Název v původním jazyce

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

Popis výsledku v původním jazyce

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.
