Opis:
We used chromosome data to verify the taxonomic affiliation of specimens previously recognized as Brachyactis ciliata. All analyzed plants were diploids based on x = 7 (2n = 2x = 14), the basic number characteristic for Symphyotrichum ciliatum, allowing the examined species to be shifted from the genus Brachyactis to the genus Symphyotrichum sect. Conyzopsis. The chromosome number (2n = 2x = 14) for specimens of S. ciliatum from Poland is reported for the first time.

Opis:
Species of the genus Orobanche (Orobanchaceae), parasitic on Centaurea in Central Europe, were previously considered to belong to the O. elatior group. At present, the taxon is differentiated into two species, O. elatior Sutton and O. kochii F.W. Schultz. The paper presents for the first time the distribution of O. elatior and O. kochii in Poland based on a critical revision of herbarium and the literature data, as well as the results of field studies conducted between 1999 and 2014. The majority of the species’ localities are in south Poland: Silesia-Cracow, Małopolska and the Lublin Uplands. The distribution of both species in Poland is mapped and chronologically organized, and is thus the most recent in Europe. The taxonomy, host preferences, and ecology are also discussed. Seeds of both species were also investigated using light and scanning electron microscopy, which resulted in the designation of diagnostic features. The new color form of O. kochii f. citrina is described and illustrated. An account of all revised herbarium specimens collected from Poland, deposited in Poland and neighboring countries, is presented.

Information on Potamogeton hybrids, their identification, taxonomy, ecology and distribution has not been sufficiently recognised yet. Based on characters of P. x salicifolius (= P. perfoliatus x P. lucens) from a new locality in Poland - the Gatno lake (the Kaszuby Lakeland in NW Poland) - general comments on Potamogeton hybrids identification are introduced. The description of P. x salicifolius morphology from the Gatno lake are presented. Analysis of quantitative morphological characters of these specimens provided new information on variability of this taxon. The distribution map of P. x salicifolius in Poland, the original draft of P. x salicifolius based on specimens from the Gatno lake and the table with comparison of P. x salicifolius and the characters of parental species are also provided.

Opis:
This paper presents the results of the research on the anatomical structure of the stems and leaves and on the sculpture of the nuts of the sedges from section Muehlenbergianae (L.H. Bailey) Kük. The results show, that the anatomical structure of the vegetative organs cannot be an effective criterion of a taxonomical division. The most important interspecific differences occur among shapes and size of the exocarp cells, and among the presence or absence of the silica bodies on the surfaces of the cells. The greatest variation in the features listed above is observed in Carex divulsa Stokes subsp. leersii (Kneucker) W. Koch.
Praca dotyczy próby zastosowania metod anatomicznych w taksonomii roślin i sprawdzenia przydatności poszczególnych cech budowy wewnętrznej w tworzeniu podziałów systematycznych, a także w uzupełnianiu nimi opisów morfologicznych. Dotychczasowe badania prowadzone w obrębie sekcji Muehlenbergianae (L.H. Bailey) Kük., oparte na znacznej liczbie cech morfologicznych, nie dały jednoznacznych rozstrzygnięć w kwestii relacji zachodzących pomiędzy taksonami tej grupy. Badania były prowadzone na materiale zielnikowym pochodzącym z Polski północnej i południowej. Szczegółowej analizie zostały poddane cztery cechy dotyczące liści, trzy dotyczące łodygi oraz jedna związana z budową owocu. Na podstawie przeprowadzonych badań okazało się, że w przypadku łodyg i liści cechy anatomiczne nie stanowią zdecydowanego kryterium taksonomicznego. Dopiero analiza skulptury orzeszka pozwoliła na wychwycenie różnic pomiędzy taksonami. Wyróżniono pięć typów egzokarpu, z których każdy reprezentował określony takson. Jednakże dokładne i jednoznaczne określenie kryteriów, na których miałby się opierać podział taksonomiczny, wymaga dalszych badań na materiale pochodzącym z całego obszaru zasięgu opracowywanych taksonów.

Opis:
The German Late Triassic archosaur Teratosaurus suevicus is a historically important taxon, being the first described rauisuchian. Unfortunately the holotype is a single element, a maxilla, which is poorly preserved and incomplete. We redescribe this maxilla and identify a single potential autapomorphy. The fragmentary type specimen complicates attempts to refer additional material to this taxon, and other unassociated archosaur and rauisuchian specimens from the Mittlerer Stubensandstein of Germany cannot be referred to T. suevicus with any degree of confidence. The stratigraphically older T. silesiacus, from the upper Carnian of Poland, is represented by a much more complete and better preserved specimen. Comparison of the maxillae of T. suevicus and T. silesiacus reveals that the two are distinct taxa, contra recent suggestions, but also that they do not share any synapomorphies or a unique combination of characters relative to Postosuchus kirkpatricki and other rauisuchians. Thus, the Polish material must be transferred to a new genus, Polonosuchus gen. nov. Both Polonosuchus and Teratosaurus are very similar to Postosuchus kirkpatricki, and the three taxa are likely closely related.

