Progymnosperm

Progymnosperms are ancient plants that don't exist anymore. They were like woody plants with spores and probably came from trimerophytes.^[1] Later, they led to the development of gymnosperms, which are the ancestors of acrogymnosperms and angiosperms (flowering plants). People sometimes call them Progymnospermophyta or Progymnospermopsida.
