Pinguicula vulgaris (Lentibulariaceae) in north eastern Poland. Fragmenta Floristica et Geobotanica Polonica 8: 105–111. Kraków. PL ISSN 1640 629X. ABSTRACT: Pinguicula vulgaris L. has previously been recorded from four localities in the Suwałki Lakeland in the north easternmost part of Poland, but in at least at two of these stations the species has not been observed within the last decade. A new locality for this species was discovered in June 2000 in a small fen on the left hand side of the Kunisjanka stream in the village of Berżniki south east of Sejny. This is the richest locality for P. vulgaris in this part of the country and approximately 210 individuals were observed in an area of about 100 sq. m. The locality is described in detail and accompanying vascular plants and bryophytes are enumerated. Amongst the latter, four species are of special interest, namely Paludella squarrosa, Tomentypnum nitens, Helodium blandowii and Bryum weigelii which are considered to be glacial relicts in Central Europe. The local distribution of the species in north eastern Poland is presented and a distribution map showing its range in Poland as a whole is also provided.

Algae commensal community in Genlisea traps

nr 1

The community of algae occurring in Genlisea traps and on the external traps surface in laboratory conditions were studied. A total of 29 taxa were found inside the traps, with abundant diatoms, green algae (Chlamydophyceae) and four morphotypes of chrysophytes stomatocysts. One morphotype is described as new for science. There are two ways of algae getting into Genlisea traps. The majority of those recorded inside the traps, are mobile; swimming freely by flagella or moving exuding mucilage like diatoms being ablate to colonize the traps themselves. Another possibility is transport of algae by invertebrates such as mites and crustaceans. In any case algae in the Genlisea traps come from the surrounding environment. Two dominant groups of algae (Chladymonas div. and diatoms) in the trap environment, show ability to hydrolyze phosphomonoseters. We suggest that algae in carnivorous plant traps can compete with plant (host) for organic phosphate (phosphomonoseters). From the spectrum and ecological requirements of algal species found in the traps, environment inside the traps seems to be acidic. However, further studies are needed to test the relations between algae and carnivorous plants both in laboratory conditions and in the natural environment. All the reported taxa are described briefly and documented with 74 LM and SEM micrographs.