Opis:
An assemblage of well−preserved spinicaudatan crustaceans (“conchostracans”) is described from lacustrine late Carnian claystone at Krasiejów in southwestern Poland. Their shell microstructure is similar to that in extant spinicaudatans. Five species identified there are assigned to the genera Laxitextella, Menucoestheria (first record in the European Triassic), and Menucoestheria bocki sp. nov. and Krasiestheria parvula gen. et sp. nov. are erected. Specimens of Laxitextella laxitexta are the most abundant, comprising nearly half of the assemblage, those of Menucoestheria bocki one quarter, Laxitextella sp. A, Menucoestheria? sp., and Krasiestheria parvula form a minor component. Their ecological setting was probably similar to Recent relatives: temporary ponds of fresh water. The Late Triassic fauna in the German part of the same basin is closely similar to that in Poland. In Europe, the stratigraphic range of Laxitextella laxitexta is limited to the Middle Keuper (middle–late Carnian).

Opis:
This study present 9 species of colourless euglenoid flagellates found in a small peat bog in Budzyń, a village north-west of Cracow, which belongs to the Małopolska Upland (Southern Poland). This threatened peat bog is covered with rubble brought from neighbouring Cracow. Only ca 30% of its area is relatively little influenced by human activity. Many of the present species are rarely and infrequently reported from nature. Three species, including Rhabdomonas incurva Fresenius, Entosiphon obliąuum Klebs, E. ovatum Stokes, and one variety Menoidium pellucidum Perty var. gracile (Playfair) Popova have been recorded for the first time from Poland. Three species Astasia dangeardii Lemmermann var. dangeardii, Rhabdomonas costata (Korsikov) Pringsheim and Entosiphon sulcatum (Dujardin) Stein var. sulcatum Stein are new for the flora of Cracow-Częstochowa Upland. The remaining taxa: Menoidium pellucidum Perty var. pellucidum and M. tortuosum (Stokes) Senn var. tortuosum are very rarely recorded from Poland. For each species illustrations, taxonomic information and biogeographical data are given.

The distribution of four species of the genus Vulpia [V. myuros (L.) C.C. Gmel., V. bromoides (L.) S.F. Gray, V. ciliata Dumort. and V. geniculata (L.) Link] reported in Poland has been studied. Currently, V. myuros and especially V. bromoides are very rare species, and their greatest concentration can be found only in the Lower Silesia region. The number of their localities decreased after 1950 and it seems resonable to include both species in the "red list" of threatened plants in Poland: V. myuros in the EN category, V. bromoides in the CR category. V. ciliata and V. geniculata are very rare ephemerophytes and their localities not confirmed during ca 60 years are of historical interest only.

Morphological properties of sporocarps and spores of Endogone lactiflua (Zygomycota, Endogonales), a fungus for the first time found in Poland, are described and illustrated. Endogone lactiflua was wet sieved and decanted from a sample taken from the zone extending from the upper soil layer to rhizosphere of Pinus sylvestris growing in a forest dune in northern Poland. The recovered spores mainly occurred in large and compact sporocarps, although both small aggregates with a few spores and single zygosporangia of this fungus were also isolated. Endogone lactiflua is the fourth species of the genus Endogone found to occur in Poland. The distribution of the fungus in the world is also presented.

Taxonomic remarks, known distribution, ecological notes and new records in Central Europe for two species of Epigloea are provided. Many specimens recognized here under E. soleiformis characterize slightly wider and more ellipsoid ascospores than those described in the protologue but they are regarded as some kind of a phenetic variability of this species. E. soleiformis seems to be not only algicolous fungus but also facultatively lichenicolous on Placynthiella spp. and terricolous Peltigera spp. while E. urosperma is found to be exclusively lichenicolous on Placynthiella dasaea. E. soleiformis is new for the Western Carpathians and the Harz Mts, and E. urosperma is new for whole Carpathians.

The generic attribution of the Plio-Pleistocene Polish moles ?Neurotrichus polonicus and ?Neurotrichus skoczeni has been questioned several times in the past. The fossil material belonging to ?Neurotrichus polonicus and ?Neurotrichus skoczeni is re-evaluated here and a new diagnosis is provided on the basis of qualitative considerations. In addition, a Geometric Morphometric analysis of the humerus has been performed including both extant and extinct Neurotrichini and Urotrichini taxa for comparison. Our results proved the unique morphology of the Polish material suggesting a distinct taxonomic state. The morphological variations evidenced by the humeral shape analysis agree with the observed qualitative differences and support a new generic allocation. The new genus Rzebikia gen. nov. is proposed for all the material previoulsly ascribed to ?Neurotrichus polonicus and ?Neurotrichus skoczeni.
