    Huttonia spicata (Sternberg) emend. and its spores, the Radnice Basin (Bolsovian), Carboniferous continental basins of the Czech Republic

  • Original language description

    Eleven specimens of Huttonia spicata from Vranovice, Chomle, Svinná and Břasy localities of the Radnice Basin were studied. The stratigraphical position of the cones is the Whetstone Horizon, Radnice Group of seams, Radnice Member, Lower Bolsovian. A newfamily Huttoniaceae is proposed. Huttonia was considered to have more than one sporangium on one sporangiophore. New research confirmed that each sporangiophore bears only one sporangium. In situ micro- and megaspores were isolated from type specimens of the species and are described for the first time from cones undoubtedly assigned to Huttonia spicata. Trilete laevigate microspores are of the Calamospora-type, but most microspores have very thin pseudosaccus-like layer envelopes within the trilete inner bodies. Laevigate trilete megaspores are of the Calamospora laevigata-type. Palaeoecology of Huttonia spicata is discussed.

  • Czech name

    Huttonia spicata (Sternberg) emend. and jeho spóry z radnické pánve (bolsov) karbonských kontinentálních pánví České republiky

  • Czech description

    Je popsáno jedenáct nálezů druhu Huttonia spicata z lokalit Vranovice, Chomle, Svinná a Břasy lv radnické pánvi. Stratigrafický rozsah šištic je radnické souslojí, radnické vrstvy, spodní bolsov. Je navržena nová čeleď Huttoniaceae. Huttonia byla interpretována jako fruktifikace s více sporangii na jednom sporangioforu. Nové morfologické výzkumy potvrdily, že každý sporangiofor nese pouze jedno sporangium. In situ mikro- a megaspory byly získány z holotypu a rostlin poprvé nepochybně náležejících druhuHuttonia spicata. Trilétní levigátní mikrospory rodu Calamospora jsou většinou obaleny velmi tenkou vrstvičkou pseudosaku. Levigátní trilétní megaspory odpovídají druhu Calamospora laevigata. Paleoekologické nároky druhu Huttonia spicata jsou diskutovány.
