Abstract

Pyrite and limonite petrifactions of a new type of axis are described from the Senni Beds, Lower Old Red Sandstone from Wales. The principal diagnostic character is a conspicuous, terete, centrarch xylem strand composed of tracheids with distinctive helical and annular secondary thickenings. Immediately outside the xylem is a zone of crushed cells. As nothing is known about the morphology and fertile parts of the plant a new form genus, Sennicaulis, has been erected. Its affinities are either with the Rhyniophytina or Trimerophytina. The Welsh specimens have been named Sennicaulis hippocrepiformis gen. et sp. nov.
