The sub-arborescent lycopsid Omphalophloios feistmantelii (O. Feistmantel) comb.nov.emend. from the Middle Pennsylvanian of the Czech Republic
Original language description
About 88 compression specimens of sub-arborescent lycopsid Sporangiostrobus feistmantelii (Feistmantel) Němejc from the middle Westphalian strata of central and western Bohemia, Czech Republic, were studied. A new combination Omphalophloios feistmantelii(O. Feistmantel) comb.nov.emend. is proposed and original diagnosis is emended. Basal vegetative part of the stem bears rhomboidal leaf cushions with a bell-shaped leaf scar. A larger part of the stem, however, consists of a fertile axis bearing oval sporangia about 5-6 mm wide and 7-8 mm long. O. feistmantelii is estimated to be about 2 to 3 m tall plant of columnar habit sometimes ones or twice dichotomizing in fertile part of the stem. Fertile zone matured from bottom to top shedding first more than20 cm long grass-like laminae and than rippened sporangia, leaving only pedicels on the naked axis (Puertollania disarticulation stage). This suggests a continuous reproduction since the plant reached maturity stage up to the end of its
