Checklist of the vascular flora of Wielkopolska (Poland): casual alien species

Abstract

The list of alien vascular plant species only temporarily occurring in Wielkopolska refers to the previously published list of native and permanently established plants. Together, these two lists document the vascular flora of this region at the beginning of the 21st century. The current list, like the previous one, is a result of critical analysis of both contemporary and historical data, collected since the beginning of the 19th century. All information accessible in herbarium collections, publications and unpublished materials was used. A critical analysis was conducted at the taxonomic, nomenclatural, chorological and habitat levels, based on the verification of negative information not supported by sufficient arguments. The list is presented in an alphabetical order. Information on each species includes: family affinity, life form, geographic and historic status. In cases particularly disputable, the standard characteristic of a species was supplemented with an additional commentary.

Chemical variability of common skullcap (Scutellaria galericulataL.) wild growing in the area of eastern Poland

“…and common skullcap (Scutellaria galericulata L.). Among these taxa, common skullcap is the only species widespread all over the country, others are rare or very rare [19][20][21][26][27][28][29]. Literature data indicate that only common skullcap has been used in the folk medicine [1,24].…”

Endangered flora of Gdańsk Pomerania – its distinctiveness and diversity

“…It is highly valuable, which is due to the fact that it concerns regional flora, and, as it is well known, the scale of species threat changes with respect to the size and habitat diversity of a given area. Numerous regional red lists have been created for different parts of our country, for example: a red list for Lower Silesia (Kącki et al 2003), Greater Poland (Jackowiak et al 2007), Lublin region (Cwener et al 2016, Małopolska Upland (Bróż & Przemyski 2009), Western Pomerania (Żukowski & Jackowiak 1995) or Kuyavian-Pomeranian region (Rutkowski 1997).…”

Spergulo-Chrysanthemetum segeti (Br.-Bl. et de Leeuw 1936) R. Tx. 1937 in the Drawsko Lakeland (Western Pomerania)

“…segetum is recognized as threatened with extinction [30,31]. Nationwide, it is critically threatened with extinction [32], in Opole Silesia -vulnerable [33,34], in Greater Poland -little endangered [35,36], and in Lower Silesia -endangered with extinction [37]. For the first time, it was presented and described in the Kashubian Lakeland by Passarge [38], and later by Herbich [39].…”
