species in the flora of Croatia. Agrimonia procera is native or archaeophyte in central Croatia and its discovery is in accordance with its earlier use as a medicinal plant. Amaranthus emarginatus is an exotic newcomer that was previously found in urban habitats on the north Adriatic coast. Carex vulpinoidea and Oenothera suaveolens were shown to be locally established species, in meadows along the Kupa River, and on the bars of the Drava River, respectively. In addition, we present new distributional and ecological data on two neophytes (Cardamine occulta, Humulus scandens) that were only briefly mentioned in earlier sources from Croatia.

Assessing the Invasion Risk of Humulus scandens Using Ensemble Species Distribution Modeling and Habitat Connectivity Analysis

“…Even though it did not register a high contribution to the ensemble model ( Table 2 ), it is worth mentioning that the anthrosol, which is the dominant soil class occupied by H. scandens in Romania, along with the preferred soil texture, may confirm that the species prefers wet, alluvial habitats with loamy sand-clay soils, especially if they are disturbed. The habitats with H. scandens in Romania are similar to previous records from other European countries where it is invasive, highlighting its preferences for the alluvial, disturbed areas [ 13 , 24 , 26 ]. The alluvial habitats are preferred not only by H. scandens but also by other invasive or potentially invasive lianas in Europe.…”

“…The study area is in the southern and central parts of the Danube basin, where the species has expanded in recent years [ 24 , 26 ]. We selected a geopolitical boundary (Romania) due to the standardization of the occurrence collection sampling effort in the field within the above-mentioned research project, but also because part of the categorical geospatial datasets was locally available within a specific format.…”

“…The species is also found as a decorative plant in some major retail markets across Europe, which furthers its dispersion potential. In Europe, H. scandens has become invasive in southern France [ 16 ], Hungary [ 13 ], Italy [ 23 ], and Northern Croatia [ 24 ]. It is subspontaneous in the Pannonian plain, Serbia [ 25 ], and Bulgaria [ 26 ], and has been rarely recorded in Austria [ 27 ], Belgium [ 28 ], Czech Republic [ 29 ], Germany [ 13 ], Denmark [ 30 ], Poland [ 30 ], Slovenia [ 13 ], Slovakia [ 31 ], Sweden [ 32 ], Switzerland [ 13 ], Ukraine [ 33 ], and until now, in Romania [ 34 , 35 ].…”

Taxonomy and distribution of Taraxacum sect. Erythrosperma (Asteraceae) in Poland

“…General distribution. Widely distributed European species reported in France, Ireland, Great Britain, Italy, Switzerland, Belgium, the Netherlands, Germany, Denmark, Austria, Croatia, Poland, Norway, Finland, Sweden, Romania, Croatia, Moldova, Ukraine and Estonia (Marklund 1938;Van Soest 1967;Doll 1973b;Tutin et al 1976;Tacik 1980;Fedorov 1989;Mosyakin and Fedoronchuk 1999;Nikolić 2000;Uhlemann 2003;Wendt and Øllgaard 2015).…”

Ethnobotanical Survey of Culturally Important Plants and Mushrooms in North-Western Part of Croatia

“…There are no pronounced industrial activities and traffic is relatively low in comparison with the urbanized part of Croatia [ 31 ]. Thus, in this area, rare and endangered species occur [ 32 ]. Osijek-Baranja County represents one of the most intensive areas of plant production among the counties in Croatia [ 33 ].…”
