Description

The pollen organ Pteruchus differs from other seed fern pollen organs in having numerous pendant pollen sacs from a blade-like head, in an arrangement similar to an epaulette.

Whole plant reconstructions

  • Pteruchus africanus may have been produced by the same plant as Umkomasia macleanii (ovulate organs) and Dicroidium odontopteroides (leaves), based on cuticular similarities between these leaves and reproductive structures at the Umkomaas locality of South Africa.
  • Pteruchus barrealensis may have been produced by the same plant as Umkomasia feistmantelii (ovulate organs) and Dicroidium zuberi (leaves), based on cuticular similarities between these leaves and reproductive structures near Sydney Australia.
