Pelourdea
Pelourdea is an extinct genus of conifer. Species belonging to the genus lived from the Triassic to the Middle Jurassic and have been found in Europe and North America. Members of the genus have long pointed leaves (up to  long and  wide) whose base clasps a central shoot. The attachments are spiral. The shoots were  in height and the plant was likely herbaceous. The lack of reproductive structures in known fossils have hindered determination of the taxonomy. References
