Abstract

Mount Flora at Hope Bay, in northernmost part of Antarctic Peninsula, is a famous Jurassic flora locality. It has already been studied for a hundred years, but however, it is still possible to find there new taxa. Based on two species of liverworts found at Mount Flora (Schizolepidella gracilis and Schizolepidella birkenmajeri sp. nov.), the present study discusses affiliation of the genus Schizolepidella to liverworts. The new species Schizolepidella birkenmajeri is erected.

Abstract

The well−known Jurassic macrofloras from Hope Bay at the northernmost tip of the Antarctic Peninsula continue to yield new taxa . This paper reports on a new type of plant re− productive organ. The affinity of this organ r emains unclear; it may be affiliated with the Schizaceae or Osmundaceae, but similarities to po llen organs of the Podocarpaceae are also discussed. Because the fossils differ from hitherto known Mesozoic fertile fronds and conifer pollen organs in some details, the new taxon, Spesia antarctica nov. gen. et sp. is proposed.
