Abstract

Spergularia marina, a rare native halophyte and nationally vulnerable species, is reported from a new locality in southern Poland. It was found on 14 September 2016 in Mogilany, Lesser Poland Voivodeship, growing between paving stones at the Zakopianka road. Map of distribution of S. marina in Poland based on the ATPOL cartogram method is provided, and its possible pathways of introduction are discussed.

Abstract

This paper provides a list of 40 vascular plant species recorded in 2015–2017 in the Polish part of the Lithuanian Lakeland (north-eastern Poland), using the ATPOL cartogram method. Two native taxa Erigeron acris subsp. droebachiensis and Rorippa austriaca, one established alien Atriplex tatarica and one casual alien Aronia × prunifolia are reported as new to the flora of the region.

Abstract

The paper presents a regional red list of vascular plant species native to the Western Suwałki Lakeland, north-eastern Poland, based on the IUCN red list categories and criteria. The distribution and abundance data were obtained from the field floristic inventories carried out in 2008- 2016 using the ATPOL cartogram method. The historical occurrences of vascular plant species were revised in the field. The list comprises 203 species, including seven regionally extinct species, 43 critically endangered species, 49 endangered species, 25 vulnerable species, 48 near threatened species, and 31 data deficient species. The results are compared to the Polish national red list of pteridophytes and flowering plants and briefly discussed.

Abstract

The paper reports for the first time the occurrence of Erigeron acris subsp. angulosus in Poland. This rare European temperate plant was found in August 2014 in a former sand and gravel quarry, close to the Sobolewo reservoir in the town of Suwałki, north-eastern Poland. Species composition of the habitat is characterized by a phytosociological relevé based on the Braun-Blanquet method, diagnostic characters in comparison to the morphologically similar E. acris subsp. droebachiensis are presented using scanning electron microscopy imaging, and an identification key for E. acris s. l. in Poland is given.

Abstract

The present study provides a floristic list of twenty vascular plant species recorded in 2015-2016 in the Western Suwałki Lakeland, north-eastern Poland, by using the ATPOL cartogram method. Attention is drawn to the species Camelina sativa, Geranium columbinum, Rubus corylifolius aggr., Salix ×mollissima and Vicia pannonica, which are new to the regional flora. Through this study, the distribution status of Allium vineale and Erigeron acris subsp. serotinus in the region has changed from the category of very rare taxon to the category of rare taxon. Two newly recorded species, Camelina sativa and Vicia pannonica, may become established in the Western Suwałki Lakeland in the future as agricultural weeds.

Abstract

The paper presents a new Polish record of Senecio inaequidens, a perennial plant native to South Africa. It was found growing on roadside verge in Głogoczów, West-Beskidian Piedmont, southern Poland, on September 22, 2016. A map of distribution of S. inaequidens in Poland is presented using the ATPOL cartogram method and the pattern of its spread along motorways is discussed.

Pliszko A., 2014: A new Polish record of Dracocephalum thymiflorum [Nauja Dracocephalum thymiflorum radvietė Lenkijoje]. - Both. Lith., 20(1): 64-66.

The paper presents a new record of a rare casual alien Dracocephalum thymiflorum L. (Lamiaceae) in Poland. A small population consisting of 42 generative individuals of this species was found in May 2013 on railway embankment in Okuniowiec village near the northeastern boundary of the town of Suwałki in the Polish part of the Lithuanian Lakeland. The current distribution (according to the ATPOL cartogram grid) is given, and introduction pathways via railway transport and contaminated crop seed are recognized

Abstract

In September 2014, the casual occurrence of Agastache rugosa in Poland was confirmed. It was found on a ground heap between fallow and arable fields in Łbiska near Zalesie Górne in the community of Piaseczno, the Masovian Voivodeship (coordinates: 52°1′33.06″ N, 21°0′27.72″ E; the ATPOL cartogram unit: ED46). This rare species of Asian origin is cultivated in bee-plant gardens of some beekeepers in Poland. The map of distribution and mode of introduction with garden waste from horticultural farms were presented.

Abstract

This short note provides data on casual occurrence of Physostegia virginiana in Poland. It was found on abandoned allotments in the western part of the town of Skarżysko-Kamienna in 2015 (ATPOL cartogram unit: EE45). Its population consists of 153 generative ramets growing in three clumps. The habitat suggests that the plant probably escaped from cultivation with dumped garden waste.
