  • Finds of selected ascomycetes in western Moravia (Czech Republic) in 2013

    Jaroslav Čáp

    Five ascomycetous species from the authorís collection with insufficient or absent data about their occurrence in the Czech Republic are discussed. A sixth taxon is mentioned, found on a new host, previously unpublished. Short descriptions of haracteristic features of the collected material are added. A preliminary key to...

    Five ascomycetous species from the authorís collection with insufficient or absent data about their occurrence in the Czech Republic are discussed. A sixth taxon is mentioned, found on a new host, previously unpublished. Short descriptions of haracteristic features of the collected material are added. A preliminary key to identification of the white-coloured members of the genusLachnum growing on grasses (Poaceae) is provided.

  • Typoid potential of cultivated introduced woody plants: A case study of the Wilson collections in Průhonice Park, Czech Republic

    Jan Kirschner & Ivo Tábor

    Nomenclatural aspects of extant cultivated progenies of elements of original material, and specimens derived from them, are discussed. The current nomenclatural code gives a single comparable example, not applicable to the situation described. The term ìpseudotypeî, previously coined for the specimens prepared from cultivated...

    Nomenclatural aspects of extant cultivated progenies of elements of original material, and specimens derived from them, are discussed. The current nomenclatural code gives a single comparable example, not applicable to the situation described. The term ìpseudotypeî, previously coined for the specimens prepared from cultivated progeny of type specimens, may be useful, provided that its definition is extended. The typoid potential of specimens from the cultivated progenies of introduced woody plants is exemplified by the material (seed, specimens) collected by E.H. Wilson in China and cultivated in Pr˘honice Park, Czech Republic.

  • Autumn hawkweed (Hieracium sabaudum) in the Czech Republic

    Petra Bidmanová, Olga Rotreklová, Jiří Danihelka, Jindřich Chrtek Jr.

    The distribution of Autumn hawkweed Hieracium sabaudum in the Czech Republic is examined, based on specimens held by 28 public herbaria. This species, classified within Hieracium sect. Foliosa, is one of 58 native hawkweeds within the Czech flora. In total 2793 herbarium specimens of H. sabaudum collected in the country were...

    The distribution of Autumn hawkweed Hieracium sabaudum in the Czech Republic is examined, based on specimens held by 28 public herbaria. This species, classified within Hieracium sect. Foliosa, is one of 58 native hawkweeds within the Czech flora. In total 2793 herbarium specimens of H. sabaudum collected in the country were revised, of which 1668 (i.e. approx. 71%) were originally identified correctly (including taxonomic synonyms). Based on the number of specimens revised and data from botanical databases, the distribution map presented here may be considered representative. Hieracium sabaudum occurs in most parts of the country, although it is rare in mountain areas, or absent from them. In the Czech National Phytosociological Database, its occurrence is recorded over a broad scale of various plant communities, most frequently in oak-hornbeam, thermophilous oak and pine forests and their fringes, in scrub, heath and in various types of secondary habitats such as quarries and roadsides. Using flow cytometry measurements and chromosome counts, ten plants originating from five populations were shown to be triploid (2n ~ 3x) and one plant was 2n = 27.
