Noeggerathiales have been previously linked to horsetails and ferns, but are currently believed to be progymnosperms, being woody like seed plants, but still producing spores rather than seeds.

[1] Noeggerathiales had a tree fern like appearance, with leaves sprouting from the top of an unbranched trunk.

They were primarily confined to the wet tropical regions where there was no frost.

[2] One form, Paratingia wuhaia, resembled a small fern reaching from two to several meters in height.
